About This Unit
NAVAL BASE Sydney AUSTRALIA
HMAS Platypus is a former Royal Australian Navy (RAN) submarine base located on the harbour in Sydney.
HMAS Platypus was commissioned on 18 August 1967, conjointly with the Australian Fourth Submarine Squadron as the eastern Australian base for the six RAN Oberon class submarines. The first of the Australian Oberon class submarines, HMAS Oxley, arrived from the United Kingdom the day Platypus was commissioned into the Royal Australian Navy. Over its years of operation, Platypus has provided home base for Oxley (II), Otway (II), Ovens, Onslow, Orion and Otama, as well as HM Submarines Trump, Tabard and Odin.
Platypus, which was referred to as Plats by the ship's company, 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. While the submarines operated from the waterfront, the RAN’s torpedo workshops occupied the southern part of the site.
In 1999, HMAS Platypus and the torpedo workshops closed down when the Australian Government relocated its submarine base to HMAS Stirling in Western Australia with the entry of the Collins Class boats into service . HMAS Platypus was decommissioned on 14 May 1999.
