The Derwent Estuary Program is a partnership between state and local government, industry, researchers and the community to restore and promote our Estuary. We share science for the benefit of nature, the economy and the community.

Where is the Derwent Estuary?

The Derwent Estuary, located in southern Tasmania, Australia, extends from the rural river town of New Norfolk south to the Iron Pot lighthouse. The estuary is a unique environment – a partially enclosed body of water where tidal seawater and fresh river water mix. The sheltered waters of the estuary support unique habitat and species specifically adapted to life in this environment.

Education and protection

Our vision for the Derwent is an estuary with a healthy and diverse ecosystem that supports a wide range of recreational and commercial uses and is a source of community pride and enjoyment. Our mission is to work together to understand the Derwent Estuary system, to take action to progressively enhance and protect the estuary’s values, and to inform and involve the community in this process. We conduct regular water quality monitoring through our Beach Watch program. We work with the community to reduce litter. We monitor heavy metals in the Derwent, provide resources relating to stormwater and encourage water sensitive urban design. We have also developed a range of educational resources focused on key estuary habitats and species.

We would like to pay respect to the traditional and original owners of this land, the Tasmanian Aboriginal people — to pay respect to those that have passed before us and to acknowledge today’s Tasmanian Aboriginal people who are the custodians of this land.
