REPORT
Climate Response by the Ski Industry: The Shortcomings
of Snowmaking for Australian Resorts
Catherine Marina Pickering, Ralf C. Buckley
Received: 10 December 2008 / Revised: 17 May 2009 / Accepted: 18 November 2009 / Published online: 3 June 2010
Abstract Skier numbers, and revenues for the multi-bil-
lion-dollar ski industry, are highly sensitive to snow cover.
Previous research projected that under climate change,
natural snow cover will become inadequate at 65% of sites
in the Australian ski resorts by 2020. Resorts plan to
compensate for reduced snowfall through additional
snowmaking. For the six main resorts, however, this would
require over 700 additional snow guns by 2020, requiring
*US $100 million in capital investment, and 2,500–
3,300 ML of water per month, as well as increased energy
consumption. This is not practically feasible, especially as
less water will be available. Therefore, low altitude ski
resorts such as these may not be able to rely on snow-
making even for short-term adaptation to climate change.
Instead, they are likely to seek conversion to summer
activities and increased property development.

INTRODUCTION
Anthropogenic climate change is already affecting the
climate of mountain regions worldwide, and much larger
effects are projected (Intergovernmental Panel on Climate
Change 2007). This includes higher temperatures and
reduced precipitation for many alpine regions (Intergov-
ernmental Panel on Climate Change 2007), including those
in Australia (Green and Pickering 2002,2009; Hennessey
et al. 2003,2008; Nicholls 2005). Snow-based tourism is a
major industry (Scott and McBoyle 2007), with the Aus-
tralian ski resorts worth *US $725,000,000 in 2005
(NIEIR 2006). Reduced snow cover will affect most snow-
based recreation, including skiing, snowboarding,
snowshoeing, tobogganing and snowmobiling (Scott and
McBoyle 2007). These effects have been examined in a
range of Northern Hemisphere resorts (Scott and McBoyle
2007) including the Swiss Alps (Ko
¨nig and Abegg 1997;
Elsasser and Messerli 2001), Austria (Breiling and Char-
amza 1999), Sweden (Moen and Fredman 2007), the whole
of the European Alps (Agrawala 2007), the north-eastern
USA (Scott et al. 2008), Quebec (Scott et al. 2007), Ontario
(Scott et al. 2003) and Japan (Fukushima et al. 2002).
There is much less research in the Southern Hemisphere,
including the Australian Alps, the main ski tourism desti-
nation in Australia (Hennessey et al. 2003,2008; Galloway
1998). In this article, we examine the impact of climate
change on Australian ski resorts, focussing on their
capacity to utilize snowmaking to reduced natural snow
cover.
METHODS
We analyse the implications of potential climate change for
ski resorts in Australia using publicly available informa-
tion. Climate data, projections of climate change, visitation
and financial data for resorts are much more limited in
Australia than in Europe (Breiling and Charamza 1999;
Sieva
¨nen et al. 2005; Agrawala 2007; Moen and Fredman
2007; Gonseth 2008; Vanham et al. 2008), North America
(Scott et al. 2008; Shih et al. 2009) or Asia (Fukushima
et al. 2002). Only four official snow courses are used for
modelling snow cover in Australia, and measurements are
taken only once every 2 weeks. Available data thus do not
always cover the full period that snow is on the ground, and
data are often missing. Even basic temperature data are
limited, with few weather stations above 1,300 m consid-
ered to have reliable long-term ([20 years) data sets

(Hennessey et al. 2003,2008). Ski resorts in Australia
generally treat visitation data, income, expenditure, water
and power consumption, and even snow-cover data as
commercially confidential. This applies particularly for the
privately-owned ski resorts in the state of New South
Wales (NSW). Ski resorts in the state of Victoria (Vic)
provide some relevant information in their annual reports
(Alpine Resorts Co-coordinating Council 2007,2008),
because of compulsory public reporting requirements.
Our approach is as follows. Firstly, we assessed the
effects of variation in natural snow cover on skier numbers
over the nine ski seasons. Secondly, we compiled data on
current snow-making by Australian ski resorts, including
the value of current snow-making infrastructure. The
principal source of such data is a recent report which
models the impacts of climatic warming on snow condi-
tions, with detailed projections of changes in natural snow
cover (Hennessey et al. 2003,2008). Thirdly, we calculate
the number of snow guns, the water requirements, and the
costs of snow guns and associated infrastructure for each of
six Australian ski resorts under one 2020 climate change
scenario. The infrastructure comprises pumps, pipes and
water storage facilities. We calculated water requirements
by converting snow volumes to water volumes using the
same methods as in previously published climate-model-
ling calculations (Hennessey et al. 2003,2008). Our esti-
mates for the average costs of snow guns and associated
infrastructure were calculated using June 2008 values, from
the reported investment of US $13 million for 99 snow
guns (Australian Ski Areas Association 2008). Australian
dollar values (AUD) were converted to United States
dollars (USD) at the exchange rate applying at that time,
namely 0.8.
