Edithvale-Seaford Wetland

The Edithvale-Seaford Wetland is the largest natural wetland of its type in the Port Phillip and Westernport basins. It is all that remains of Carrum Carrum Swamp, which once covered more than 4,000 hectares from Mordialloc in the north to Frankston in the south.

When European settlers arrived, this large wetland supported many animals and plants, including Brolga and Magpie Goose – now both extinct in the area. However, in the second half of the 19th century the wetland was gradually drained for farming and flood protection. In 1879 Patterson River was dug through the middle of the swamp to drain water into the bay.

The remaining wetland areas have been kept to provide flood protection, and include:

  • Edithvale Wetlands (101 hectares)
  • Seaford Wetlands (158 hectares)

A wetland of international importance

In 2001 the Edithvale-Seaford Wetland was listed as a Wetland of International Importance under the Ramsar Convention.

It was recognised because it:

  • is the last remaining examples of the Carrum Carrum Swamp, with a variety of permanent and seasonal, freshwater and salt water wetlands
  • supports populations of the Australasian Bittern, a bird of state significance and threatened in Victoria
  • supports more than 1% (2,000 birds) of the Sharp-tailed Sandpiper population that migrates along the East Asian-Australian flyway, in up to one year in three.

The management plan for the Edithvale-Seaford wetlands follows the Strategic Directions Statement for Management of Victoria's Ramsar Wetlands.

Birds and wildlife

It is estimated that at any one time, as many as 7,000 birds make the Edithvale-Seaford Wetland their home.

Star attractions include:

  • 190 bird species
  • 38 migratory species protected under international agreements and Australian legislation
  • migratory waders, including Latham's Snipe from the northern islands of Japan.

Seven bird species recorded at the Edithvale-Seaford Wetland are protected under the Flora and Fauna Guarantee Act 1988 (Vic):

  • Great Egret
  • Australasian Bittern
  • Baillon’s Crake
  • Lewin’s Rail
  • White-bellied Sea-Eagle
  • Australian Painted Snipe
  • Caspian Tern.

The wetland is also home to a mob of Eastern Grey kangaroos, and an extensive walking and bicycle track around its perimeter is ideal for birdwatching.


A recent  botanical survey of the Edithvale-Seaford Wetland mapped 14 plant communities, including three that are of state significance:

  • Plains Sedgey Wetland
  • Tall Marsh (Common Reed-dominated)
  • Brackish Aquatic Herbland.

The wetland also has a number of regionally significant plant populations, and one population of state significance: Large River Buttercup.

Economic and social values

As well as supporting animals and plants, the wetland is:

  • an important flood management asset
  • a popular community recreation facility, particularly for birdwatchers
  • a valuable education resource for school groups

Managing the wetland

We are responsible for managing Edithvale Wetlands, and manages Seaford Wetlands together with Frankston City Council.

The Friends of Edithvale-Seaford Wetlands are an active community group that helps us manage the wetlands.

Community liaison committee

The Edithvale-Seaford Wetlands Community Liaison Committee also plays a central role in planning and managing the wetlands. The committee was established in 2004 and includes representatives from environment, business and community organisations as well as local residents, members of the Friends of Edithvale-Seaford Wetlands group, and local government representatives from the City of Kingston and the City of Frankston.

The committee is a community engagement forum through which we aim to communicate effectively with interested stakeholders on matters relating to managing the wetlands. It aims to:

  • provide a forum to discuss issues relating to the ongoing and future management of the wetlands
  • identify potential actions and programs to enhance the wetlands’ wildlife and habitat features
  • promote and encourage scientific studies that will enhance the future management of the wetlands
  • advise on and assist in disseminating community information on the wetlands’ environmental, conservation and wildlife values.

For more information about the Edithvale-Seaford Wetlands Community Liaison Committee, please contact 131 722 and ask to speak to the local river health officer.

Edithvale-Seaford Wetland education centre

We constructed a Wetland Education Centre at the wetlands. It provides school students the opportunity to participate in practical, fun and hands-on activities.

Members of the public can also visit the centre every Sunday, between 1pm and 5pm. Responsibility for opening the centre each week alternates between Melbourne Water and the Friends of Edithvale Seaford Wetlands.
