Arid region, Western Australia and South Australia .
Lying between Gibson Desert on the north and Nullarbor Plain on the south, it extends east from Kalgoorlie almost to the Stuart Range. Much of its eastern end is occupied by the Central and North West Aboriginal reserves. A vast expanse of sand hills, it is crossed by the LavertonWarburton Mission Track, which links the mission station in the Warburton Range with Laverton, 350 mi (560 km) southwest. There are several national parks and reserves in the area, including the Great Victoria Desert Nature Reserve and the Nullarbor National Park.
