The Survival of Aboriginal Australians through the Harshest
Time in Human History: Community-Strength
James A. Charles, Deakin University

Aboriginal People have inhabited the Australian continent before time began, but
archaeologists and anthropologists state there is evidence for approximately 51,000 to 71,000
years of continual habitation. During this time, the Australian continent has experienced
many environmental and climatic changes, which have contributed to mass animal extinction.
The skeletal remains of Aboriginal Australians were examined for evidence, which may be
indicative of fast running which would assist survival. The skull and mandible bones of the
Kaurna People were examined for signs evolutional traits related to survival. Aboriginal
culture, knowledge of medical treatment and traditional medicines were also investigated.
Oral storytelling of factual events, passed down unchanged for millennia, contributed to
survival. The Kaurna People exhibited evolutionary facial features that would have assisted
survival. Kaurna People had excellent knowledge of medicine and the capacity to heal their
community members. The process of mobility and relocation may have embedded the need to
be mobile in some Aboriginal Australian cultures, and why many Aboriginal tribes did not
invest too much time and resources in building permanent structures and dwellings.
Navigating these extremely harsh, rapidly changing conditions is an incredible story of
survival of Aboriginal Australians. The findings of this investigation suggest that Aboriginal
Australians’ survival methods were complex and multi-faceted. Although this paper could not
examine every survival method, perhaps Aboriginal Peoples’ knowledge of flora and fauna,
(for nourishment and medicine) living in clans, and avoiding mass cohabitation was
paramount to our survival.

Introduction
Aboriginal People have a sacred
connection to our land and we have inhabited
the Australian continent before time began,
and this has been expressed by Aboriginal
Australians in our Dreaming stories,
songlines, dance, and artworks (Brazil, 2000;
Charles, 2015; Mountford, 1981; Taçon,
1991). Archaeologists and anthropologists
estimated that Aboriginal People have
inhabited the Australian continent for
approximately 51,000 to 71,000 years
(Malaspinas et al., 2016) during the
Pleistocene period (Barker, Jones, McKay, &
McLeod, 2001). During this time, there has
been many extended periods of stability and
plentiful food supply. However, the
Australian continent has experienced many
environmental and climatic changes (i.e.,
fluctuating temperatures, ice ages, fluctuating
CO2 levels, extremely high dust levels, high
ice volume, high winds, large scale bush
fires, glacial movement, low rain fall,
extreme arid conditions, limited plant
growth, evaporation of fresh water lakes, and
dramatic sea level fluctuations. Please see
Figure 1) All of these events have contributed
to mass animal extinction (Bowler, 1976;
Fielding, 2008; Johnson, 2006; Malaspinas et
al., 2016; Monroe, 2011).
Figure 1
Note. Red graph (temperature), Purple graph
(dust level), Grey graph (ice volume), Yellow
graph (CO2 level) x-axis is time in years and
y-axis is volume (Best, 2016).
The very shape of the continent has
changed dramatically with the drop and rise
of sea levels, where approximately 8,000-
10,000 years ago the continent was much
larger with sea levels 100-150m lower than
the current sea levels in 2018 (please see
Figure 2) (Monroe, 2011; Voris, 2000). At
this time of low sea levels, the Australian
state of Tasmania to the south and the nation
of Papua New Guinea to the north created
land bridges to mainland Australia. The Great
Barrier Reef on Australia’s east coast was
above sea level, the land mass at that time
was much greater than today, and created an
ancient super continent i.e., Sahul
(Malaspinas et al., 2016).

changes and archaeological sites for selected
periods between 35,000 and 8,000 year ago
(Ulm, 2016).
Surviving in Australia over the
millennia, over some extended periods,
would have been relatively easy with food
sources and fresh water plentiful. However,
over some extended periods it would have
been incredibly difficult, where some of the
environmental and climatic changes would
International Journal of Indigenous Health, Vol. 15, 2020

