The Australian Alps are a mountain range in southeast Australia. The range comprises an interim Australian bioregion, and is the highest mountain range on mainland Australia. The range straddles the borders of eastern Victoria, southeastern New South Wales, and the Australian Capital Territory. It contains the only peaks exceeding 2,000Â m (6,600Â ft) in elevation on the Australian mainland, and is the only bioregion on the Australian mainland in which deep snow falls annually. The range comprises an area of 1,232,981Â ha (3,046,760 acres).
The Australian Alps are part of the Great Dividing Range, the series of mountain and hill ranges and tablelands that runs about 3,000 km (1,900 mi) 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 (and thence to the Southern Ocean) or into inland waters, such as Lake Eyre, which lie below sea level, or else evaporate rapidly.
