The Australian Alps is a mountain range in southeast Australia. It comprises an interim Australian bioregion, and is the highest mountain range in Australia. The range straddles the borders of eastern Victoria, southeastern New South Wales, and the Australian Capital Territory. It contains Australia's only peaks exceeding 2,000 m in elevation, and is the only bioregion on the Australian mainland in which deep snow falls annually. The range comprises an area of 1,232,981 ha.
The Australian Alps is part of the Great Dividing Range, the series of mountain and hill ranges and tablelands that runs about 3,000 km from northern Queensland, through New South Wales, and into the northern part of Victoria. This chain of highlands divides the drainage of the rivers that flow to the east into the Pacific Ocean from those that flow west into the drainage of the Murray–Darling Basin or into inland waters, such as Lake Eyre, which lie below sea level, or else evaporate rapidly.
