William Bradley was First Lieutenant on the ship, Sirius, captained by John Hunter. Contained in his journal are 22 meticulously drawn charts which record a series of early survey expeditions in the colony and voyages on the Sirius.
His sketch of the encampment in March 1788 is the earliest known map of Sydney. Written on the map are Bradley’s notes; “the position of the encampment & buildings are as they stood 1 March, 1788. The transports are placed in the Cove as moored on their arrival.” Bradley has marked the location of the Governor’s house and gardens, tents of the male and female convicts, the parade ground and marine encampment, along with other staples such as the stores and blacksmith locations.
