The topographical formations now known as Garden Island and Potts Point first became recognisable features in the Sydney Harbour landscapes about 6,500 years ago when sea levels stabilised at their current levels. The Cadigal people came to know them by the names of Ba-ing-hoe and Derawan.Attenbrow, 2002. In June 2004 the NSW Government announced an initiative to reintroduce a dual naming policy for such significant landforms. Over the following few thousand years, the harbour's Aboriginal population gradually increased, developed significant technologies (such as fish-hook making), raw material utilisation (such as recovering shells for tool making), and maximised estuarine food resources from rocky shorelines, such as shellfish.
