About The Harbour Trust

Sub Base Platypus is managed by the Harbour Trust, a self-funding Federal Government agency established under the Sydney Harbour Federation Trust Act 2001.

The Harbour Trust’s mission is to preserve the natural and cultural heritage of our sites, and to promote them as places of leisure, enjoyment and interest for all Australians. Former defence sites that were off-limits to the public for many years are now open and free to visit all year round.

In addition to Sub Base Platypus, the Harbour Trust is responsible for the vision planning and management of:

  • Headland Park in Mosman (Chowder Bay, Georges Heights and Middle Head)
  • North Head Sanctuary in Manly
  • Cockatoo Island
  • Woolwich Dock and Parklands
  • Macquarie Lightstation in Vaucluse

The Harbour Trust invites you to experience some of the most beautiful urban parklands along the Sydney Harbour foreshore. We are focused on creating vibrant commercial and communal environments that activate our sites for everyone.
