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.

On 13 May 1787 a fleet of 11 ships, which came to be known as the First Fleet, was sent by the British Admiralty from England to New Holland. Under the command of Captain Arthur Phillip, the fleet sought to establish a penal colony at Botany Bay on the coast of New South Wales, which had been explored and claimed by Lieutenant James Cook in 1770. The settlement was seen as necessary because of the loss of the Thirteen Colonies in North America. The Fleet arrived between 18 and 20 January 1788, but it was immediately apparent that Botany Bay was unsuitable.
