Torpedo Factory Renewal Project

The Torpedo Factory Renewal Project will deliver a new foreshore park, heritage interpretation, public access improvements, and a welcoming entry to Sub Base Platypus, North Sydney...
Project overview

Sub Base Platypus is being transformed into a public park with its remnant buildings adapted for a range of cultural, recreational, community and commercial uses. The Harbour Trust has consulted extensively with the community about the site’s renewal as the former industrial and Defence complex has evolved into a public domain where historic spaces are revealed, interpreted and reimagined.

To date, renewal works have included the remediation of contamination, the demolition of some buildings and the adaptive reuse of others, the creation of public parkland, heritage interpretation, and improved public access including a new foreshore walkway, elevator and public car park.

The Harbour Trust is now focused on delivering the next stage of the site’s renewal by creating additional parkland through the adaptation and interpretation of the Torpedo Factory.

The proposal

In late 2020, the Harbour Trust proposed a new approach for the Torpedo Factory aimed at delivering new public parkland on the foreshore. To facilitate this, the Harbour Trust prepared a draft amendment to the Platypus Management Plan (Amendment 1) and a detailed Planning Application which were placed on public exhibition between 12 November and 11 December 2020. For further details and to view the documents placed on public exhibition, see Public Consultation.

The Consultation Overview and Consultation Outcomes Report below summarise the feedback received during the public exhibition:

In May 2021, the Members of the Trust considered the outcomes of this consultation along with feedback received from the Harbour Trust Advisory Groups, and approved the Platypus Management Plan (Amendment 1) and Planning Application. To view the adopted Platypus Management Plan (Amendment 1) and the Planning Approval Permit and Conditions of Consent, see Public Consultation.

Approval of the project followed referral of the proposed action to the Commonwealth Minister for the Environment, in accordance with the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). The Minister’s delegate determined under section 75 of the EPBC Act that the proposed action is ‘not a controlled action’, which means that it does not require further assessment and approval before it can proceed.
