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.
Australian Air Corps
On 17 June 1920, Cole, accompanied by De La Rue, flew a DH.9A to an altitude of , setting an Australian record that stood for more than ten years. The effects of hypoxia exhibited by Cole and De La Rue intrigued the medical officer, Captain Arthur Lawrence, who subsequently made observations during his own high-altitude flight piloted by Anderson; this activity has been credited as marking the start of aviation medicine in Australia. Later that month, flying an Avro 504L floatplane, De La Rue became the first person to land an aircraft on the Yarra River in Victoria. On 22 July, Williams, accompanied by Warrant Officer Les Carter, used a DH.9A to make the first non-stop flight from Sydney to Melbourne. A few days earlier, Williams and Wackett had flown two DH.9As to the Royal Military College, Duntroon, to investigate the possibility of taking some of the school's graduates into the air corps, a plan that came to fruition after the formation of the RAAF.
Between July and November 1920, trials of the Avro 504L took place on the Navy's flagship, HMAS "Australia", and later aboard the light cruiser HMAS "Melbourne". The trials on "Melbourne", which operated in the waters off New Guinea and northern Australia, demonstrated that the Avro was not suited to tropical conditions as its engine lacked the necessary power and its skin deteriorated rapidly; Williams recommended that activity cease until Australia acquired a purpose-designed seaplane.
