The Site is a complex of freshwater, brackish, saline and hypersaline wetlands found in stretches of coastal dunes and scrub. The suite of wetlands exemplify a process of shoreline advancement which is uncommon in southern Australia. The wetlands have been assessed to be in near-pristine condition, which is attributed to the remoteness of the Site. The Site supports at least 14 threatened plant species, four of which are endemic to Tasmania. It also supports threatened Tasmanian vegetation communities such as freshwater and saline aquatic herbland. Bird surveys have identified 12 wetland-dependent species and nine migratory species, including some that are nationally threatened. The area is used for livestock grazing. The Site is of spiritual and religious significance to the Tasmanian Aboriginal Community.
