Great Sandy Desert (Western Australia): 284,993 km2 (110,036 square miles). Tanami Desert (Western Australia and Northern Territory): 184,500 km2 (71,235 square miles). Each of these deserts is either in or primarily in Western Australia, in the western third of the continent.

Most of the population lives along the temperate eastern and southeastern coastline, in cities like Brisbane, Sydney, Canberra and Melbourne.