have been catastrophic for many Aboriginal
tribes and unimaginably difficult by today’s
relative mild environmental conditions. The
incredible speed of climate change would
have required great adaptability of our
ancestors (Voris, 2000), and many would
have found it extremely difficult to cope
with these drastic and sudden changes
(Monroe, 2011).
This paper focuses on the incredible
survival story of Aboriginal Australians
through a period from approximately 32,000
to 17,000 years ago which would have been
difficult for all forms of life on the continent
to survive (please see Figure 1). This paper
will also examine Aboriginal Australian
knowledge, Dreaming stories, and cultural
practices to investigate links with modern
scientific facts. During this time period
(32,000 to 17,000 years ago) the temperature
would have been approximately 10-20
degrees Celsius lower than today, likely
linked to extremely low CO2 levels at that
time. The depletion of plant life from low
temperature, high winds, bush fires, and low
rainfall and consumption of plants from
large herbivores would have contributed to
the extremely high dust levels and low
visibility also seen at this time. This
reduction of plant life may have contributed
to mass extinction of large herbivores
inhabiting Sahul at this time and the domino
effect that would have also contributed to
extinction of large carnivores and impacted
on Aboriginal Peoples’ food source
(Johnson, 2006). One of the most
challenging times to survive on Sahul was
approximately 25,000 years ago at the last
ice age (Williams, Ulm, Cook, Langley, &
Collard, 2013). When the continent became
incredibly arid, CO2 levels were at a low
point, plant life would have struggled to
grow, temperature was at its lowest point for
millennia, dust levels reached its peak,
visibility was low and fresh water lakes
emptied (Figure 1-3) (Williams et al., 2013).
Conditions were extremely harsh and it is
thought that the population of Aboriginal
Australians declined by approximately 60%
(Williams et al., 2013). Although there were
many extended difficult periods to survive
on Sahul, it is this period approximately
25,000 years ago which would have required
the knowledge passed down from our
ancestors about environmental change, and
adaptability, and it is a truly incredible feat
of resilience by the Aboriginal People of
Australia. These conditions were far harsher
conditions than those experienced when
Neanderthals became extinct 70,000 to
50,000 years ago (Shea, 2008), although
there is some evidence Neanderthals
survived up until approximately 28,000
years ago (Finlayson et al., 2006). This
paper will investigate the incredible survival
story of Aboriginal People, through some of
the harshest conditions in human history, the
link between scientific evidence, and the
strength of Aboriginal cultural knowledge
and oral history.
Methods
Scientific and Aboriginal evidence
was collected for comparison. Footprints
from Lake Mungo (Mungo National Park,
NSW Australia) were examined to predict
foot arch height and approximate the speed
in which some Aboriginal men were
running. The skeletal remains from
Karraundo-ngga (Kaurna language for
Hindmarsh area in Adelaide SA Australia)
including the broken femur bone of a
Kaurna (Aboriginal) man was examined for
treatment and therapy. The skull and
mandible bones were examined for signs of
evolutional traits related to survival in tough
environmental conditions. Aboriginal
culture, and knowledge of medical
treatment, therapies, and traditional
medicines were investigated that may have
contributed to survival.

Relationship
The authors are Kaurna (Aboriginal)
men from the Adelaide Plains in South
Australia and have community, cultural, and
ancestral connections to the Kaurna People
examined in this paper. The Kaurna People
are the traditional owners of the Adelaide
Plains and we still maintain our cultural
heritage, beliefs, and connection to our land
and waterways. The authors also have
relationships with many Aboriginal and
Torres Strait Islander communities around
Australia. Written approval from the
Willandra Lakes Region World Heritage
Area Technical and Scientific Advisory
Committee and the Community
Management Council (TSAC and CMC),
representing the Paakantji, the Ngiyampaa,
and the Mutthi Mutthi Aboriginal Peoples
was provided to visit their country and
inspect the 21,000-year-old fossil footprints.
In addition, the first author was given access
to data previously collected by these
communities. 103 Kaurna People were
removed in the 1950s from a gravesite in
Karraundo-ngga and were housed in the
South Australian museum archives.
Approval was given from Uncle Lewis
Yerloburka O’Brien (Kaurna Elder) and the
South Australian Museum to inspect skeletal
remains of the author’s ancestors.
Limitations
This project examined skeletal
remains of Aboriginal People for possible
links to survival methods and techniques.
The skeletal remains examined were also of
relatively small number and the extent of
generalizability of the characteristics of
these bones to the greater Kaurna
community is unknown. The scope of this
research was restricted and not every aspect
or survival method was investigated.
Nevertheless, the authors believe these
findings make a valuable contribution to the
current understanding of survival of
Aboriginal People through one of the
toughest environmental conditions in human
history.
Results
Aboriginal Oral History
Interestingly, Aboriginal Australians
are sometimes undermined for not having
written documented history, but it may have
been oral story telling of factual events,
passed down unchanged for millennia which
contributed greatly to our survival. Many
Aboriginal tribes have been practising
survival education for millennia with
Dreaming stories, songlines, dance,
paintings, and carvings (Broome, 1982;
Charles, 2015; Isaacs, 1980). Many
Dreaming stories are about creation, but
many are also about teaching and learning as
some of this educating is designed to assist
survival. Many Dreaming stories are often
set in conflict between right and wrong,
jealousy, arguments, and disagreements
where listeners are able to learn from the
mistakes made by animals, creators, and
ancestors in these songlines, dance, stories,
and paintings (Broome, 1982; Charles,
2015). Traditional lifestyles were able to be
guided by Dreamtime stories, designed to
keep people safe and well (e.g., eating the
right foods and using medicines in the right
amount, prepared in the right way, and at the
right time of year (season), which is like
modern day health promotion) (Broome,
1982; Charles, 2015; Isaacs, 1980). There
are many Aboriginal oral Dreaming stories
which record that sea levels were much
lower than they are today (Barker et al.,
2001; Campbell, 1967). This is of course is a
true geological environmental fact about the
Australian continent and it is incredible that
this Aboriginal oral history has been shared
down approximately 320 generations
accurately for at least 8,000 years
(Campbell, 1967). These historic stories
International Journal of Indigenous Health, Vol. 15, 2020

