Colony of New South Wales
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, until 1792. 18 January 1788, the first ship of the First Fleet, with Phillip aboard, reached Botany Bay. Botany Bay found unsuitable by Phillip. After Phillip led exploration of Port Jackson, he, on the first ship, sailed and reached Sydney Cove on night of 25 January 1788. On morning of 26 January, men on board this ship went ashore and started clearing land for a camp. 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, especially that having what today we call vitamin C. The female convicts came ashore on 6 February 1788 and likely officers wives and children if any. About mid-day 7 February 1788, 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. Colony of NSW founded 7 February 1788. Before that, British naval administration applied.
Australia–New Zealand relations
The first European landing on the Australian continent occurred in the Janszoon voyage of 1605–06. Abel Tasman in two distinct voyages in the period 1642–1644 is recorded as the first person to have coastally explored regions of the respective landforms including Van Diemen's Land – later named for him as the Australian state of Tasmania. The first voyage of James Cook stands as significant for the circumnavigation of New Zealand in 1769 and as the European discovery and first ever coastal navigation of Eastern Australia from April to August 1770. The European settlement of Australia and New Zealand, then referred to as the colony of New South Wales, dates from the arrival of the First Fleet into Cadi/Port Jackson on Australia Day, 1788.