SKIING IN AUSTRALIA
In Australia, regular snow is limited to the Australian Alps
and small areas in Tasmania (Fig. 1). Only 5,000 km
2
(0.15%) of the mainland regularly experiences any snow
cover persisting for more than a month each year, and
\3km
2
of this lies within existing ski resorts. There are 10
main resorts currently operating in the Australian Alps
(excluding Tasmania), ranging from 1,520 to 2,054 m
in altitude (Table 1). Revenues in 2005 totalled *US
$725 million (AU $906 million), from just under three
million visitor days (Australian Ski Areas Association
2008). Most of the Australian Alps lies within national
parks, and the resorts are all within or adjacent to these
parks. The ski season extends nominally between two
particular public holidays, a period of 113-120 days, but,
the actual season is much shorter, as outlined below.
Snow cover in Australian ski resorts is generally much
lower than in Northern Hemisphere resorts, which are at
higher altitudes or higher latitudes (Ko
¨nig 1998; Fukushi-
ma et al. 2002; Moen and Fredman 2007; Scott and
McBoyle 2007; Scott et al. 2008). This applies whether
snow cover is measured using duration, maximum depth or
cumulative snow cover for the whole season. The mean
maximum snow depth for the four main snow courses in
the Australian Alps during the last 55 years ranged from
*0.55 m at 1,460 m altitude, to *2.2 m at 1,830 m

altitude (Hennessey et al. 2003). Corresponding figures for
natural snow cover at ski resorts in Victoria ranged from
*40 cm at 1,234 m altitude to *1.45 m at 1,845 m alti-
tude (Australian Ski Areas Association 2008). The mean
number of days with 20 cm or more of natural snow, over
the past 10 years, ranged from 38 days at the lowest of
these six resorts, to 113 days at the highest (Australian Ski
Areas Association 2008). Corresponding figures for 30 cm
cover range from 4 to 107 days (Alpine Resorts Co-coor-
dinating Council 2007,2008). Even with snowmaking, the
number of days with 20 cm or more of snow only increased
slightly. During 2007, there were 42 such days at the
lowest altitude resort and 111 days at the highest. Mean
maximum snow depth is less than 1.5 m at any of these
resorts, even with snowmaking.
There exists a very close and statistically significant
(P=0.034) relationship between the cover of natural
snow and the number of visitors at these resorts (Fig. 2).
The numbers of winter visitor days for all resorts open in
each year in NSW and Victoria increased linearly with
cumulative daily snow depth at the highest-altitude snow
course. On average, during 2000–2008 inclusive, every
additional metre of cumulative natural snow cover was
associated with *3,000 additional winter visitor days. Not
only are skiers highly sensitive to annual variation in nat-
ural snowfall, but this sensitivity is increasing. In 1996,
when skiers were asked how they would react to reduced
natural snow cover, 37% said they would ski elsewhere,
and a further 37% that they would ski less often (Ko
¨nig
1998). In 2007, however, only 16% said that they would
travel overseas to ski, and 74% said that they would ski less
often (Pickering et al. 2009).
According to ski-resort CEO’s and other industry com-
mentators (Bicknell and McManus 2006; Department of
Sustainability and Environment 2004), the Australian ski
resorts nevertheless see snowmaking as their principal
response to low natural snow in the future. In the following

sections, therefore, we examine what this involves and how
feasible it may be.
SNOWMAKING
In order to improve snow cover, resorts rely on: snow-
making; snow grooming and farming; and the modification
of the underlying terrain, known euphemistically as su-
pergrooming (Scott and McBoyle 2007; Australian Ski
Areas Association 2008; Pickering and Hill 2003). Snow-
making involves pumping stored water into the air under
pressure, often with a nucleating agent, when wet bulb
temperatures are below -2.5°C (Australian Ski Areas
Association 2008). In Australia, snowmaking is used
principally to provide snow cover at the start of the season,
to maintain cover on high use areas at lower altitudes, and
to extend the season at the end (Australian Ski Areas
Association 2008). Over the past 15 years, areas serviced
by snowmaking infrastructure within the larger Australian
ski resorts have increased by a factor of 2.75 times, from
*120 to *330 ha (Table 1). Even with this increase,
however, snowmaking areas cover \12% of the total ski-
able area in the resorts, which is 2.8 km
2
. Corresponding
proportions in European resorts range from 11.5% in the
German Alps, to 80% in the French Alps (Agrawala 2007;
Vanham et al. 2008; Gonseth 2008). In North America, the
proportions are higher still: 50–100% in some parts of
Canada (Scott et al. 2003) and 62–98% in the USA (Scott
and McBoyle 2007).
