Pitjantjatjara were forced to move here by the Australian government in the 1950s. Large parts of their land in the north were made into the Woomera Test Range, a weapons testing area. The families were first moved south, to a Christian mission at Ooldea. They were moved to Yalata, even further south, in 1952. This second move was done because of nuclear-weapon tests being done at Maralinga and Emu Field. The title to the lands around Maralinga (Maralinga Tjarutja) was given back to the Aboriginal people by the South Australian Parliament in December 1984. People from Yalata and further inland resettled on the land in 1995.
