The Pedirka Desert is a small Australian desert, about 100 km north-west of Oodnadatta and 250 km north-east of Coober Pedy in South Australia. Mount Dare and Witjira National Park are just to the north. The desert is relatively small, occupying about 1250 km2. Pedirka Desert belongs to the Finke bioregion. The sands are deep-red and it is vegetated by dense mulga woodlands. Dunes in the desert are low, eroded, widely spaced and positioned parallel to each other. Although the land is not over-appealing to pastoralists, it is progressively being developed.