Snowmaking infrastructure differs considerably between
the various Australian resorts. There are differences in the
numbers, sizes, types and locations of water reservoirs,
pipes, compressors and snow guns (Australian Ski Areas
Association 2008). Snow guns themselves are only one
component of the capital costs of snowmaking infrastruc-
ture. Ski runs at lower altitude need considerably more
guns and water than those at higher altitude [Table 2, data
from Hennessey et al. (2003,2008)]. Lower altitudes
receive less natural snowfall, and have fewer nights that are
cold enough for snowmaking (Hennessey et al. 2003,
2008), so the resorts need to operate more guns simulta-
neously to compensate. In practice, therefore, snowmaking
is subject to significant physical, economic and environ-
mental constraints. In the following sections, we examine
how these constraints will affect the ability of Australian
ski resorts to make more snow under a changing climate.
CLIMATE CHANGE PROJECTIONS
The Australian Alps are at particular risk from climate
change. The most recent projections (Hennessey et al.
2003,2008) indicate that by 2020, just over a decade from
now, mean annual temperatures will increase by up to
1.0°C, and precipitation will decrease by up to 8.3%. We
refer to this projection as the ?1°C scenario. During
Australia’s usual skiing months from June to the end of
September, mean temperatures at ski resorts range from
0.7°C at 1,701 m altitude down to -1.55°C at 1,957 m
altitude, considerably warmer than most resorts in Europe,
Japan and North America (Hennessey et al. 2003,2008).
The projected 1°C rise in annual average temperatures will
thus have substantial effects both on natural snow cover
and on the number of nights suitable for snowmaking
(Hennessey et al. 2003,2008).
Current evidence indicates that temperatures are already
increasing, and winter snow cover is already decreasing,
particularly at higher altitudes (Green and Pickering 2002,
2009; Hennessey et al. 2003,2008; Nicholls 2005). Under
the ?1°C scenario, the area experiencing at least 60 days
with at least 1 cm of natural snow would decrease by 60%
(from 1990 to 2020). This would reduce the period with at
least 1 cm of natural snow cover to below the key threshold
of 60–70 days per year at the lower altitude sections of
almost all the ski resorts concerned [Fig. 3, data from
Hennessey et al. (2003)]. The projected number of days
with at least 1 cm snow cover under the ?1°C scenario has
been modelled at 20 individual locations within the resorts.
Only seven of these, i.e. 35%, are expected to retain
70 days or more with 1 cm or more of natural snow cover
by 2020 [Fig. 3, data from Hennessey et al. (2003)]. Two
more will have 60-70 days, and 11 are likely to have
\60 days snow cover per year under climate change sce-
narios as currently projected.
SNOWMAKING AS A RESPONSE
In order to make enough snow to keep existing runs skiable
under the ?1°C scenario, ski resorts in the Australia Alps
would need to increase both the number of snow guns and
how often they are used (Table 2). This means they would
need more water and more electricity to keep runs open,
with the greatest increases in the lowest altitude resorts. At
higher altitudes, the yield of snow from each gun is higher,
because there are more nights when it is cold enough for
the gun to operate. At lower altitudes, there are fewer
nights suitable for snowmaking, so more guns are needed
to produce the same volume of snow. In addition, at lower
altitudes, the total volume of snow needed to provide
adequate cover is greater than at high altitudes, because
there is less natural snow and because more snow melts and
evaporates. At present, the highest resort in the Australian
Alps operates only one gun per ski run, consuming
15,535 m
3
of water per season and yielding 38,838 m

snow per run per season (Table 2). The lowest resort, in
contrast, uses 15 guns per ski run, consuming a total of
27,084 m
3
per season of water and yielding 67,710 m
3
of
snow per run per season.
Under the ?1°C scenario, there will be: less natural
snow; fewer nights and fewer hours per night sufficiently
cold and humid for snowmaking; and increased rates of
evaporation and ablation, i.e. loss of snow and ice from
existing cover (Hennessey et al. 2003,2008). Under the
?1°C scenario, to achieve the same overall level of snow
as currently, these six resorts would need to install a further
1.7–45 guns per run, and increase total water consumption
by factors of around 23–62% per run. The lowest altitude
resort would need [25 times as many new guns per run as
the highest, for the reasons outlined above. The highest
resort is also the largest, however, with more runs, more
snowmaking facilities and more visitors than the lowest.
