There are many more than three deserts in Australia, but the main ones and their location are: Great Victoria Desert (Western Australia): 424,400 km2 (163,900 square miles). Great Sandy Desert (Western Australia): 284,993 km2 (110,036 square miles).
By far the largest part of Australia is the desert or semi-arid lands commonly known as the outback. Most of the population lives along the temperate eastern and southeastern coastline, in cities like Brisbane, Sydney, Canberra and Melbourne. Though very modern Australia is nevertheless a place for the nature lover.
