 The new bill finally passed through both Houses in March 1981, as the "Pitjantjatjara Land Rights Act 1981" (SA), later renamed as the "Anangu Pitjantjatjara Yankunytjatjarra Land Rights Act 1981" (SA) (APYLRA).Symbolically, the Act came into force on 2 October 1981, the one-year anniversary of the date when Premier David Tonkin and the Chairman of the Pitjantjatjara Council, Mr Kawaki Thompson, signed their agreement to the Pitjantjatjara Land Rights Bill.The new law was enacted to acknowledge Anangu ownership of the land; to establish the Anangu Pitjantjatjara Yankunytjatjara Land Management (APY) as a body corporate; and to "provide for efficient and accountable administration and management of lands by Anangu Pitjantjatjara Yankunytjatjarra".