were kept intact and unchanged, reflecting
precisely geological facts of the Australian
continent cooperated by many different
Aboriginal tribes in the same geographical
area (Barker et al., 2001). The ancestors of
the Gunaikurnai People, the traditional
owners of Gippsland area in Victoria,
Australia, have Dreaming stories of their
country extending further south which is
now covered by the ocean today (Fison &
Howitt, 1880; Fison & Howitt, 1880). The
Wurundjeri and “Wannadrung” (Note: name
may have been misinterpreted by colonists,
it may be Wadawurrung) tribes around what
is currently Port Phillip Bay in Victoria,
were reported as stating to the colonists that
there was previously plenty of kangaroo and
possum in the Port Phillip Bay, obviously
referring to a time when the sea level was
much lower (Barker, 1854). Similar
Aboriginal Dreaming stories were told by
nearby tribes of the Mornington Peninsula,
the Bunurong People, stating the low lands
(Port Phillip Bay) became flooded very
quickly following a violent storm and the
earth shaking (earthquake) (Rogers, 1966).
The Ngarrindjeri tribe of South Australia
also had oral history passed down
generations, of being able to walk to
Kangaroo Island, which is currently several
kilometres of the coast of South Australia
(Campbell, 1967) but the track to Kangaroo
Island would have been above sea level and
part of mainland Australia 8,000 – 10,000
years ago.
Refuges for Survival
There is research that suggests that
surviving the very harsh conditions of the
last ice age in Australia approximately
25,000 years ago was to seek refuge where
there was still fresh drinkable water, cover,
and plant life (Williams et al., 2013). It is
believed that all Aboriginal and Torres Strait
Islander people of Australia at that time
migrated to 11 distinct refugia (please see
Figure 3) and abandoned approximately
80% of the Australian landscape temporarily
because it was uninhabitable (Williams et
al., 2013). Although this theory seems
plausible, it should be noted that this study
could not investigate every part of the
continent or other possible populations and
refugia. Interestingly, based on Williams et
al 2013 theory, the main population centres
are several hundred kilometres inland or
possibly even thousands of kilometres
inland with sea levels being much lower at
that time, which seems counterintuitive to
survival considering the sources of
sustainability the ocean could provide, so
perhaps it was a fear of potential fast rising
oceans that led to inland settlement.

age in Australia (Williams et al., 2013).
Athleticism and Survival
Aboriginal Australians have
demonstrated great intelligence and
knowledge of our environment, which have
developed over the millennia (Watkins et al.,
2006; Webb, Cupper, & Robins, 2006).
Some of this ability to adapt to
environmental conditions has been an
evolutionary process (Webb, 2007) as a
knowledge and understanding of flora and
fauna would have been fundamental to
survival (Westaway, 2010). Physical ability
would have been paramount to survival and
International Journal of Indigenous Health, Vol. 15, 2020
10
integral to many Aboriginal cultures
(Robert, 1878; Taplin, 1879; Watkins et al.,
2006). Successful hunting would have
required great intellect, knowledge of the
fauna and the environment, but obviously
athleticism was essential for hunting (Grubb,
2011). Sahul had megafauna e.g., giant
kangaroo and emu 3 metres tall, and giant
wombat weighing over 1tonne. Although
approximately 85% of megafauna became
extinct about 50,000 years ago and most
disappeared 25,000 years ago, around the
time of the last ice age (Miller et al., 1999;
Roberts et al., 2001; Wroe & Field, 2006)
there is evidence of giant kangaroo and emu
surviving 21,000 years ago in Southern
Sahul, with paw prints found at Lake Mungo
in the Willandra Lakes World Heritage area
of NSW, Australia (Johnston, 2014).
Skeletal Anatomical Features
The Kaurna People of the Adelaide
Plains area in South Australia exhibit very
large nasal cavities (please see Figure 4)
which may have assisted with extremely
harsh ice age temperatures via warming very
cold air before entering the sinus passages,
throat, and lungs. These large nostrils would
have also limited entry of pathogens like
bacteria, fungi, and viruses (Barberán et al.,
2015; Dutkiewicz, 1978; Kellogg & Griffin,
2006) preventing infection(s) that may have
been life threatening, as these large nostrils
and hair would have captured pathogens
(Gonzalez-Martin, Teigell-Perez, Lyles,
Valladares, & Griffin, 2013). The Kaurna
People also exhibited a very broad and
pronounced brow and large eye sockets
useful for protecting the eyes in extremely
dusty, windy, and smoky (from bush fires)
conditions experienced 15,000 to 35,000
years ago, helping with visibility and
limiting eye infection(s) carried in dust
(Vismer, Marasas, Rheeder, & Joubert,
2002).
Figure 4
Skull of 60-year-old Kaurna Man
The skull and accompanying
mandible (please see Figure 5) of an
approximately 60-year-old Kaurna man
show the teeth to be in excellent condition
with no decay, which was the case with all
103 skeletal remains. This is an indication
that the Kaurna People, despite the difficult
environmental conditions, managed to
maintain a healthy, balanced diet, which
included adequate calcium levels, which is
known to improve bone (Fonseca & Ward,
2004) and strength (Kornegay & Thomas,
1981). These skeletal facial features and
bone health would likely have contributed to
the Kaurna Peoples survival in harsh
environmental conditions.