Total water consumption would thus increase by 42% at
the highest resort but only 23% at the lowest (Table 2). For
these six ski resorts in aggregate, maintaining sufficient
snow cover under the ?1°C scenario would require a fur-
ther 726 snow guns in total (Table 2).
INVESTMENT IN INFRASTRUCTURE
The cost of installing snow guns varies considerably,
depending on the type and location of the guns and the
cost of piping, water storage facilities, pumps and control
systems. Estimates of average costs can be derived from
recent snowmaking expenditure by ski resorts. The resorts
recently installed a total of 99 snow guns and associated
infrastructure at a cost of US $13 million (Australian Ski
Areas Association 2008). Therefore, the cost of a single
snow gun and associated infrastructure is of the order of
US $131,000 in 2008. Using this figure, the total invest-
ment in current snowmaking infrastructure at the six
resorts can be estimated to be around US $82 million.
This compares to investments of around US $61 million
on snow making in the French Alps, US $1,005 million in
Austria, and US $415 million in Switzerland (Agrawala
2007).
If snowmaking is used to offset losses in natural snow
cover under climate change, then the investment in addi-
tional snowmaking infrastructure as calculated above
would be US $95.2 million (in 2008 dollars) over the next
decade, bringing the total to more than double the current
figure. Even without considering the increased costs of
running the snow guns, this represents an additional cost of
*US $5 per person per day, based on the average visita-
tion of 1.67 million winter visitors days per season to these
six resorts. If passed on directly to visitors, then this would
produce a noticeable but not prohibitive increase in prices.
This estimate does not include the increased cost of power
to run the snow guns, which would lead to further price
increases. Financial aspects, however, are not the only
barrier. There are also significant physical constraints,
notably the availability of water. These are considered
below.
WATER AVAILABILITY AND ENERGY COSTS
With the proposed increase in snowmaking under the ?1°C
scenario, by 2020, these six ski resorts would consume a
total of 10,000 ML of water over a 3–4 month season
(Table 2), i.e. 2,500–3,300 ML per month. For compari-
son, the average monthly water consumption in Canberra,
the Australian capital and the closest large city to the
resorts is about 2,800 ML per month (ACTEWAGL 2008).
Would such a huge increase for the resorts actually be
feasible?
There prevails a strong competition from various
industry sectors for water from the Australian Alps. In
addition to tourism, water is in heavy and increasing
demand from irrigated agriculture, urban residential use,
power generation and a variety of other industrial uses.
Widespread droughts in south eastern Australia have
demonstrated clearly that water resources are a limiting
constraint on the regional economy. Under these circum-
stances, government and private water resources agencies
have two principal options: quotas or charges. Either way,
water prices are likely to increase to a level set by the
sector with the highest economic or political yield. Water

for snowmaking will therefore become more expensive,
perhaps considerably so.
Water costs for ski resorts will be reduced if the
resorts can capture and re-use snowmelt runoff, and use
recycled water from accommodation and other facilities.
Resorts are indeed starting to use these approaches, but
they are unlikely to substitute completely for the con-
sumption of raw water from natural riverflow. Most of
the runoff from the Australian Alps is already captured
through a giant series of dams and diversions associated
with the Snowy Mountains Scheme, which generates
hydroelectric power and supplies irrigated agriculture in
drier inland regions. The Australian Alps lie largely
within national parks, and there are minimum ecological
streamflow requirements for conservation. Therefore,
resorts are unlikely to be able to obtain the large volumes
of water for snowmaking except by purchasing water in
competition with other sectors. Even then, they may not
be able to access enough water, as there is limited
waterflow in creeks to harvest. Water catchments in the
ski resorts in the Australian Alps are small relative to
those of Europe and North America.
Snowmaking requires electricity to operate pumps and
compressors, and energy costs will consequently increase
in line with water consumption (Agrawala 2007). In addi-
tion, energy prices in Australia are expected to increase
steeply for a variety of reasons, including decreased
availability of water for hydroelectric power generation,
and a variety of climate change mitigation measures. This
will further decrease the financial viability of snowmaking
as a strategy for ski resorts to adapt to climate change.
