HMAS Platypus Site

The Sydney Harbour Federation Trust (The Harbour Trust) is inviting public comment on the Platypus Renewal Project.

The $23.8 million Commonwealth Government funded project aims to implement a significant part of the Management Plan for Platypus.

The Management Plan sets out a vision to transform Platypus into a public urban park with its remnant buildings adapted for new uses.

The Management Plan was adopted in 2016 following extensive community consultation.

The renewal project includes the following works to enable the site to be opened to the public:

  • New public open space: creating new open space on the foreshore and facing High Street.
  • Access improvements: a new over-water pedestrian link to Kesterton Park, new lift and stairs between levels, limited new car parking accessed from High Street, and road safety improvements to Kiara Close,
  • Building renovation: base refurbishment of selected buildings to facilitate their future re-use.

Documentation about the renewal project is on exhibition until 16 August 2017, and is available via the Harbour Trust website.

The Harbour Trust is also organising the following drop-in information session:

Date: Thursday 3 August 2017

Time: anytime between 1pm – 7pm

Venue: Platypus Gatehouse, 118 High Street, North Sydney

Also, view the Harbour Trust’s notification letter (344KB).



The Harbour Trust’s vision is to transform the Platypus site into public open space and to adapt its buildings for cultural, recreational, community and commercial uses.

Platypus, on the foreshore of Neutral Bay, 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

Extensive community consultation on the Platypus Management Plan took place between 12 August and 23 September 2016.

Council at its meeting of 19 September 2016 resolved (Min. No. 302):

1. THAT Council resolve to support the general re-activation and adaptive reuse of the HMAS Platypus site.

2. THAT Council express concern regarding the unknown and potentially undesirable amount of commercial or other unsympathetic uses proposed for the site.

3. THAT Council seek clarification from Sydney Harbour Trust (SHFT) regarding the mix of Commercial and Community uses at the site.

4. THAT Council resolve to support development of access to the site in accordance with the contents of this report including a pedestrian link across Kesterton Park and creation of a shared way on Kiara Close.

5. THAT Council engage in discussions with SHFT to determine the suitability and practicality of creating community facilities and or activities on the Platypus site.

6. THAT Council seek an enhanced role in determining uses and activities on site.

7. THAT Council make a further submission to SHFT addressing the issues raised in this report.

8. THAT the City Strategy Division be the central point of contact for future interactions with the SHFT
