Estuaries are waterways that extend from the tidal limit downstream to the ocean. The Hunter River Estuary (Hunter Estuary) is one of the largest estuaries in NSW, extending some 75 kilometres in land from the ocean. 

The Hunter Estuary is arguably one of the most complex estuaries to manage in NSW due to the different types of land use and ownership.

Estuaries are critical for the survival of many birds, animals, fish and other wildlife as they depend on these habitats to live, feed and reproduce. The Hunter Estuary provides a diverse range of habitats including saltmarsh, mangroves, wetlands, reed swamps and forested areas.  The Hunter Estuary is home to a high diversity of bird species, including seasonally migratory birds that are protected by international treaties (JAMBA and CAMBA).

The Hunter Estuary National Park is located within the lower portion of the estuary and covers an area of over 4000 hectares. The National Park includes Hexham Swamp, Stockton Sandspit and part of Kooragang Island. The National Park is the largest wetland reserve within a single estuary in NSW. Shortland Wetlands and part of the Hunter Estuary National Park are listed as a RAMSAR site, which means that these wetlands are of international significance.

The Port of Newcastle is also located in the Hunter Estuary. The Port is the largest coal export port in Australia and is of local and national economic significance. A range of other commercial activities exist within the estuary, including tourism, commercial and recreational fishing, and general industry.

An integrated approach to the management of the Hunter Estuary is required to protect and maintain its social, economic and environmental values.

A Fragile Ecosystem

Over the past 200 years, since European settlement, the Hunter Estuary has changed significantly with the introduction of mining, agriculture, urban areas and Port infrastructure. Changes to land use within the catchment have led to a number of impacts on the estuary, including a reduction in natural habitat and diversity, an increase in sediments and pollutants entering the estuary and changes to the flow patterns of the river.

Estuary Management

There are many stakeholders responsible for managing the Hunter Estuary, including private landholders, state and local governments, and Port related industries. Newcastle, Maitland and Port Stephens Councils, in cooperation with the State Government, are preparing the Hunter Estuary Management Plan to guide the future management of the estuary.

Hunter Estuary Management Plan

Councils are encouraged to develop Estuary Management Plans in accordance with the NSW Government’s Estuary Management Manual (1992).  The Estuary Management Manual outlines the steps required during the preparation of an Estuary Management Plan.

The Hunter Estuary Technical Working Party (previously the Hunter Coast and Estuary Management Committee) is responsible for the development and implementation of the Hunter Estuary Management Plan. The Working Party also provides advice to Council on strategic estuarine issues.

The Hunter Estuary Processes Study was completed by Manly Hydraulic Laboratory in 2003.

The Hunter Estuary Management Plan and Study were completed by BMT WBM in 2009.  The Hunter Estuary Management Plan contains management strategies to guide the future management of the estuary.
