Artist impression: Torpedo Factory Renewal Project

Torpedo Factory Renewal Project

Formerly a torpedo factory, submarine base and gas works, Sub Base Platypus is an emerging community recreation and work hub in North Sydney, homeland of the Cammeraygal people.

The Harbour Trust is currently delivering the Torpedo Factory Renewal Project, which will see further improvements to the site for the benefit of all Australians.

Torpedo Factory Precinct

Between July 2022 and September 2023, the Harbour Trust partially demolished the former factory and revitalised it as a sheltered public space. The new Torpedo Factory Precinct features a vantage point of Neutral Bay, a three-piece mural by Kamilaroi/Gamilaraay artist Dennis Golding, an event and storytelling space featuring historical artefacts, a car park with electric vehicle charging stations, rainwater capture storage and roof-mounted solar panels.

The Torpedo Factory Precinct will be officially opened to the public in September 2023. To celebrate, the Harbour Trust is hosting a community day on Saturday 16 September. Between 10am and 3pm, there will be a range of free activities at the new precinct, including a traditional Aboriginal performance, live music, talks, artmaking, guided tours and fun for kids. Plus, there will be gelato and hot food.

Wirra Birra Park

The Harbour Trust is now delivering the final stage of the Torpedo Factory Renewal Project: a new foreshore park.  Wirra Birra Park will be situated on the sandstone bench at the foot of the new Torpedo Factory Precinct and will provide visitors with a landscaped space where they can connect with Country and learn about native plants. The Harbour Trust looks forward to unveiling Wirra Birra Park to the public in late 2023.

Temporary carpark closure

The existing car park at Sub base Platypus (entry via 120 High Street, North Sydney) is currently closed to the public. The car park will remain closed until after Sub Base Platypus Community Day (16 September).
