Eddie Koiki Mabo was a Torres Strait Islander activist and land rights campaigner whose landmark High Court case, Mabo v Queensland (No 2), delivered on 3 June 1992, overturned the legal fiction of terra nullius — the colonial doctrine that Australia was land belonging to no one — and established Native Title as part of Australian law for the first time. Mabo died of cancer on 21 January 1992, five months before the verdict he had fought for since 1982 was handed down.
Who Was Eddie Mabo and What Was His Background?
Born on 29 June 1936 on Mer (Murray Island) in the Torres Strait, Eddie Koiki Mabo grew up with a deep connection to his ancestral land. Adopted by his uncle Benny Mabo after his mother died in childbirth, he was raised within the traditions of the Meriam people. He worked as a gardener, railway worker, and canecutter before settling in Townsville, Queensland, where he became a prominent community organiser and co-founded the Townsville Black Community School in 1973. A pivotal moment came at a 1974 conference when Mabo discovered that Queensland law regarded his family's land on Mer as belonging to the Crown, not to the Meriam people who had lived there for generations.
How Did the Mabo Legal Case Unfold Between 1982 and 1992?
In 1982, Mabo and four other Meriam Islanders — Sam Passi, David Passi, Celuia Mapo Salee, and James Rice — launched proceedings in the High Court of Australia, arguing that the Meriam people held traditional ownership of Mer. The Queensland government attempted to extinguish the claim by passing the Queensland Coast Islands Declaratory Act 1985, which was itself struck down by the High Court in 1988 in Mabo v Queensland No 1 as inconsistent with the Racial Discrimination Act 1975. The case then proceeded on its merits, with Justice Moynagh conducting hearings on Mer itself in 1989. After a decade of litigation, the High Court ruled 6 to 1 in favour of Mabo on 3 June 1992, finding that the Meriam people had continuously occupied and used Mer and therefore held Native Title to the island.

What Was the Legacy of the Mabo Decision for Australia?
The Mabo decision fundamentally reshaped the legal and moral landscape of Australia. It forced the nation to confront its colonial past and acknowledge that Aboriginal and Torres Strait Islander peoples had a continuous and sovereign connection to their land long before British settlement in 1788. The Keating government responded by passing the Native Title Act 1993, creating a framework for Indigenous Australians to claim legal recognition of their traditional land rights. By 2023, over 3.3 million square kilometres — roughly 43 percent of Australia's land mass — had been recognised under Native Title determinations. Mabo himself was posthumously awarded the Human Rights Medal in 1992, and 3 June is now observed as Mabo Day across Australia.
