Rediscover the Harbour Trust's sites during our 20th anniversary year

arrow Read: Commemorative DigiTales (NEW)
This year marks the 20th anniversary of the Harbour Trust, established in 2001 to protect heritage sites in Sydney, share their diverse stories, and enable you to enjoy rich experiences on the world’s best harbour…

For 20 years (and counting), we’ve sought to leave a legacy for all Australians by collaborating with passionate communities and firmly weaving our visitor destinations into Sydney’s cultural fabric.

Our 20th anniversary celebrations will commence on 20 March to commemorate the date when our founding legislation was presented to Parliament. From 20 to 29 March, the community can enjoy Rediscovery Days: a program of FREE tours and talks – plus special events and promotions by our tenants – that showcase the natural and heritage values of our protected sites. Our 20th anniversary celebrations will culminate in September, to commemorate when the Sydney Harbour Federation Trust 2001 was proclaimed.

PLUS: Read our 20 Things to Do blog to discover the breadth of experiences across our visitor destinations and look out for articles commemorating our 20th anniversary.

Sandra Hall: Veteran Volunteer

In the 20 years since the Harbour Trust was established, our heritage sites have emerged as rich sources of intrigue and exploration, beloved by many Australians. For their contribution, we owe a debt of gratitude to the hundreds of volunteers who have generously shared their time, knowledge and passion. In this DigiTale, veteran volunteer Sandra Hall reflects on her journey with the Harbour Trust and celebrates the diversity of our volunteer team.

Voices of our Volunteers

"I’ve been incredibly fortunate to have served as Harbour Trust Volunteer Manager since 2003 and have witnessed or played a part in a number of great initiatives. Many of these undertakings would not have been possible without our amazing team of volunteers. The Harbour Trust has benefitted greatly from their unique perspectives, special skillsets and length of service. This DigiTale shares the stories of some of the volunteers we’ve been privileged to work with." – Volunteer Manager
