Why Mount Kosciuszko is famous
Kosciuszko is the roof of mainland Australia, and that is the whole story of its fame: a 2,228 m summit on an old, worn-down range rather than a dramatic peak. It owes its place on many climbers' lists to the Seven Summits. When the American businessman Dick Bass became the first person to stand on the highest point of every continent, finishing on 30 April 1985, he counted Kosciuszko as Australia's summit. The rival list proposed by Reinhold Messner takes the wider continent of Australia-Oceania and replaces it with Puncak Jaya (Carstensz Pyramid, 4,884 m) in New Guinea. The Canadian Pat Morrow completed the Carstensz version in 1986 and was the first to finish both lists. Many Seven Summits climbers still walk up Kosciuszko anyway: it takes an afternoon.
It is also not the highest point of Australian territory. That is Mawson Peak (2,745 m), an active volcano on remote Heard Island in the Southern Ocean. Kosciuszko is the highest point of the mainland, and its neighbour Mount Townsend (2,209 m) is the second highest.
Where it is and how to get there
The mountain stands on the Main Range of the Snowy Mountains, part of the Great Dividing Range, in the south of New South Wales near the Victorian border. The nearest city is Canberra; Sydney is about 500 km to the north. The usual base is the ski resort of Thredbo (village at about 1,365 m), reached on the Alpine Way through Cooma, Berridale and Jindabyne; coaches run from Cooma and Jindabyne. The other base is Charlotte Pass (1,755 m) at the end of Kosciuszko Road.
Thredbo's Kosciuszko Express chairlift, a quad built in 1990 (called the Crackenback Express until 2000), is 1,860 m long and rises 560 m to its top station at 1,925 m, near the Eagles Nest restaurant. The ride takes about 15 minutes. Ticket prices and summer operating hours are set by the resort each season, so check them before you go. If you prefer to walk the whole way, the Merritts Nature Track climbs 4 km from Thredbo Village to the top of the chairlift, a steep 2–3 hours uphill.
Routes to the summit
Kosciuszko Walk from Thredbo (the standard route). NSW National Parks lists this as a 13 km return walk of 4–5 hours, grade 3. It starts at the top of the chairlift (1,925 m), so the net climb is only about 300 m. The path crosses the granite tors of the Ramshead Range, passes a lookout over Lake Cootapatamba (2,048 m), the highest lake in Australia, and joins the old summit road at Rawson Pass. From there a final 1.4 km path leads to the summit. Long stretches are on a raised steel-mesh walkway built to protect the alpine vegetation; the mesh can be sharp, and running on it is not permitted.
Summit walk from Charlotte Pass. The old Summit Road was closed to private vehicles in the 1970s (1976 or 1977, depending on the source) and is now a wide gravel track: 7.6 km to Rawson Pass and then 1.4 km on foot to the top, 18.6 km return in 6–8 hours, grade 3. On the way it passes Seaman's Hut, a stone emergency shelter built in 1929. Mountain bikes and fat bikes are allowed between Charlotte Pass and Rawson Pass, where there are bike stands; the last 1.4 km is foot only.
Main Range Walk. The classic long day walk is a 22 km loop from Charlotte Pass, 7–9 hours, grade 4. It crosses the young Snowy River — the river of Banjo Paterson's 1890 poem The Man from Snowy River, which rises on the slopes of Kosciuszko — and climbs past Hedley Tarn and the glacial Blue Lake onto the Main Range, follows the ridge to Kosciuszko and returns along the Summit Road. Glacial lakes such as Club Lake and Lake Albina lie in cirques below the ridge.
Hannel's Spur. For a real climb, the 15.5 km Hannel's Spur Track comes up from the western side near Geehi, the direction from which Strzelecki approached in 1840. With about 1,800 m of ascent it is officially the biggest vertical climb on an Australian walking track.
Multi-day. The Snowies Alpine Walk links the alpine resort villages in a 56 km, four-day route across the high country.
Permits, fees and rules
No permit or guide is needed to walk to the summit. Kosciuszko National Park charges a vehicle entry fee. As of the 2025–2026 seasons, NSW National Parks lists $29 per vehicle per day in the winter peak (from the June long weekend to the October long weekend) and $17 per vehicle per day for the rest of the year; motorcycles pay $12 and $7. Annual passes and a five-day Short Breaks Pass ($68, not valid in winter) are sold online and at visitor centres. Chairlift tickets are bought separately from Thredbo. Stay on the tracks and walkways: the alpine plant communities are small and easily damaged.