Figure 5
Mandible of 60-year-old Kaurna Man
Culture, Medicine and Treatments
Figure 6 contains the right and left
femur of a Kaurna man with the right femur
having a completely healed compound
fracture at the neck and shaft of the femur.
These types of injuries are very difficult to
heal, even for modern medical professionals
(Davidovitch, Jordan, Egol, & Vrahas, 2010)
and usually require fixation surgery
(Christie, Court-Brown, Kinninmonth, &
Howie, 1988; Mackenzie, 1971). Even with
the best modern surgical practices and
medicines, the rate of non-union and
necrosis with these compound fractures is
approximately 50% (Davidovitch et al.,
2010). The fact that this Kaurna man had
this injury completely healed is strong
evidence the Kaurna People were in good
health, had excellent knowledge of medicine
and therapies, with the capacity to heal our
community members, including from serious
medical emergencies. The sizable
calcification around the fracture suggests
this 60 year old man lived for at least 5 years
after the incident which caused the fracture
(likely to be a fall from a great height)
(Bourque, Gross, & HAll, 2004).
Figure 6
Compound Fracture of Right Neck and Shaft
of Femur
The fall from a great height may
have been while climbing a tree, perhaps for
hunting (possum) or finding a scoping
viewpoint, which the Kaurna and other
tribes were known to do regularly
(Lumholtz, 1889; Watkins et al., 2006). This
suggests that at least part of the Kaurna
survival strategy and perhaps part of our
success was regular tree climbing. However,
the most important evidence for the Kaurna
Peoples ability to survive is the fact that this
60year-old man survived such a severe
compound fracture of the neck and shaft of
the femur bone. This would have been a life
ending injury in many cases for people from
other cultures without knowledge of
treatment and therapies, certainly in the
harsh environmental conditions of the time.
For the Kaurna man who was in his 60s (an
Elder), to survive such a horrific injury
would have taken an extreme level of
support from the Kaurna community i.e.,
“community-strength”, certainly from many
members working together. This may be the
most important aspect of survival in these
harsh conditions -the culture of
“community-strength” within tribes- and
perhaps one of the earliest examples of
International Journal of Indigenous Health, Vol. 15, 2020
12
“community-care” which many Aboriginal
tribes are known for today (Berry et al.,
2010; Rowley et al., 2000). This Kaurna
man would have been in extreme pain, for a
very long period of time, and would have
been immobile for many months and would
have required constant support (Fox et al.,
2000). The recovery and rehabilitation from
such an injury would have required
knowledge of treatment, therapies, and
medicines for serious injury. Indeed, the
Kaurna People did have knowledge of
medicine to reduce pain, a shrub (pituri
plant) that produces an alkaloid which
contains nicotine (Langley & Dickinson,
1890). The Kaurna people administered
pituri in high doses to reduce pain (Langley
& Dickinson, 1890; Watkins et al., 2006;
Watson, 1983). Pituri would have been an
important medicine (narcotic) (Johnston &
Cleland, 1933) with a compound fracture,
which would have been incredibly painful.
The possibility to die from blood loss
would have been possible with an injury of
this type. However, if the person did not
bleed out, the possibility of contracting an
infection would have been the greatest risk
of a life-ending event. The Kaurna People
had knowledge of medicine to prevent
and/or treat infection and this would have
been paramount to this man’s survival.
Honey has been used by Aboriginal
Australians for thousands of years to treat
wounds and a variety of skin complaints,
including the Kaurna People (Boorn et al.,
2010). Although it had been dismissed by
many western medical professionals for
many years, it is now commercially
available for many purposes (e.g.,
MediHoney). MediHoney has been shown to
be effective for a variety of wounds
including those colonised or infected with
multi-resistant staphylococcus aureus
(MRSA) (Blaser, Santos, Bode, Vetter, &
Simon, 2007). Other studies showed
MediHoney to be effective against 58 strains
of staphylococcus aureus and 20 strains of
pseudomonas, and that honey dressing were
able to produce sterile wounds in 3-10 days
(Molan, 1999). It would have been likely
that this man’s wound would have been
treated with Honey as an antibacterial. Tea
Tree oil has also been used by many
Aboriginal Australian tribes as a disinfectant
against bacteria, fungi, and many other skin
problems (Carson, Hammer, & Riley, 2006;
Tong, Altman, & Barnetson, 1992),
including an effective agent against MRSA
(Caelli, Porteous, Carson, Heller, & Riley,
2000). This Aboriginal Australian traditional
medicine was also ignored by western
practitioners but is now commercially
available and widely used. The knowledge
of the properties of Tea Tree Oil, by the
Kaurna and other tribes and its abundance,
means it is very likely it would have been
used to treat this Kaurna man’s wound. The
Kaurna People would have had this man lay
in a bed of eucalyptus leaves and applied
some leaves directly to the wound site as an
antibiotic, as the leaves dry they will also
absorbed fluid and cushion the wound site.
There are many other traditional Aboriginal
medicines and treatments used for wounds,
pain, and injury that the Kaurna People
would have likely used (Watkins et al.,
2006). There was traditional knowledge of
medicines for inflammation that were widely
available to the Kaurna People and useful in
the treatment of this man (Devanesen,
2000). Many modern surgical techniques
involve surgical screws and internal braces
to the bone for such a fracture this Kaurna
man experienced (Christie et al., 1988). This
injury and accompanying wound would have
needed bracing of some form for it to heal
and reduce pain and allow union of the bone
(Herbert & Fisher, 1984) and the Kaurna
People did have exceptional knowledge of
human anatomy (Watkins et al., 2006). The
amount of sizable calcification tells us that
this man did in fact get back up and was
International Journal of Indigenous Health, Vol. 15, 2020
13
weight bearing for several years, which is an
incredible outcome and a credit to the
Kaurna Peoples knowledge and community-
strength.
Discussion
Aboriginal Oral History
The ancient historical geological
knowledge held by these Aboriginal
Peoples, of their country would have
assisted their survival. Knowing the
potential for massive sudden geological shift
and potential rise and fall of sea levels and
spread of disease would have likely
influenced their decisions about where to
live. Whether or not to have permanent
settlement at one site and committing great
time and resources in settling permanently
on the coast, or low-lying land. It is well-
documented that the Kaurna People of
Adelaide Plains in South Australia would
only have temporary dwellings and shift
from near the coast to the shelter of the hills
seasonally and main settlements that were
several kilometres inland. The Kaurna
People also spread out and lived in family
groups and clans (Watkins et al., 2006). This
regular rotation of dwelling was about flora
and fauna regeneration and disease
prevention i.e., leaving human and animal
waste behind to decompose. Interestingly
the permanent settlement at one single site,
and rapid gathering of the masses in
European cities led to the death of millions
from disease (Scott, Duncan, & Duncan,
1996). Perhaps the culture of nomadic
rotation of sites and dwellings of many
Aboriginal Australian tribes, living
separately of family groups and clans, but
supporting the entire tribe was based on
knowledge that was passed down from our
ancestors to look after mother earth, allow
regeneration, and preventing disease spread.
This was also based on preservation of time
and resources that could be lost with the
fluctuation of sea level and climate change.
This Aboriginal knowledge and culture of
community-strength would have contributed
to the survival of Aboriginal Australians.
Refuges for Survival
The mobility of these Aboriginal
People over such long distances to reach
refugia, through such incredibly difficult
environmental conditions, is staggering.
This mobility truly would have been a
“survival of the fittest” and certainly many
sacrifices would have had to been made to
reach these destinations. One can only image
the desperate journey to arrive at these
refugia. This is a clear demonstration of the
community-strength, adaptability, and
resilience of the Aboriginal People of
Australia. This process of mobility and
relocation may have embedded the need to
be mobile in some Aboriginal Australian
cultures, and why many Aboriginal tribes
did not invest too much time and resources
in building permanent structures and
dwellings and resisted cohabitation in one
large group (Watkins et al., 2006).
Athleticism and Survival
To successfully hunt these very large
and fast moving pre-historic animals it
would have taken great skill, knowledge and
athleticism by the Aboriginal People of this
time (Charles, 2017, 2018). Modern day
wombats have a top speed of 40km/hr,
kangaroos have a top speed of 70 km/hr, and
emu are one the fastest land birds on the
planet at 50km/hr (Bennett, 1987; Garland,
1983; Heglund, Fedak, Taylor, & Cavagna,
1982). There is no evidence for the running
speed of giant wombat, kangaroo and emu
but because of their size, and similar ratio,
they may have been even faster than their
modern relatives. However, regardless of
their speed, their size and strength alone
would have made hunting these giant
animals much harder and would have likely
International Journal of Indigenous Health, Vol. 15, 2020
14
take great athleticism and teamwork from
many members of the community. Despite
their possible great speed and known size of
these pre-historic animals, several studies
reported that Aboriginal Australians were
very successful hunters of megafauna
(Miller et al., 1999; Roberts et al., 2001;
Wroe & Field, 2006). This successful
hunting style, relying on community-
strength would have contributed to the
survival of Aboriginal Australians.
In conjunction with the required
knowledge of their environment, flora and
fauna, Aboriginal Peoples have evolved foot
structure and function that is conducive to
athleticism, which would have improved
hunting success and assisted their survival.
The first author has recently demonstrated
some aspects of foot and ankle morphology
and function that are highly prevalent in
modern day Aboriginal Peoples, including a
high arched foot type and reduced ankle
joint range of dorsiflexion (ankle equinus)
(Charles, 2015, 2017). The author found
ankle equinus was highly prevalent
especially in males and most commonly
affected the gastrocnemius muscle (Charles,
2015, 2017). This previous research
indicated that both the foot arch type and the
range of ankle joint dorsiflexion affected
plantar pressures, with a tendency to
increase the duration and degree of forefoot
loading (Charles, 2017, 2018), and this is
thought to have contributed to the
athleticism of Aboriginal Australians.
Although due to the cross-sectional nature of
these studies, the findings are not
generalizable to the total Aboriginal and
Torres Strait Islander population.
Although not generalizable, it is
possible both an ankle equinus and a high
arch foot type are an evolutionary
biomechanical development to increase
running speed and thereby improve hunting
ability and survival (Nigg, Cole, &
Nachbauer, 1993). The great running speed
of ancient Aboriginal Australians has been
documented at Lake Mungo in the Willandra
Lakes World Heritage area of NSW,
Australia (Johnston, 2014). Some of the men
running at Lake Mungo, are taking
approximately 25 steps to travel an
approximately 50 metres or if extrapolated
50 steps to travel 100m (Charles, 2018).
This stride pattern is similar to some of the
modern world’s high performance athletes
(Hanon & Gajer, 2009). If the Aboriginal
men at Lake Mungo are taking 50 steps to
travel 100m this would be an estimated sub
11 seconds to run 100m (Faccioni, 2016).
Using a pace calculator (Net, 2016) this is an
estimated top speed of 35km/h. It must also
be considered that these men were running
barefoot, in soft ground (mud), and likely
carrying a weapon(s) and/or other item(s)
(Charles, 2018). However, these calculations
of the ancient Aboriginal men running
100m, is an estimate based on an
extrapolation of a 50m run, and there is no
way of knowing if these men could have
maintained this stride pattern. This
athleticism would have been a key
component of survival of Aboriginal
Australians. Especially having to travel vast
distances to reach refuges and escape
unviable land and unliveable environmental
conditions (Williams et al., 2013). However,
athleticism and the ability run fast would
have only been part of the survival though
the last ice age.
Culture, Medicine and Treatments
It could be argued that the Kaurna
Peoples knowledge and use of traditional
medicines, therapies, and treatments would
have certainly contributed greatly to our
survival through difficult environmental
conditions.

