Sub Base Stories Tour

Sub Base Platypus in North Sydney hasn’t always been a community recreation and work hub. Previously, the historic waterfront site hosted a gas works, torpedo factory and submarine base.  

From the late 1900s until the end of the 20th century, the site met the energy needs of Sydney’s North Shore (1877-1937) and contributed to the defence of Australia (1942-1999). Eager to journey through this layered history? book tickets to our all-ages Sub Base Stories Tour!

Running select Saturdays each month, this 60-minute tour is an opportunity to explore a historic destination that was off-limits to the public for 140+ years! Accompanied by a knowledgeable guide, you’ll explore the lower and upper levels of Sub Base Platypus, including the Torpedo Factory Precinct.

Unveiled in September 2023, this contemporary precinct boasts a decommissioned Mark VIII torpedo, amongst other historical artefacts, as well a sweeping view of neutral Bay and an original,three-piece artwork that celebrates Country.
