Sydney was founded in 1788 by Captain Arthur Phillip, commodore of the First Fleet in Royal Navy, who was sent to Australia from England to establish a penal colony. He was sent by home secretary Thomas Townshend Sydney. He landed first at Botany Bay 8 km to the south but, for several reasons, found it unsuitable for settlement. Phillip continued north to Port Jackson, which he described as ‘the finest natural harbour in the world’ in a letter to the home secretary, Thomas Townshend Sydney, after whom the city was named. He landed at Sydney Cove on 26 January 1788. The settlement of Sydney grew at Sydney Cove, becoming known simply as “Sydney”.
