Australia's main mountain range is the Great Dividing Range on the east coast. The eastern seaboard is where most Australians live, as this area gets substantial rainfall to support a large population. Most of Australia is actually desert or semi arid. The south of both Western and South Australia supports reasonably large populations. Both areas enjoy a mediterranean climate. The island state of Tasmania, just below the Australian continent is one of the most mountainous islands on Earth and has a temperate climate with regular rainfall
The highest peak in Australia is not Mt Kosciuszko on the main continent as most think, rather it is Mawson's Peak on Heard Island which is located in the Southern Ocean, south of the Australia continent and near the Antarctica. This mountain is an active volcano which stands 2745 metres high. There are higher mountains in the Australian Antarctic Territory, but this territory is not sovereign to Australia
The highest mountains on the mainland are in the Snowy Mountains in New South Wales, which are part of the Great Dividing Range. This range is the third longest in the world and it separates the central lowlands from the eastern highlands and spans Victoria in the south, through all of New South Wales, and ends in Northen Queensland's Cape York Peninsula. These are the mountains to the right of the map
The small long and narrow Mountain range in South Australia is called the Flinders Ranges which are visible at the bottom middle of the map
The north of Western Australia contains some isolated ranges such as the King Leopold and Hamersley ranges
Central Australia is a flat plain with some eroded mountain ranges, including the Macdonnell Ranges in the southern part of the Northern Territory down to the Musgrave Ranges and Stuart Range in the northern part of South Australia
The Island state of Tasmania contains rugged mountains and is geologically part of the Great Dividing Range in the mainland
