This is a simple multi. Please be extra stealthy when retrieving the cache so it can have a long life.
From 1967, HMAS Platypus provided home base for six RAN Oberon class submarines, Oxley (II), Otway (II), Ovens, Onlsow, Orion, and Otama, as well as HM Submarines Trump and Tabard and Odin.
Platypus, was the only dedicated submarine base in Australia. Engineering workshops, medical facilities, the submarine school, communications centre and administration were all housed at the base providing the operational support required for the six submarines and their crews.
The Workshops building on the site was originally used for torpedo assembly and storage during WW2.
In 1999, HMAS Platypus and the torpedo workshops closed down when the Australian Government decided to relocate its submarine base to HMAS Stirling in Western Australia.
HMAS Platypus was decommissioned on 14 May 1999 and is now open to the public after 150 years.
This Multi will require you to take a walk around the completed precinct including the Torpedo Factory, Submarine School and Fleet Workshop.
There is limited parking available on the streets but the ferry ride from Circular Quay to North Sydney High Street is a delightful way to get here. Alternatively, there is now a new parking station dedicated to Sub Base Platypus.
Dogs on leashes welcome.
