European exploration of Australia
With 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, Port Jackson, on 26 January 1788, a date which became Australia's national day, Australia Day. A British settlement was established in Van Diemen's Land, now known as Tasmania, in 1803, and it became a separate colony in 1825. The United Kingdom formally claimed the western part of Western Australia (the Swan River Colony) in 1828. Separate colonies were carved from parts of New South Wales: South Australia in 1836, Victoria in 1851, and Queensland in 1859. The Northern Territory was founded in 1911 when it was excised from South Australia. South Australia was founded as a "free province"—it was never a penal colony. Victoria and Western Australia were also founded "free", but later accepted transported convicts. A campaign by the settlers of New South Wales led to the end of convict transportation to that colony; the last convict ship arrived in 1848.
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.