Conclusion
The Australian continent has
experienced many environmental and
climatic changes over the millennia that
would have been an extremely challenging
for the Aboriginal People of Australia.
However, a period of two thousand years,
approximately 24,000 to 26,000 years ago
which would have been especially tough to
survive through. Navigating these extremely
harsh, rapidly changing conditions is an
incredible story of survival of Aboriginal
Australians. The findings of this
investigation suggest that Aboriginal
Australians survival methods were complex
and multi-faceted. There is evidence of an
evolutionary component to survival,
including facial features and biomechanics
that would have contributed to survival.
Aboriginal Australians have demonstrated
incredible endurance and fitness for mobility
and a strong “will” to survive. However,
perhaps our community mindedness and
community-strength is a very powerful tool
of resilience and resistance. Our culture,
knowledge, and understanding of flora and
fauna for nourishment and medicine and
other medical treatments was paramount to
the survival of Aboriginal Australians. The
benefits of living in family groups or clans
and avoiding mass cohabitation, knowledge
was passed down from ancestors and was a
key aspect of preventing the spread of
disease, seen in other continents like Europe.
The potential for rapid change to earth’s
environment and its impact on all
inhabitants experienced by Aboriginal
Australians is perhaps a lesson for modern
Aboriginal and non-Aboriginal people of our
earth.

