Some States and Territories of Australia retained discriminatory laws relating to voting rights for Aborigines into the 1960s, at which point full legal equality was established. A 1967 referendum to include all Aborigines in the national electoral roll census was overwhelmingly approved by voters. In 1984, a group of Pintupi people who were living a traditional hunter-gatherer desert-dwelling life were tracked down in the Gibson Desert and brought into a settlement. They are believed to have been the last uncontacted tribe.
