Tonkin signed the Pitjantjatjara Land Rights Act on 2 October 1981, putting the bill into effect. The freehold title to the land was given to the Pitjantjatjara, Yankunytjatjara and Ngaanyatjarra peoples, who formed a council as the local government. The grant included the former leasehold areas in the eastern portion: Everard Park, Kenmore Park and Granite Downs. A portion of the southeast of the APY lands (about ) still overlaps with the Woomera Test Range.
