Which desert lies in both Western Australia and South Australia? The answer is the Great Victoria Desert.

The Great Victoria Desert is Australia's largest desert and stretches across a broad belt of inland Western Australia and South Australia. It contains sand ridges, spinifex grasslands, shrubland, gravelly desert pavement, and salt lakes rather than one continuous sea of dunes.

British explorer Ernest Giles became the first recorded European to cross it in 1875 and named it for Queen Victoria, who was then the reigning British monarch. The region remains sparsely populated, but it is part of the traditional country of Aboriginal peoples including the Pitjantjatjara, Mirning, and Kogara.

The Great Victoria is often confused with Australia's Great Sandy, Gibson, or Simpson deserts. Those are separate desert regions. The Great Victoria is distinctive because it crosses the Western Australia–South Australia border and extends for more than 700 kilometres from west to east.
