AIATSIS - Eddie Koiki MaboEddie Koiki Mabo's campaign for Indigenous land rights led to a landmark decision of the High Court of Australia, on 3 June 1992 that overturned the legal fiction of terra nullius. Recognising the High Court's ruling in Mabo remains the basic legal document on native title. Native title is the recognition that Aboriginal and Torres Strait Islander people have rights and interests to land and waters according to their traditional law and customs as set out in Australian Law, governed by the Native Title Act 1993 (Cth).
