Deserts of Australia cover 1,371,000 square kilometres (529,000 sq mi), or 18% of the Australian mainland. However, approximately 35% of the Australian continent receives so little rain it is effectively desert. The deserts in Australia are primarily distributed throughout the western plateau and interior lowlands of the continent.[1]
By international standards Australian deserts receive relative high rates of rainfall.[2] No weather station situated in an arid region records less than 100 mm of average annual rainfall.[3] The deserts of Australia, particularly in the interior, lack any significant summer rains.[2]
Deserts are not necessarily completely devoid of vegetation, but have large areas where vegetation is very limited in height or extent.
