HMAS Platypus

18th August 1967 - 14th May 1999

Picture The motto said it all - "Nothing to Difficult" which many often misread as "Nothing, too Difficult".

HMAS Platypus was designed and built to provide base support for the six '0' Class submarines of the Royal Australian Navy. The base was built on ground which was formerly part of the Royal Australian Naval Torpedo Establishment in Neutral Bay, Sydney.
 
Unfortunately "Plats" has gone, and so has the relationships and sense of being that your own home provides. The submarines now operate from HMAS Stirling in Western Australia, not as a separate entity, but with the skimmers.

HMAS Platypus holds many memories, both good and bad, for Australian (and some RN) submariners (and the occasional skimmer that serviced and supported us) that served there over the years.

Over it's lifetime the site on which Platypus sat was contaminated by heavy metals, fuels and submariners and it was necessary to decontaminate the site before it could be made available to the public.  To get the full story on the remediation of the site and it's future visit the Sydney Harbour Federation Trust website at this link.

Below are images of the remediation works and as envisaged in the future (at the bottom of the page). The large structure over the retort building and where the admin building once stood, houses the remediation digging and coarse processing, which is then finished in the processing train that runs most of the length of the wharf to the vertical smokestack. The second image shows the excavations inside the enclosure
