North Australia was (1) the name of a briefly proclaimed but never established British colony and (2) a former part of theNorthern Territory of Australia administered as "North Australia".

Acolony of North Australia was briefly authorised by the British government byletters patent of 17 February 1846 but never established. The colony was to comprise that part of theColony of New South Wales that is now theNorthern Territory of Australia and that is now that part of the state ofQueensland lying north of the26th parallel. The colony was intended as a newpenal colony after the end oftransportation to the existing Australian colonies.[1] Since 1822, whenJohn Bigge recommended the establishment of a convict settlement atPort Curtis (now the location ofGladstone, Queensland), the idea had been revived several times. As some difficulty was being experienced in finding work for time-expired convicts inVan Diemen's Land (Tasmania), it was decided to try the experiment of sending them to a new area and giving them land and a certain amount of government help.Edward Smith-Stanley, 14th Earl of Derby andWilliam Ewart Gladstone, successive secretaries of state for the colonies, fathered the project.[2]Charles Augustus FitzRoy, theGovernor of New South Wales, was to be the Governor and, in May 1846,ColonelGeorge Barney was appointed to beLieutenant-Governor and Superintendent. Gladstone selected Barney as a man used to authority and with previous experience in Australia. Barney was dispatched and arrived in Sydney on 15 September 1846 on theWilliam Hyde. He quickly surveyed the coast in a small steamer, decided that Port Curtis was the most suitable place for a settlement and returned to Sydney. However, after a change of government ministries in Britain,Henry Grey, 3rd Earl Grey succeeded Gladstone, and he promptly vetoed the whole project and the letters patent authorising the colony were revoked in December 1846.[2]
Report of the revocation did not reach Australia and Barney until 15 April 1847. On 8 January 1847, Barney, his family, various officials and 87 soldiers and convicts sailed on the chartered barqueLord Auckland. The ship arrived off the southern entrance of Port Curtis and ran aground on shoals off the southern tip ofFacing Island. On 30 January 1847, the (already revoked) colony of North Australia was proclaimed at Settlement Point on Facing Island and Barney was sworn in as Lieutenant Governor. The settlers spent seven weeks on Facing Island before being rescued by the supply shipThomas Lowry and delivered to the intended site of settlement, the region now known asBarney Point.[3] There was much discomfort from the extreme summer heat. News of the revocation of the colony reached Barney and the party returned to Sydney.[2] The convict settlement lasted barely two months and cost the British government £15,000.[4]
The colony's intended role as a convict penal settlement attracted much criticism in theNew South Wales Legislative Council.[5][6]

North Australia was a short-lived administrative area of theNorthern Territory of Australia.George Pearce,Minister for Home and Territories in the federal government in the 1920s, thought[citation needed] that theNorthern Territory of Australia was too large, sparsely populated and disparate to be adequately administered as a whole. So, on 1 February 1927, under theNorthern Australia Act 1926 (Cth), administration the Northern Territory was split into two administrative areas,North Australia andCentral Australia, respectively above and below latitude 20° S.[7][8][9][10] However, on 12 June 1931, administration of the Northern Territory reverted to a single area and administration.
