Mabo v Queensland (No 2) (commonly known as the Mabo case or simply Mabo; /mɑːboʊ/ MAH-bo) is a landmark decision of the High Court of Australia that recognised the existence of Native Title in Australia. It was brought by Eddie Mabo and others against the State of Queensland, and decided on 3 June 1992. The case is notable for being the first in Australia to recognise pre-colonial land interests of Indigenous Australians within the common law of Australia.
Mabo is of great legal, historical, and political importance to Aboriginal and Torres Strait Islander Australians. The decision rejected the notion that Australia was terra nullius (i.e. owned by no one) at the time of British settlement, and recognised that Indigenous rights to land existed by virtue of traditional customs and laws and these rights had not been wholly lost upon colonisation.
