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.
European maritime exploration of Australia
In 1768 British Lieutenant James Cook was sent from England on an expedition to the Pacific Ocean to observe the transit of Venus from Tahiti, sailing westwards in via Cape Horn and arriving there in 1769. On the return voyage he continued his explorations of the South Pacific, in search of the postulated continent of Terra Australis. He first reached New Zealand, and then sailed further westwards to sight the south-eastern corner of the Australian continent on 20 April 1770. In doing so, he was to be the first documented European expedition to reach the eastern coastline. He continued sailing northwards along the east coast, charting and naming many features along the way. He identified Botany Bay as a good harbour and one potentially suitable for a settlement, and where he made his first landfall on 29 April. Continuing up the coastline, the "Endeavour" was to later run aground on shoals of the Great Barrier Reef (near the present-day site of Cooktown), where she had to be laid up for repairs. The voyage then recommenced, eventually reaching the Torres Strait and thence on to Batavia.
