Cockatoo Island (New South Wales)
In 1864 the island was split between the NSW Department of Prisons and the Public Works Department. The dockyard was made larger taking up most of foreshores. In 1869 the convicts were moved to Darlinghurst Gaol. In 1890 the Sutherland Dock, a dry dock large enough to take ships of 20,000 tonnes, was opened.
