Located just North of Tathra Mimosa Rocks National Park covers an area of 5,802 ha and embraces 20 km of coastline. The park contains a diverse system of beaches, sea caves, headlands, cliffs, offshore stacks and lagoons. Spotted gums (Corymbia maculata) with an understorey of burrawangs are a feature of the park.
A number of threatened fauna species are found within the park including the sooty owl, golden tipped bat and hooded plover. The brown pigeon is found at the southern limit of its distribution.
Aboriginal people have occupied what is now Mimosa Rocks National Park for at least 6000 years. By that time, the sea had risen to its present level establishing a new range of hunting grounds including the Bega River estuary and three coastal lagoons either within or adjacent to the park.
It is, however, thought that Aboriginal occupation of the district could date back over the past 25,000 years. Today the major archaeological remains of this occupation are found in middens and open camp site deposits.
The estuaries and lagoons along the park's coastline also contain important wetlands. These are highly significant areas for nature conservation providing habitat and food for a range of waterbirds (both local and migratory).
In helping to maintain the ecosystems of the coastal lakes and lagoons, wetlands also play a vital role in protecting oyster habitat and the nursery grounds of prawns, and a range of commercial fish species.
Located just South of Tathra, Bournda National Park features the combination of ocean beaches, creeks, lagoons and the expansive waters of Wallagoot Lake. While the park is well serviced with camping and recreational facilities, its natural environment remains unspoiled.
The park has a rich history of Aboriginal occupation. It was an important food gathering place and evidence of hunting and tool making have been found in coastal middens and old camp sites.
The wetland areas around the mouth of Wallagoot Lake provide valuable habitat.
Threatened little terns breed on the northern side of Wallagoot Lake in most summer seasons. The site is fenced to protect the birds from disturbance. A team of shorebird volunteers assist the National Parks and Wildlife Service with monitoring and protection of the birds.
