The Colony of New South Wales was a colony of the British Empire from 1788 to 1901, when it became a State of the Commonwealth of Australia. At its greatest extent, the colony of New South Wales included the present-day Australian states of New South Wales, Queensland, Victoria, Tasmania, and South Australia, the Northern Territory as well as New Zealand. The first "responsible" self-government of New South Wales was formed on 6 June 1856 with Sir Stuart Alexander Donaldson appointed by Governor Sir William Denison as its first Colonial Secretary. History Formation On 18 January 1788, the First Fleet led by Captain Arthur Phillip founded the first British settlement in Australian history as a penal colony. Having set sail on 13 May 1787, Captain Arthur Phillip assumed the role of governor of the settlement upon arrival.

In the afternoon-evening, they erected a flag pole, raised the Union Jack, and the officers ashore made toasts to the Royal Family and the success of the colony. Likely, some, or all, ships of the First Fleet were present for the flag raising. On the morning of 27 January, all the fit male convicts, marines, and likely some ships' crew went ashore to establish the camp and find food. The female convicts came ashore on 6 February 1788. About midday on 7 February, the convicts, marines and others who were staying were gathered by the Governor for the reading of the proclamation of New South Wales and a long reading of the rights of the convicts and others. Thus, the Colony of New South Wales was formally proclaimed on 7 February 1788. Before that, British naval administration applied.
