Desert Location:

The Great Victoria Desert is the biggest desert in Australia and consists of many small sandhills, grassland plains, areas with a closely packed surface of pebbles (called desert pavement or gibber plains) and salt lakes. 

The Great Victoria Desert is over 700 kilometres (430 mi) wide (from west to east) and covers an area of 424,400 square kilometres (163,900 sq mi) from the Eastern Goldfields region of Western Australia to the Gawler Ranges in South Australia.

The Western Australia Mallee shrub ecoregion lies to the west, the Little Sandy Desert to the northwest, the Gibson Desert and the Central Ranges xeric shrublands to the north, the Tirari and Sturt Stony deserts to the east, while the Nullarbor Plain to the south separates it from the Southern Ocean.

Type of Desert: Hot

Summer daytime temperatures range from 32 to 40 °C (90 to 104 °F) while in winter, this falls to 18 to 23 °C (64 to 73 °F).

Desert Precipitation:

Average annual rainfall is low and irregular, ranging from 200 to 250 mm (7.9 to 9.8 in) per year. Thunderstorms are relatively common in the Great Victoria Desert, with an average of 15–20 thunderstorms per annum.

Desert Flora and Fauna:

The Great Victoria desert is a World Wildlife Fund ecoregion  and an Interim Biogeographic Regionalisation for Australia (IBRA) region.As this area has never been used for agriculture, habitats remain largely undisturbed while parts of the desert are protected areas including Mamungari Conservation Park (formerly known as Unnamed Conservation Park) in South Australia, a large area of pristine arid zone wilderness which possesses cultural significance and is one of the fourteen World Biosphere Reserves in Australia.

Habitat is also preserved in the large Aboriginal local government area of Anangu Pitjantjatjara Yankunytjatjara in South Australia and in the Great Victoria Desert Nature Reserve of Western Australia.

The nuclear weapons trials carried out by the United Kingdom at Maralinga and Emu Field in the 1950s and early 1960s have left areas contaminated with plutonium-239 and other radioactive material.

Only the hardiest of plants can survive in much of this environment. Between the sand ridges there are areas of wooded steppe consisting of Eucalyptus gongylocarpa, Eucalyptus youngiana and mulga (Acacia aneura) shrubs scattered over areas of resilient spinifex grasses particularly Triodia basedowii.

Wildlife adapted to these harsh conditions includes few large birds and mammals, but the desert does sustain many types of lizards, including the great desert skink (Egernia kintorei).  A number of small marsupials include the Sandhill Dunnart (Sminthopsis psammophila) and the Crest-tailed Mulgara (Dasycercus cristicauda).

One way to survive here is to burrow into the sands, as a number of the desert's animals, including the endangered Southern Marsupial Mole (notoryctes typhlops), and the Water-holding Frog do.

Birds include the Chestnut-breasted Whiteface (Aphelocephala pectoralis) found on the eastern edge of the desert and the malleefowl of Mamungari Conservation Park.

Predators of the desert include the dingo (as the desert is north of the Dingo Fence) and two large monitor lizards, the perentie (Varanus giganteus) and the sand goanna (Varanus gouldii).
