The Great Victoria Desert is considered the largest desert in Australia, spanning an area of approximately 647,000 square kilometers (250,000 square miles). It is located in the southern part of the country, straddling the border between Western Australia and South Australia.

This desert is characterized by its expansive sandy plains, dunes, and shrubland, making it an important ecological area that supports a unique array of flora and fauna. The name "Great Victoria Desert" has historical significance, named after Queen Victoria, and it holds a prominent place in Australia's geographic landscape.

The other deserts listed, while significant in their own right, do not surpass the Great Victoria Desert in area. The Simpson Desert, for example, is known for its iconic red dunes but is smaller in size. The Great Sandy Desert is also expansive but ranks below the Great Victoria Desert. Finally, the Nullarbor Desert, primarily a flat, arid region, is not as extensive in area when compared to the Great Victoria Desert.