DISCUSSION AND CONCLUSIONS
Current projections of short-term climate change indicate
that ski resorts in the Australian Alps will face several
simultaneous pressures over the next decade. If current
climate trends continue as projected under the ?1°C sce-
nario, many ski areas would fall below the minimum
financially viable threshold if they were to rely on natural
snowfall alone. Accordingly, they plan to increase reliance
on snowmaking. Our calculations here, however, show that
ski resorts may simply be unable to gain access to the
additional volumes of water which would be required; and
if at all they could, the costs of additional infrastructure,
water and electricity are likely to render ski operations
uneconomic. Their financial situation could also be exac-
erbated if higher prices and lower snow quality lead many
of their current clients to travel overseas to ski, or simply
ski less often.
The financial sensitivity of the Australian ski industry to
these effects can be gauged from the consequences of low-
snow years. Effectively, predicted climate change simply
equates to a higher proportion of low-snow years. During
the 2006 ski season, natural snowfall was at a 20-year low
(Green and Pickering 2009; Alpine Resorts Co-coordinat-
ing Council 2007), and the net incomes of ski resorts fell
heavily as visitor numbers decreased and operating costs
increased (Mt Baw Baw Alpine Resort Management Board
2007; Falls Creek Alpine Resort Management Board 2007;
Mt Hotham Alpine Resort Management Board 2007;Mt
Buller and Mount Stirling Alpine Resort Management
Board 2007). For some resorts, this resulted in significantly
reduced profits, while for others it resulted in a loss (Mt

Australia’s major ski resorts are operated by corporations
with a history of significant profits, a number of parallel
income streams, and large net financial assets, and so they
were able to weather the 2006 season relatively unscathed.
A series of such years in succession, however, could have
more serious financial consequences.
We reach these conclusions from publicly available
documents. If we can recognise the risks facing these
resorts and the shortcomings of snowmaking as the sole
response, then the ski resorts can certainly do likewise. In
fact, therefore, it seems highly unlikely that they are in
reality relying solely on snowmaking as a response to cli-
mate change. It seems more probable that whilst resorts do
indeed plan to increase snowmaking in the short term, they
may have other strategies for the longer term and may be
focussing on snowmaking principally as a political tool: to
gain access to additional water; to gain taxpayer-funded
government subsidies for new infrastructure and cheap
electricity; and to lobby for access to higher-altitude terrain
inside protected areas. In addition, it seems highly likely
that the higher-altitude resorts anticipate that their lower-
altitude competitors will be unable to continue operating
ski lifts, so that in the short term, visitor numbers at the
higher-altitude resorts may be boosted by a contraction of
the industry.
The most likely scenario, however, is that the Australian
ski resorts plan to follow the example of their North
American and European counterparts, and move their
business models away from winter ski-lift tickets as the
principal source of revenue, to year-round resort-based
activities and a focus on residential property sales and
associated retail activities. It appears that this shift has
already occurred at a number of European and North
American resorts (Scott and McBoyle 2007; Agrawala
2007; Scott et al. 2008), even though they have longer and
more reliable ski seasons than those of their Australian
counterparts.

Visitor data indicate that many people visit the Austra-
lian Alps National Parks in summer as well as winter
(NIEIR 2006). Australia’s ski resorts are starting to capi-
talise on this. Currently, some of the major resorts close
down almost completely in summer. The key reason is that
since most of these resorts are inside or surrounded by
protected areas, they have limited legal scope for on-site
residential development, and most of their skier accom-
modation is in gateway towns outside the parks at lower
altitudes. These gateway towns do indeed provide tourist
accommodation and activities year-round, with high visitor
numbers in summer as well as winter. A small number of
the ski resorts such as those at Thredbo in NSW and Falls
Creek in Victoria do have accommodation on site and can
offer a variety of activities in summer. These resorts have
successfully made the transition to four-season mountain
resorts. Arguably, it is only planning restrictions on further
residential developments which limit their transition to
mountain resort-residential towns comparable to Aspen,
Banff or Chamonix. Residential developments close to ski
areas, such as Dinner Plains near Mount Hotham in Vic-
toria, seem to have been highly successful in economic
terms (Buckley et al. 2006).
We conclude, therefore, that whilst ski resorts are likely
to promote increased snowmaking as a short-term solution
to climate change, this is in fact financially realistic only
for the higher-altitude resorts. Those at lower altitude are
likely to lobby strongly to increase access to land for res-
idential subdivision and for high-cost summer tourist
activities such as golf and watersports. We can, therefore,
foresee a period of increasing contention between the
corporations which run ski resorts, and the public agencies
responsible for protected areas and water supplies. What-
ever the precise outcome, it seems likely to involve
increased social, economic and environmental costs. The
Australian ski industry thus provides an example of the
many indirect mechanisms by which human social
responses to climate change can generate more complex
impacts beyond the direct biophysical consequences of
changing temperatures and precipitation.
