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.
Australian Squadron
As a British force, the Australia Squadron ceased on 4 October 1913, when the ships of the Royal Australian Navy (RAN) entered Sydney Harbour for the first time. However, the term was subsequently used between 1926 and 1949 to refer to the ships of the RAN: after the decommissioning and scuttling of the battlecruiser and other cutbacks, the term 'Australian Fleet' was thought to be inappropriate to describe the navy's strength. HMAS Melbourne served as squadron flagship between 1922 and 1928.
