Major Australian Deserts
The five largest deserts in Australia include the Great Victoria Desert: 424,400 km2, Great Sandy Desert: 284,993 km2, Tanami Desert: 184,500 km2, Simpson Desert: 176,500 km2, and the Gibson Desert: 156,000 km2.
The map above shows the general location of the five major deserts. A recent trend has been an increase in rainfall in these arid areas. For example some parts of the Gibson desert have doubled in rainfall from an average of 150 mm to 300 mm annually.
Along with this increase in rainfall in the desert regions, there has been a decrease in southern areas. Scientists say that this is the result of north-west cloud bands that used to bring rain to southern regions, moving north over central Australia.
