Australia as terra nullius with no Indigenous land rights

Australian common law treated the continent as if Indigenous peoples possessed no land rights recognizable by the common law at British acquisition of sovereignty, allowing the Crown's title to be treated as complete ownership rather than as a radical title burdened by surviving native title.

Current understanding

In Mabo v Queensland (No 2) in 1992, the High Court of Australia rejected the legal assumptions associated with terra nullius. The Court held that Aboriginal and Torres Strait Islander peoples had their own laws and customs and that native title could survive the Crown's acquisition of sovereignty. The Crown acquired radical title, not automatic full beneficial ownership of every parcel of land. Native title could nevertheless be extinguished by valid governmental acts inconsistent with its continued existence.

Consequences and human impact

The doctrine was embedded in Australian land law rather than remaining an abstract historical claim. In Cooper v Stuart in 1889, the Privy Council described New South Wales as practically unoccupied and without settled inhabitants or settled law when annexed. Australian courts later treated Indigenous customary land rights as legally unrecognised, including in the 1971 Gove land-rights case. Mabo reversed that foundation in 1992, and Parliament enacted the Native Title Act in 1993 to provide a statutory framework for recognition and protection of surviving native title.

How the consequences followed

The phrase terra nullius is commonly used to describe the doctrine, but the card does not claim that British officials in 1788 formally proclaimed Australia under that Latin label. The legal assumption developed through colonial practice and later judicial doctrine.

Mabo did not invalidate British sovereignty over Australia. It distinguished sovereignty from ownership: the Crown's acquisition of sovereignty gave it radical title and power to extinguish rights, but did not automatically erase all pre-existing Indigenous proprietary rights.

The card does not attribute every act of Indigenous dispossession solely to terra nullius. Violence, legislation, pastoral expansion, reserves, removals and many other institutions also drove dispossession. The doctrine mattered because it denied a common-law starting point for Indigenous ownership.

Institutional episode

Australia

1889–1992Policy basis

The institutional belief was not simply that Europeans had arrived first or that Indigenous people were absent. Australian law treated Indigenous systems of landholding as incapable of generating property rights recognised by the common law. Mabo rejected that legal fiction and held that native title could survive sovereignty, changing the foundation of Australian land law while leaving room for earlier valid acts to have extinguished title.

Institutional machinery

Colonial governments had already treated vast areas as Crown land, but Cooper v Stuart in 1889 supplied a particularly clear judicial statement that New South Wales had been practically unoccupied and without settled law when annexed. The resulting legal framework treated Indigenous customary interests as outside ordinary common-law property recognition. In Milirrpum v Nabalco in 1971, the Northern Territory Supreme Court rejected a claim to native title. The High Court's Mabo (No 2) judgment on 3 June 1992 reversed that foundation by recognising that native title survived the acquisition of sovereignty where it had not been validly extinguished.
