What does Mabo Day mean?

Mabo Day commemorates the High Court of Australia’s Mabo v Queensland (No 2) decision of 3 June 1992. The decision recognised that Aboriginal and Torres Strait Islander peoples’ rights to land could continue under traditional laws and customs and be recognised by Australian common law.

Eddie Koiki Mabo

Eddie Koiki Mabo was a Torres Strait Islander man from Mer, also known as Murray Island, whose legal challenge helped transform native title law in Australia.

Native title

The Mabo decision recognised native title and helped lead to the Native Title Act 1993.

Terra nullius

The decision rejected the legal fiction of terra nullius, the idea that the land belonged to no one before British settlement.

Respectful note: Mabo Day should not be reduced to a generic legal anniversary. It is deeply connected to Torres Strait Islander history, land, identity, family, resistance and justice.

Who was Eddie Koiki Mabo?

Eddie Koiki Mabo was a Torres Strait Islander man from Mer in the Torres Strait. His name is closely linked to one of the most significant legal decisions in Australian history. Although he died before the decision was handed down, his advocacy and legal case helped change the way Australian law recognised Indigenous relationships to land.

Mer / Murray Island

Eddie Mabo’s connection to Mer and Meriam law and custom was central to the legal challenge.

Land rights

The Mabo case challenged the idea that Indigenous land interests had no recognition in Australian common law.

Legacy

Mabo Day honours Eddie Mabo’s role and the broader struggle of Aboriginal and Torres Strait Islander peoples for land rights and recognition.

Mabo Day and National Reconciliation Week

Mabo Day falls on 3 June, which is also the final day of National Reconciliation Week. This makes Mabo Day a key date in Australia’s reconciliation calendar.
