Australia–United Kingdom relations
In 1766 during his first voyage to the Pacific, Royal Navy captain James Cook sailed along and mapped the east coast of Australia, which he named New South Wales and claimed for Great Britain. Seventeen years later, following the loss of its American colonies in 1783, the British Government sent a fleet of ships, the "First Fleet", under the command of Captain Arthur Phillip, to establish a new penal colony in New South Wales. A camp was set up and the flag raised at Sydney Cove on 26 January 1788, and the British Crown Colony of New South Wales was formally promulgated on 7 February 1788. Further Crown Colonies were established in Van Diemen's Land (now known as Tasmania) in 1803; Swan River Colony (now known as Western Australia) in 1828; South Australia in 1836; Victoria in 1851; and Queensland in 1859. The six colonies federated in 1901 and the Commonwealth of Australia was formed as a Dominion of the British Empire.
History of Australia (1901–45)
The First Fleet of British ships had arrived at Sydney Harbour in 1788, founding the first of what would evolve into six self-governed British colonies: New South Wales, Tasmania, South Australia, Western Australia, Victoria and Queensland. The last British garrisons had left Australia in 1870. At the beginning of the 20th century, nearly two decades of negotiations on Federation concluded with the approval of a federal constitution by all six Australian colonies and its subsequent ratification by the British parliament in 1900. This resulted in the political integration of the six Australian colonies into one federated Australian Commonwealth, formally proclaimed on 1 January 1901.
