Ramsar Wetlands

Some 200 kilometres north-east of Darwin, the Cobourg Peninsula site on Australia’s northern coast encompasses all wetlands on the peninsula and nearby islands. It is large at 220,700 hectares, with diverse habitats and connectivity between its various wetland types. It incorporates seagrass, tidal flats, saltmarsh, mangroves, coral, beaches and dunes that support fish (including 14 at-risk marine fauna species), sea turtles and birds, including migratory waterbirds. The Arrarrkbi people, on whose country the wetland is located, uphold traditional land-management practices, customary law and traditions, and they jointly manage the site with government.

The diverse wetland of Moreton Bay is located within and around Moreton Bay, north-east, east and south-east of Brisbane. A site of 120,654 hectares, it is set in a semi-enclosed basin, with sizeable sand islands to its east and an estuarine coast to its west. The wetland includes freshwater, intertidal and marine areas, with creeks, bays, islands, beaches, mangroves, coral, seagrass and mudflats. These habitats support a range of wildlife species, including fish, turtles, dugong, crustaceans, seabirds and migratory shorebirds – regularly supporting as many as 50,000 waterbirds. The site is a popular location for boating, fishing and bushwalking, and a hub for tourism and seafood production.

Blue Lake is a 338-hectare site nestled in the Kosciuszko National Park, about 3.5 kilometres north-west of Charlottes Pass in the Australian Alps. A clear, freshwater lake with a depth up to 28 metres, it is the deepest of Australia’s four cirque lakes and was forged by glacial gouging of the granite bedrock. It is frozen for around four months each year. Blue Lake is a rare example of near-natural alpine wetland and is home to several species of at-risk flora, (including the Anemone Buttercup and Snow-wort) and endangered fauna, (such as the Mountain Pygmy Possum and Alpine Tree Frog.)

This 30,640-hectare Ramsar site is on the floodplain of an 80-kilometre stretch of the River Murray, between the South Australian town of Renmark and the state borders with Victoria and New South Wales. The area, which encompasses Chowilla and Ral Ral Creeks, provides habitat for several at-risk species, including Regent Parrot, Murray Cod, Murray River Turtle and Southern Bell Frog, as well as large numbers of waterbirds. In addition to supporting stock grazing and tourism, the Riverland is frequently used for bushwalking, fishing, camping and house-boating.
