The Traditional Owners of the land encompassing Sub Base Platypus are the Cammeraygal. Their country extends from the west of Bradleys Head to the east of Lane Cove.

Prior to European colonisation, the local Cammeraygal People camped in sandstone caves on the harbour foreshore and lived on a diet of fish, possum and kangaroo, as well as native roots and berries.

From 1876 to 1932, Sub Base Platypus hosted a gasworks that supplied coal gas to residents and businesses on the North Shore. The site was dormant until 1942, when it was converted into a torpedo factory to supply the Allied navies in the South Pacific. 

In 1967, it was repurposed as a submarine base for the Royal Australian Navy’s Oberon-class submarine fleet.  Christened HMAS Platypus, the base operated for 32 years. 

In 2005, the Harbour Trust was granted stewardship of the site and tasked with transforming it into a public domain where historic spaces are revealed, reimagined and activated by cultural, recreational and commercial uses.
