Great Sandy Strait Ramsar Site
The Great Sandy Strait Ramsar Site (GSS Ramsar site) was designated in 1999. It is a double-ended sand passage estuary receiving tidal flows from Hervey Bay in the north and Wide Bay in the south.
Situated partially within and between the Fraser Island World Heritage Area and the mainland coast it covers 93,160 hectares. Fresh water is delivered from a 1.25 million hectare catchment via rivers (Mary and Susan), creeks, coastal streams and the Cooloola sand mass to the comparatively small GSS Ramsar Site. Hydrological connectivity between adjacent areas, estuarine habitat and the upper reaches of the Mary River is a critical element that enables fish to move through riverine habitats for feeding or completing essential life-history migration.
The Outstanding Natural Values of the Great Sandy Strait
The GSS Ramsar site supports a large diversity of wetland habitats and a high number of wetland flora and fauna including nationally and internationally threatened species. It supports exceptional biodiversity of freshwater, estuarine and marine wetland fauna, including important populations of crustaceans, insects (butterflies), fish, frogs, marine turtles, shorebirds, terrestrial and marine mammals. The highest counts worldwide for the endangered shorebird, eastern curlew occur here. A variety of habitats within the GSS Ramsar site reflect a transition between tropical and temperate ecological zones.
A substantial area of non-forested peat swamp, comprised mainly of the rare ‘patterned fen’, occurs within the GSS Ramsar site. These fens together with areas of ‘wallum’ heath plains and swamps support species adapted to the prevailing acidic water and substrate including threatened frogs and fishes as well as species of crayfish and earthworm.
The GSS Ramsar site is of considerable cultural significance to indigenous Australians and contains natural resources that potentially may be harvested sustainably by indigenous people for traditional purposes. The site’s rich diversity and abundance of natural resources also supports a range of nature-based tourism and recreational activities as well as fishing.
Due to its significance the GSS Ramsar site is part of the Great Sandy Marine Park. A marine park zoning plan guides use and management.
BMRG Projects & Partners
Various threatening processes including pest plant and animal infestation, sedimentation, water quality decline and increasing urban development impact on the terrestrial and marine values of the GSS Ramsar site. On Fraser Island garden escapees from coastal townships threaten the integrity of surrounding the World Heritage Area. Through funding from the Australian Government, BMRG works with the community on projects to reduce threats and raise awareness of the importance of the GSS Ramsar site and the Fraser Island World Heritage Area.