When to go and weather
The walking season is roughly November to May, once the snow has melted; the tracks are snowbound from June to October. Early summer is the time for alpine wildflowers. Lake Cootapatamba is usually frozen from June to October or November. Weather on the Main Range changes quickly and can be extreme at any time of year: carry warm and waterproof layers even on a sunny summer morning. Winter storms bring winds up to 150 km/h and as much as a metre of snow in 24 hours. The weather station at Charlotte Pass holds Australia's lowest recorded temperature outside Antarctic territory, −23.0 °C on 28 June 1994.
In winter Kosciuszko is a cross-country ski or snowshoe objective. From Thredbo there are no snow poles marking the route, so you need navigation skills; Charlotte Pass is reached in winter only by oversnow transport from the Perisher Skitube terminal.
Water
There is no drinking-water supply on the summit routes, and NSW National Parks asks walkers to bring their own water. Fill your bottles in Thredbo Village before taking the chairlift, or in Charlotte Pass on the northern side. For the 13 km Thredbo walk carry 1.5–2 litres per person, more on a hot day; for the Main Range loop take 2–3 litres. The alpine area has streams, tarns and the upper Snowy River, but with so many visitors treat any natural water before drinking. Do not count on the toilet block at Rawson Pass for drinking water.
Mobile coverage and emergencies
NSW National Parks warns that alpine areas often have little or no mobile reception, and you may not be able to call for help. Even if your phone shows a signal at the top of the chairlift, do not plan around it. Personal Locator Beacons can be borrowed free of charge at park visitor centres, and the service recommends leaving a trip intention form with family or friends. The emergency number in Australia is 000; dialling 112 on a mobile is redirected to it, and emergency calls can go through another carrier's network if your own has no coverage. The Emergency+ app shows your GPS position to read out to the operator.
Dangers and safety
The altitude is too low to cause altitude sickness. The main risks are cold, wind and poor visibility: hypothermia can set in on a wet, windy summer day, and in winter the Main Range sees whiteouts and avalanches in steep gullies and below cornices. Sunburn is a real issue at this height in summer. The deaths of two skiers in 1928 led to the building of Seaman's Hut, which still holds firewood and emergency food. Call for help early: rescues become much harder after dark.
History and name
The Ngarigo people and their neighbours came to the high country in summer to feast on bogong moths. In 1840 Strzelecki, with James Macarthur and two Aboriginal guides, Charley Tarra and Jackey, came up from the Geehi valley via Hannel's Spur. On reaching what is now Mount Townsend he saw that the neighbouring peak was slightly higher and reached it on 12 March 1840. He named it after Tadeusz Kościuszko, leader of the 1794 Polish uprising and a veteran of the American Revolutionary War, saying it reminded him of the Kościuszko Mound in Kraków.
A mistake on Victorian maps then swapped the positions of Mount Kosciusko and Mount Townsend. In 1885 the Austrian explorer Robert von Lendenfeld, using such a map, climbed Mount Townsend believing it to be Kosciusko. The confusion was finally cleared up in 1940 by B. T. Dowd, a cartographer and historian of the NSW Lands Department, who showed that Strzelecki had named the right summit.
In 1897 the meteorologist Clement Wragge set up a weather observatory on the summit. The Kosciusko Chalet at Charlotte Pass opened in 1930. The area was first protected in 1906 as the National Chase Snowy Mountains and became Kosciuszko National Park in 1967; at about 6,900 km² it is the largest national park in New South Wales and part of the Australian Alps National Parks, added to the National Heritage List in 2008. The anglicised spelling Kosciusko was officially changed to Kosciuszko in 1997. In 2019 the dual name Kunama Namadgi was proposed, but its meaning was disputed by Aboriginal representatives and it has not been adopted.
Interesting facts
- The traditional Australian pronunciation is "KOZ-ee-USK-oh"; a version closer to the Polish, "ko-SHOOSH-ko", is increasingly heard.
- The Rawson Pass toilet, built in 2007 for the summer crowds, is the highest public toilet in Australia.
- The Main Range carries clear marks of the last ice age about 20,000 years ago: cirques, moraines and tarns such as Blue Lake and Lake Cootapatamba.
- The park shelters the endangered mountain pygmy possum and the corroboree frog, one of Australia's most threatened animals; feral horses, estimated at about 17,000 in 2023, are a major management problem.
- Kosciuszko was not formed by volcanic activity but by slow uplift of an ancient landscape, which is why the top is a rounded dome.
- The Snowy Mountains Scheme, completed in 1974 and still the largest engineering project ever undertaken in Australia, diverts water from the rivers that drain the range.
