Sub Base Platypus Renewal Project

Sub Base Platypus in North Sydney is envisioned as a vibrant public domain with buildings and facilities adapted for a range of cultural, recreational, community and commercial uses.

In carrying out capital works to fulfil this vision, the Harbour Trust has consulted extensively with the community and endeavoured to preserve the heritage value of this former torpedo factory, submarine base and gasworks situated in Cammeraygal Country.


In 2005, the Commonwealth Government transferred the site to the Harbour Trust for the purpose of revitalising it as a public park. Due to signification site contamination – a holdover from the period when it served first as a gasworks and later as a Defence base – extensive remediation work was carried out by the Harbour Trust between April 2010 and April 2016. The Harbour Trust subsequently adopted a Management Plan (See: Planning Framework) to guide the revitalisation of the site, which was christened Sub Base Platypus in August 2017. In May 2018, the site was opened to the public for the first time in 150 years.
