Extensive consultation and strong community support is the keystone of the Sub Base Platypus Renewal Project. This process led to the Harbour Trust adopting a Management Plan (See: Planning framework) in 2016 that sets out a clear vision for the site’s renewal as a public park with buildings adapted for a mix of cultural, community and commercial uses. Income from reactivation of the site will contribute to maintaining Sub Base Platypus and other Harbour Trust parklands for public enjoyment.
The first stage of the project – an urban parkland featuring a scenic over-water walkway, BBQ area and pocket playground – has been completed, with the public granted access to these amenities in May 2018. The Australian Government and the Harbour Trust have jointly contributed $23.8 million towards the project.
