History of Sub Base Platypus (Overview)

Prior to European colonisation, the Cammeraygal People camped in sandstone caves on the harbour foreshore. Throughout the 19th and 20th centuries, the site hosted (at different times) a gasworks, a torpedo factory and a submarine base. The Harbour Trust was granted stewardship of the site in 2005 and renamed it Sub Base Platypus in 2017.