... An abnormal windlass mechanism of the foot may contribute to increased foot pressure on the hallux and 1 st to 5 th metatarsal heads [28,29]. Therefore, the tendency to increase the duration and degree of forefoot loading also reflects what Charles suggested may contribute to Aboriginal Australians' athleticism [8,27,30]. A review of the PPDs between Indigenous Taiwanese and Australian aborigines showed there were still some different features, but both groups had higher midfoot plantar loads. ...

Background Although Indigenous Taiwanese are generally known for having excellent athleticism and balance abilities, the correlation between foot characteristics and balance abilities has rarely been discussed. This study aimed to explore the characteristics of plantar pressure profiles associated with foot posture and balance abilities among Indigenous Taiwanese. Material/Methods We recruited 165 Indigenous college students and 183 healthy age-matched students. Bipedal static plantar pressure distributions (PPDs) with arch index (AI) and centers of gravity balance were examined using the JC Mat. Foot posture was determined by estimating the rearfoot postural alignment. Results Indigenous Taiwanese in the study generally had low-arched feet with increased plantar loads at the medial (left: 1.21±0.43%; right: 1.20±0.46%) and lateral longitudinal arches (left: 24.51±5.26%; right: 24.45±6.64) (P<0.01) and the medial metatarsals (left: 21.78±3.81%; right: 22.19±3.91) (P<0.01). Footprint images illustrated pronounced cuboid and navicular collapses. Performances of balance abilities (left: 49.53±4.38%; right: 50.47±4.38) (P<0.01) and rearfoot postural angles (left: 1.37±1.25°; right: 1.32±1.17°) (P<0.05) were better than those of controls. Conclusions The feet in Indigenous Taiwanese had low arches and higher plantar loads at the medial and lateral longitudinal arches and medial metatarsals, while their centers of gravity were symmetrical and rearfoot posture was normal. These results may facilitate further studies on the relationship between foot characteristics, potential athleticism, and musculoskeletal injuries in Indigenous Taiwanese.
... While acknowledging the complexities inherent in Aboriginal traditions and the unavoidable unknowns involved in unpacking them, it seems likely that part of people's motivation for preserving their memories of these transformative events was to inform subsequent generations that such things periodically occur and, while disruptive, are survivable. This motivation is explainable by the importance of conveying all knowledge held by one generation to the next to optimize its chances of survival (Charles and O'Brien 2020;Ross 1986). With specific reference to postglacial sea-level rise and the trauma felt by coastal dwellers who experienced its consequences, there are clear lessons for today when many coastal peoples are feeling apprehension for similar reasons (Nunn 2020;Woodroffe and Murray-Wallace 2012). ...
... Indigenous Australians have a rich history on the Australian continent, estimated to be between 51,000 and 71,000 years old (Charles 2020). Concerted efforts from 1788 to colonise, annihilate, assimilate, and integrate Aboriginal and Torres Strait Islander communities resulted in the prevailing discourse of a single Australian community with Western values and perspectives (Lino 2017). ...

