The
Territory of Papua comprised the southeastern quarter of the island of
New Guinea from 1883 to 1975. In 1883, the Government of
Queensland annexed this territory for the British Empire. The United Kingdom Government refused to ratify the annexation but in 1884 a
Protectorate was proclaimed over the territory, then called "British New Guinea". There is a certain ambiguity about the exact date on which the entire territory was annexed by the British. The
Papua Act 1905 recites that this happened "on or about" 4 September 1888. On 18 March 1902, the Territory was placed under the authority of the Commonwealth of Australia. Resolutions of acceptance were passed by the Commonwealth Parliament, who accepted the territory under the name of Papua.
