About the Harbour Trust

The Harbour Trust protects and manages some of the most historically significant foreshore sites on Sydney Harbour, including Cockatoo Island, North Head Sanctuary, Sub Base Platypus in North Sydney, and Headland Park in Mosman.

Our sites are rich in history and connect Sydney to our complex past; from First Nations countries to convict incarceration, and from nineteenth and twentieth century military and defence roles to the enterprise and industry of Sydney’s working harbour.

Our role is to create new life on these historical sites, making vibrant new places with a mix of uses that Sydney-siders and visitors want to experience. We bring new life to our sites in a commercially sensitive and innovative manner, reinvest back into our sites to allow the public to access and enjoy these once inaccessible sites.
