Gippsland Lakes Ramsar Site is a large complex of coastal lagoons, estuaries, marshes and freshwater wetlands located on the southeastern coast of Australia in the state of Victoria. The site encompasses a network of interconnected waterbodies that include extensive habitats for migratory waders, endangered fish and diverse seabird and mammal assemblages, and is internationally recognized under the Ramsar Convention for its ecological values. It lies within the traditional lands of Gunaikurnai peoples and intersects contemporary local government areas such as the Shire of East Gippsland and Shire of Wellington.
The Gippsland complex comprises the principal waterbodies of Lake Wellington, Lake Victoria, Lake King, and the coastal lagoon system around Lakes Entrance and the Mitchell River mouth, together with associated swamps, saltmarshes and riparian zones. The designation as a Wetland of International Importance followed similar listings such as Coongie Lakes and Kakadu National Park under the Ramsar Convention. The site supports nationally and internationally important populations of species listed under instruments like the Environment Protection and Biodiversity Conservation Act 1999 and hosts habitats comparable to those protected in Narre Warren reserves and other Victorian wetland areas.
Gippsland Lakes occupies a low-lying coastal plain bounded by the Strzelecki Ranges and the Great Dividing Range foothills, drained by major rivers including the Avon River, Thomson River, and Snowy River via engineered channels and natural outlets. The hydrology is influenced by seasonal river inflows, tidal exchange through the artificial entrance at Lakes Entrance, and episodic marine inundation from the Bass Strait. Salinity gradients range from freshwater in riverine reaches to hypersaline conditions in closed lagoons during droughts, producing dynamic ecological zonation analogous to that found in Murray–Darling Basin floodplain wetlands. Sediment transport, channel morphology and barrier longshore dynamics are subject to modification from coastal engineering projects and catchment land use in Gippsland.
Flora includes extensive beds of mangrove-type saltmarsh, coastal reed communities, freshwater sedgelands and remnant Eucalypt woodlands that provide habitat for mammals such as Long-nosed Potoroo analogues and threatened species like the Growling Grass Frog. The lakes support important populations of migratory shorebirds protected under the CMS and the JAMBA, including species such as the Bar-tailed Godwit, Eastern Curlew and Red-necked Stint. Fish fauna comprises diadromous taxa including Australian grayling, estuary perch and common galaxias, while marine visitors such as bottlenose dolphins and occasional Humpback whales use the coastal entrances. Aquatic invertebrates, including crustaceans and molluscs, underpin productive food webs comparable to those in the Gulf St Vincent and support commercial and recreational fisheries for species like bream and flathead.
The site's Ramsar listing recognizes criteria for wetland types, waterbird populations and support for threatened species, aligning management with national instruments administered by the Department of Agriculture, Fisheries and Forestry (Australia) and state agencies such as Parks Victoria and the Victorian Environmental Protection Authority. Management frameworks integrate regional strategies developed by bodies including the Gippsland Lakes Taskforce and catchment organizations like the West Gippsland Catchment Management Authority and East Gippsland Catchment Management Authority. Conservation actions encompass habitat restoration, invasive species control, water regime management and community stewardship programs coordinated with Gunaikurnai Land and Waters Aboriginal Corporation and local councils such as the Baw Baw Shire. Monitoring and adaptive management draw on guidelines by the Ramsar Bureau and collaborations with universities including Monash University and the University of Melbourne.
Major pressures include altered hydrological regimes from river regulation and irrigation infrastructure linked to the Snowy Mountains Scheme, nutrient enrichment and eutrophication from agricultural runoff in the Latrobe Valley and urbanizing catchments, invasive plants such as Spartina anglica analogues and introduced fish and crustaceans. Climate change drives sea level rise and altered rainfall patterns affecting salinity and wetland extent, posing risks similar to those assessed for Yarra River estuarine systems. Coastal engineering, including training walls at Lakes Entrance and dredging, has modified sediment transport and habitat connectivity, raising conflicts among stakeholders such as commercial fishers, tourism operators in Lakes Entrance and conservation NGOs like the Australian Conservation Foundation.
The Gippsland Lakes region supports recreational boating, tourism centered on fishing and birdwatching, commercial fisheries and aquaculture enterprises, and is integral to the cultural heritage of the Gunaikurnai and European settler history associated with towns like Sale and Bairnsdale. Indigenous customary practices, seasonal resource use and cultural mapping have been incorporated into joint management arrangements exemplified by agreements with the Gunaikurnai Land and Waters Aboriginal Corporation and co-management in nearby protected areas including Gippsland Lakes Coastal Park. The area features in regional planning instruments administered by bodies such as the Victorian Planning Authority and contributes to local economies through events and nature-based tourism promoted by regional development agencies like Gippsland Tourism.
Ongoing scientific work includes avifaunal surveys by organizations such as BirdLife Australia and the RSPB collaborations, fisheries assessments by the Fisheries Victoria program, and hydrodynamic and water quality modelling conducted by research groups at Federation University Australia and the CSIRO. Long-term datasets inform adaptive management under state and federal plans, and citizen science contributions via platforms linked to eBird and local naturalist societies supplement formal monitoring. Research priorities address salinity management, habitat restoration effectiveness, climate resilience and integration of Gunaikurnai traditional ecological knowledge into scientific frameworks.