Culture is integral to Indigenous entrepreneurs, but how culture manifests in their entrepreneurial processes is understudied. This paper explores how Aboriginal entrepreneurs in Perth, Australia navigate cultural and commercial imperatives in their entrepreneurial practice. The study uses an interpretive lens and thematic analysis based on Altman’s hybrid economy model (HEM) to explore how ten Aboriginal entrepreneurs managed commercially viable enterprises while meeting their cultural obligations and aspirations. The focus is on the convergence of the customary and market economies and entrepreneurs’ experiences of navigating the hybridity of that space. We find that Aboriginal entrepreneurs iteratively assess the complementarity of cultural and commercial imperatives to protect their Indigenous identity while meeting business objectives. Cultural and commercial imperatives are navigated using context-dependent strategies. Strategies fall within fluid classifications of ‘high cultural–low commercial bias’, ‘high commercial–low cultural bias’, and an even consideration of both. We propose a contingency model to help explain Indigenous entrepreneurs’ approaches to navigating customary and commercial imperatives. This study contributes to knowledge of culture in Indigenous entrepreneurship by uncovering strategies Indigenous entrepreneurs can, and do, use to conduct business in ways culturally attuned to their indigeneity and situations.

English is not the first language for many Indigenous peoples, including Aboriginal Australians, and other minority groups. In Australia and many countries globally, health services are primarily delivered in English. Equity in health care can only be achieved if individuals are proficient in a language that they can understand. Interpreting services improves patient outcomes for minority language speakers. A comprehensive thematic analysis was used to identify key themes. When interpreter services were provided, patient care was improved for minority populations. The use of interpreters by Aboriginal Australians and the Aboriginal ‘voice’ in health care were missing. Language barriers are a major problem for minority language speakers in accessing health care, and inequitable treatment based on cultural, racial or ethnicity is common. In Australia, interpreter services for Aboriginal Australians in health care are under-utilised, and in many circumstances are unavailable. There is a severe lack of qualified interpreters globally in health care, particularly Aboriginal language interpreters, and there is a need for cultural competency training and cultural resources in health care settings. More Aboriginal interpreters are needed to provide a cultural lens and ‘two-way interpreting’ for Aboriginal Australians.

Abstract Introduction Health outcomes and life expectancy of Indigenous people throughout the world are far poorer than non-Indigenous populations. Emerging evidence from research shows that many social issues which impact on Indigenous peoples globally is linked to trauma over generations. This review explores literature about Indigenous people from around the world to seek interventions which have been successful in healing intergenerational trauma. Method To identify interventions that have been successful in healing intergenerational trauma amongst Indigenous populations globally, a systematic search strategy was conducted using keywords and synonyms related to the topic. Peer reviewed academic literature was sourced from four different databases i.e. Ebscohost, PubMed, CINAHL and Medline. Results 89 citations were found, 55 were identified as relevant, after duplicate copies were removed. Of these 55 papers, 23 met inclusion/exclusion criteria. Two additional papers from a reference lists were included and a total of 25 papers were analysed. A comprehensive critical appraisal of the literature was undertaken using three different appraisal tools. This review found that interventions which were successful in healing intergenerational trauma amongst Indigenous populations incorporated traditional cultural practices within their healing method(s). Discussion There was strong evidence that strengthening and reclaiming cultural identity enhances mental health disorders commonly experienced throughout Indigenous populations. Often non-Indigenous clinicians, although well intentioned, fail to address the needs of Indigenous people because they lack the understanding and awareness of Indigenous people’s culture. This review highlights benefits of blending Indigenous and Western approaches into healing intergenerational trauma and the concept of ‘Two-Eyed Seeing’. This concept acknowledges that each of our worlds has its strengths and if we respectfully and methodically accept these strengths, they can work together and effectively to bring about healing. Conclusion Healing from intergenerational trauma is not a straightforward process. Incorporating traditional healing methods assists in the development of cultural identity, which was found to be extremely important in the healing process. To address trauma effectively, clinicians need to acknowledge the historical impact from public policies by having a real understanding of our history.

Fusarium dimerum, typically a soil fungus, was isolated from an adult male suffering from a corneal ulcer following an injury to the eye. This fungus has not been described to cause human infections in South Africa and has not been recorded from soil, plant or organic material in this country. The macro- and microscopic characteristics of the isolate were found to be indistinguishable from described strains. Its authenticity was confirmed by comparing it to other human isolates from the eye obtained in the USA, thus rendering this the first report of F. dimerum from an eye infection in a human in South Africa.

For want of other secure evidence, the study of art in prehistoric societies normally amounts to looking at pictures, though there must have also been sound, and surely music. The long lithic tradition of central northern Australia permits a rare insight into another kind of prehistoric art, the meaning and aesthetic order that may lie behind a lithic industry. -Author

In 1880 the Norwegian ethnologist, zoologist and explorer Carl Lumholtz embarked on an expedition to Australia, with the purpose of observing the life and customs of the Australian Aborigines. This book focuses on his experiences while living for a year with a community in Queensland that had never previously come into contact with white people. 'Not only are many of the Australian Aborigines cannibals', says Lumholtz, 'but most of the tribes have not yet emerged from the Stone Age in the history of their development'. He goes on brilliantly to document a complex and fascinating society. Containing detailed maps to illustrate the explorer's travels and many images, the book also includes informative appendices outlining Australian history, geology, flora and fauna. First published in 1889, Lumholtz's classic account of the events and practices he witnessed retains the power to shock, educate and entertain the modern reader.

