The Site is a remote, undisturbed environment in Australia’s North West. It comprises a long section of coastline with intertidal mudflats and a saltmarsh with freshwater springs dated at more than 7,000 years old. The inland grey mangroves (Avicennia marina) in the Site are one of only two occurrences of inland mangroves in Australia. The area of the Site supports the largest numbers and greatest diversity of non-breeding shorebirds in the East Asian Australasian Flyway and is the first landfall for many birds on their southward migration from Asia. The saltmarsh supports breeding colonies for 13 waterbird species, including Australian pelicans (Pelecanus conspicillatus) and black swans (Cygnus atratus). The Site also provides habitat for the nationally vulnerable flatback turtle (Natator depressus) and green turtle (Chelonia mydas). There is a small camping area in the Site, where visitors engage in bird watching, fishing and shell collecting.
