wasteland, southern Australia. It lies in Western and South Australia, between the Gibson Desert on the north and the Nullarbor Plain on the south and extends eastward 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, partly fixed by Triodia (Spinifex) grass and salt marshes, it was penetrated (from east to west) in 1875 by a party led by the explorer Ernest Giles, who named it Great Victoria Desert. Crossed by the Laverton–Warburton Mission Track (which links the mission station in the Warburton Range, in Western Australia, with Laverton, 350 miles 【560 km】 southwest), it is also tracked for the recovery of missiles whose trajectories are guided from the weapons-testing range that is located at Woomera. There are several national parks and reserves in the area, including the Great Victoria Desert Nature Reserve, Nullarbor National Park, and the Flora and Fauna Conservation Park.
