Lies within the Myall Lakes National Park and includes the Corrie Island and Little Broughton Island Nature Reserves. One of the few coastal brackish lake systems in New South Wales which has not been greatly modified by human activities. The area is renowned for the diversity of its plant species and its complex variety of habitats, which is largely due to differences in substrate. It is home to a number of threatened species, such as the endangered Australasian bittern (Botaurus poicloptilus) and the endangered green-thighed frog (Litoria brevipalmata), as well as the vulnerable Freycinet’s frog (Litoria freycineti) and stuttering frog (Mixophyes balbus). The Dark Point dune sheet, comprised of sand dunes up to 50 metres high and covering about 250 hectares of the Ramsar Site, is estimated to have moved between 38 and 54 metres since 1999 through a natural process.
