The Harbour Trust’s vision is to create a landmark location for the people of Sydney. The revitalisation of Platypus will open up the fascinating spaces of this former industrial site for the first time in 150 years and will integrate the urban park with the surrounding neighbourhood.

The site was formerly a gasworks factory that was partially resumed by the Commonwealth Government as a torpedo manufacturing facility during WWII. In 1967 it became the base for the Royal Australian Navy’s Oberon Class submarines and was renamed HMAS Platypus.

In September 2003 the Federal Minister for Environment approved a comprehensive plan for the Harbour Trust’s sites. The Comprehensive Plan is a broad strategic plan which sets out a vision for the sites and includes a process for preparing more detailed management plans for specific places or buildings.

The former HMAS Platypus was included as an amendment to the Comprehensive Plan in May 2009.

Building on the overall vision established in the Comprehensive Plan, site-specific Management Plans were developed. They identify desired outcomes, including suitable land. HMAS Platypus is the most recent addition to the Harbour Trust. The Management Plan was approved in December 2016 and guides the revitalisation of the site as an urban parkland.

Consultation on the Platypus Management Plan took place between 12 August and 23 September 2016, to which Council made a submission.
