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.
Cronulla sand dunes
The Kurnell Peninsula, also the site of the Cronulla Sand Dune System was the first landing place for Captain James Cook in Australia. On 29 April 1770, HM Bark "Endeavour" landed in Botany Bay and Cook stepped ashore. Shortly after, James Cook looked down from the sand hills at what is now known as Cronulla Beach. The sand dunes were completely covered in vegetation, so Cook made no mention of any sand dunes during his visit to the Kurnell peninsula. Cook along with his crew stayed in Botany Bay for eight days. During his visit he collected botanical specimens, mapped the area and tried to make contact (unsuccessfully) with the indigenous population. When Cook reported back to England he said that the land was suitable for agriculture, it had sandy soil and the area was lightly wooded. Captain Arthur Phillip, arriving with the First Fleet, stepped ashore on 18 January 1788, after following Cook's advice. They began to clear land and dig wells, but a week later decided to abandon the site and sail north to Port Jackson.
