The First Fleet was commanded by Commodore Arthur Phillip, who was given instructions authorising him to make regulations and land grants in the colony.[4] The ships arrived at Botany Bay between 18 and 20 January 1788[5]; HMS Supply arrived on 18 January, Alexander, Scarborough and Friendship arrived on 19 January, and the remaining ships on 20 January.[6][7]
passage: First Fleet
On 26 January 1788, the Fleet weighed anchor and sailed to Port Jackson.[26] The site selected for the anchorage had deep water close to the shore, was sheltered, and had a small stream flowing into it. Phillip named it Sydney Cove, after Lord Sydney the British Home Secretary.[44] This date is celebrated as Australia Day, marking the beginning of British settlement.[47] The British flag was planted and formal possession taken. This was done by Phillip and some officers and marines from the Supply, with the remainder of Supply's crew and the convicts observing from on board ship. The remaining ships of the Fleet did not arrive at Sydney Cove until later that day.[48]
