Red-necked wallabies, swamp wallabies, grey kangaroos, possums and marsupial mice all live in the park. If you're lucky, you might also see nocturnal brush-tailed phascogales and sugar gliders if you're camping at Arakoon.
Birds are abundant in this area. In the park's wetland areas, you might see black swans, egrets, herons and spoonbills. On the heath, there are fantails, wrens, honeyeaters and quails. Hawks, falcons, ospreys and eagles soar above the cliffs and forage along the beaches.
During the spring, when the she-oaks fruit, glossy-black cockatoos come in to feed on the ripe seeds. These birds are endangered in New South Wales, and this is a rare chance to see them in their natural environment. Listen out for their raucous call.
