History and Country

Cammeraygal Country encompasses North Sydney, including the site of Sub Base Platypus, and this area was a historic source of food, shelter, medicine and tools for the Traditional Custodians.


Throughout the 19th and 20th centuries, the site hosted (at different times) a gas works, 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. When Sub Base Platypus officially opened in May 2018, Sydneysiders were provided with access to a new community recreation and work hub.
