Jean-François de Galaup, comte de Lapérouse
The expedition continued to Australia, arriving off Botany Bay on 24 January 1788. There Lapérouse encountered a British convoy (known later as the "First Fleet") led by Captain Arthur Phillip RN, who was to establish the penal colony of New South Wales. While it had been intended that the colony would be located at Botany Bay, Phillip had quickly decided that the site was unsuitable and the colony would instead be established at Sydney Cove in Port Jackson. High winds – which had hindered Lapérouse's ships in entering Botany Bay – delayed the relocation until 26 January (later commemorated as Australia Day).
Convicts in Australia
On 18 August 1786 the decision was made to send a colonisation party of convicts, military, and civilian personnel to Botany Bay under the command of Admiral Arthur Phillip who was to be the Governor of the new colony. There were 775 convicts on board six transport ships. They were accompanied by officials, members of the crew, marines, the families thereof and their own children who together totaled 645. In all, eleven ships were sent in what became known as the First Fleet. Other than the convict transports, there were two naval escorts and three storeships. The fleet assembled in Portsmouth and set sail on 13 May 1787.
