Answer

Who colonized Australia?

Oceania — the powers that ruled Australia, the dates, and what independence did and did not change.

In short

Who colonized Australia?

Britain. The British claimed the continent in 1770 and began penal settlement in 1788 under the legal fiction of terra nullius, which the High Court overturned only in 1992.

Australia was colonised on a legal claim that nobody lived there. Terra nullius made dispossession a matter of paperwork rather than conquest, and it stood as law until 1992.

How rule changed in Australia

These periods describe different governing arrangements. The presence of a trading company, a military occupation and direct colonial government are not interchangeable; the notes preserve those distinctions where the record identifies them.

Periods may overlap where control differed by territory. A national independence date does not imply that every enclave or dependency changed status on that day.

Questions

Frequently asked

Who colonised Australia?
Britain, from the 1788 penal settlement at Sydney Cove.
What was terra nullius?
The legal doctrine that Australia belonged to no one before the British arrived, which allowed the Crown to claim sovereignty without treaty or purchase. It was overturned by the Mabo judgment in 1992.
Is Australia still a British colony?
No. It federated in 1901 and holds full legal autonomy, though the British monarch remains head of state.
