Great Victoria Desert
Great Victoria Desert, large area of shifting sand dunes in southwestern Australia, south of Gibson Desert and north of the Nullarbor Plain. The desert, 250,000 sq mi (647,000 sq km) in area, was named by explorer Ernest Giles in 1875. An aboriginal reserve occupies much of the desert's eastern end. The area is tracked for the recovery of missiles from the weapons-testing range at Womera.