The population history of Aboriginal Australians remains largely uncharacterized. Here we generate high-coverage genomes for 83 Aboriginal Australians (speakers of Pama-Nyungan languages) and 25 Papuans from the New Guinea Highlands. We find that Papuan and Aboriginal Australian ancestors diversified 25-40 thousand years ago (kya), suggesting pre-Holocene population structure in the ancient continent of Sahul (Australia, New Guinea and Tasmania). However, all of the studied Aboriginal Australians descend from a single founding population that differentiated ∼10-32 kya. We infer a population expansion in northeast Australia during the Holocene epoch (past 10,000 years) associated with limited gene flow from this region to the rest of Australia, consistent with the spread of the Pama-Nyungan languages. We estimate that Aboriginal Australians and Papuans diverged from Eurasians 51-72 kya, following a single out-of-Africa dispersal, and subsequently admixed with archaic populations. Finally, we report evidence of selection in Aboriginal Australians potentially associated with living in the desert. © 2016 Macmillan Publishers Limited, part of Springer Nature. All rights reserved

A number of models, developed primarily in the 1980s, propose that Aboriginal Australian populations contracted to refugia e well-watered ranges and major riverine systems e in response to climatic instability, most notably around the Last Glacial Maximum (LGM) (23-18 ka). We evaluate these models using a comprehensive continent-wide dataset of archaeological radiocarbon ages and geospatial techniques. Calibrated median radiocarbon ages are allocated to over-lapping time slices, and then K-means cluster analysis and cluster centroid and point dispersal pattern analysis are used to define Minimum Bounding Rectangles (MBR) representing human demographic patterns. Exploring data be-tween 25 and 12 ka, we find a refugia-type hunter-gatherer response during the LGM (23-18 ka) and again during the Antarctic Cold Reversal (ACR) (14.5-12.5 ka), with expansion in the intervening period. Several refugia persist between 25 and 12 ka, including (by Interim Biogeographic Regionalisation for Australia areas) Gulf Plains/Einasleigh Uplands, Brigalow Belt South, Murray Darling Depression, and Tasmanian Central Highlands. Others appear sporadically through the same period. These include South Eastern Highlands, NSW South Western Slopes, Sydney Basin, Warren, Murchison, Gascoyne, Central and Northern Kimberley, Ord Victoria Plain, Arnhem Plateau, MacDonnell Ranges and Central Ranges. The Pilbara may also have been a refugium during the LGM, but geospatial results are problematic for this region. Areas devoid of human activity ('barriers') include the main desert regions, especially in the south and west of the continent, although some of these may be the result of an absence of archaeological fieldwork. Point dispersal pattern analysis indicates a reduction in occupied territory of nearly 80% during the LGM. A reduction of close to 50% was also evident during the ACR. A large number of the refugia were in close proximity to glaciated areas during the LGM, and probably benefitted from increased summer snowmelt along the major river systems. The remaining refugia are likely the result of a range of local environmental and resource factors. We identify areas for future research, including a focus on regional studies to determine possible cryptic or idiosyncratic refugia emerging in phlyogeo-graphic studies.

The mystery of vanishing species has occupied the minds of palaeontologists and neontologists for more than a century. In more recent times the exponential growth of the human population with accompanying habitat destruction and shrinking biodiversity is an inescapable reality. Could humans have also been responsible for the extinction of the ice-age megafauna? Martin & Wright (1967) attributed the extinction of North American megafauna to the spread of humans. It was a theme echoed in Australia by Merrilees (1968) in his keynote paper 'Man the destroyer' and revisited by Flannery (1994) in 'The Future Eaters'. A confounding variable in the Ice-age extinctions has been the role of climate. Contemporary research into past climates is providing temporal resolution approaching biological time scales and now sheds new light on a number of single cause hypotheses. Chris Johnson's book, 'Australia's Mammal Extinctions: a 50,000 year history', is both timely and comprehensive. It aims to bring a scientific approach to a multidisciplinary problem. The author outlines the importance of multiple working hypotheses and refutation in arriving at a best fit explanation. An approach perhaps obvious to readers with a scientific background but all too often missed or misunderstood in an adversarial society. Whether you agree or disagree with Johnson you have a framework in which to test his interpretations. The structure of the book invites debate not blind acceptance, indeed the author's bias is clear and the conclusions in many sections are built on so many 'ifs', 'mays' and 'mights' that one can lose count. Paradoxically this is a strength not a weakness for it provides not only an endless array of research questions but should also sound a cautionary note to those who would blindly invoke the conclusions to frame management policy. Johnson has surveyed an impressive body of literature in many disparate fields and this well written and referenced book should appeal to both the general reader as well as specialists seeking a broader context for their own research. What will not be so apparent to the general reader are the assumptions underpinning the interpretation of evidence from the sub-discipline areas. The book is well illustrated with some elegant paintings of extinct mammals.
