The Nature Conservancy is leading Australia’s largest marine restoration initiative, the National Reef Building Project, to bring shellfish reef ecosystems back from the brink of extinction for the benefit of both people and nature. Hundreds of reef restoration projects conducted across the globe led by TNC and many others have demonstrated that shellfish reefs can be restored at scale and their benefits returned. We have decades of experience in building shellfish reefs all over the world, with many projects already well underway in Australia – Port Phillip Bay (Vic); Gulf St Vincent (SA); Noosa (Qld); and Oyster Harbour, Peel-Harvey Estuary and Swan-Canning Estuary (WA). Shellfish reefs are part of our national infrastructure, just like bridges and roads. They provide public benefits such as clean water and more fish. Rebuilding these reefs will help grow Australia’s ‘blue economy’ by providing a variety of coastal jobs in regional areas and sustaining marine-dependant industries like fisheries, aquaculture, retail, ecotourism and recreation. Over the next six years, together with governments, businesses and the community we aim to work with the community and restoration practitioners to protect and restore 60 shellfish reefs across Australia, making Australia the first nation in the world to recover a critically endangered marine ecosystem. This presentation will provide an overview of what we have done and how we will approach this bold initiative to rapidly expand the restoration and protection of valuable shellfish reef ecosystems.


Simon is particularly passionate about marine and coastal restoration – a passion informed by growing up fishing and diving in Queensland, spending many years of surfing throughout Australia and spending 15 years working in restoration in estuarine and coastal ecosystems.

Prior to joining The Nature Conservancy, he worked at the Victorian National Parks Association. He has also been on the Board of Directors for Surfrider Foundation Australia and as Chairperson for Environment Tasmania.

Simon’s main area of focus is restoration of shellfish reefs throughout East Coast Australia – bringing a endangered ecosystem back from the brink of extinction.
