They (i.e. the three separate areas) provide an important habitat link between the coastal vegetation and inland mallee of the peninsula. The two large coastal blocks include low impact sandy beaches with an intertidal zone of mangrove and samphire communities. These communities provide habitat for shorebirds such as plovers, terns and the Sooty Oystercatcher which is listed as rare under the ''National Parks and Wildlife Act 1972''. Behind the coastal dune system are low open woodlands of Western Myall and False Sandalwood, with a Bluebush and Bladder Saltbush understorey. The mallee and saltbush associations contain populations of the Yellow Swainson-pea which is listed as vulnerable under the ''National Parks and Wildlife Act'' and the Dwarf Four-toed Slider which is listed as rare under the act.
