Philip had been authorised to establish the intended penal colony by the Secretary of State for the Home Department, Lord Sydney. In reliance upon advice by botanist Sir Joseph Banks, who had accompanied Cook in 1770 (and after whom Botany Bay was named), Sydney had recommended that the colony be established at Botany Bay. Phillip landed in Botany Bay on 18 January 1788 but found the soil poor and fresh water scarce. He therefore went to the next inlet, Port Jackson, on 25 January 1788, Phillip wrote to the Secretary of State: “I fixed on a cove that had the best spring of water and in which the ships can anchor… close to the shore… This cove I honoured with the name of Sydney.” Phillip originally named the colony New Albion, after the archaic and oldest name for Great Britain, but that was quickly abandoned when the names “Sydney” and “Sydney Cove” continued to be used to refer to the colony as well as the Cove. Philip himself used those terms to head his official despatches to London.
