Our region is home to a beautiful coastline. It is a source of industry and recreation, and provides unique coastal and marine habitats for many native plants and animals. The South East Natural Resources Management Board is committed to ensure it is protected for future generations to enjoy through a variety of past and current projects and educational campaigns. The Limestone Coastwatchers program is a great example of a project making a difference to the future of our coasts and marine life.
Coastal Action Plan
A plan has been developed to understand and facilitate the conservation, protection and maintenance of the region’s natural coastal resources and to establish conservation priorities for action for places and areas within the region. The plan has been uploaded into several parts.

The Limestone Coast and Coorong - 10 amazing facts!
- Limestone Coast is home to many unique plants, such as the Little Dip Spider Orchid, and animals found nowhere else and provides a range of habitats such as freshwater lakes & wetlands, expansive dune systems, and intertidal reefs.
- The marine life of South Eastern Australia is more diverse than the Great Barrier Reef with an amazing diversity of sea algae and marine creatures and is home to the prized Southern Rock Lobster.
- It is home to the largest and smallest mammals on earth: the Blue whale and the microbat, Little Forest Bat (Vespadelus vulturnus) which is found in the SE and weighs only 3-6.8 g (less than the weight of a 10 cent piece). This little critter would easily fit inside a matchbox!
- It is an ‘end station’ for feathered international aviators (migratory shorebirds), with some migratory shorebirds flying here from as far as Siberia and Alaska every year along the East Australasian flyway.
- There are over ten coastal parks and reserves (totalling 25,000 Hectares) to ensure protection of the unique Limestone Coast for future generations to enjoy.
- The South East has four highly valued marine parks with five marine sanctuaries contained within them.
- There are no natural rivers in the South East, yet the Limestone Coast is unique for its diversity of coastal wetlands. Some are fresh water some salt water. The Limestone Coast was thought to rival Kakadu for wetlands and wildlife prior to draining the land for agriculture.
- In karst wetlands, which are very rare in Australia, water rises from limestone beneath the surface. Water comes out of the ground in two or three very large springs, some springs 110 metres deep into the karst limestone. The spring water rising from the karst system is very clear because it has been filtered through limestone for many kilometres, over a very long time. Piccaninnie Ponds is just one of many local examples of these fascinating karst rising springs.
- The deep blue briny is rich in marine creatures. Southern right whales are observed in bays along the coast as they migrate along our shores and back to Antarctica. Australian and New Zealand Fur seals and sea lions breed on one of the small islands found near Robe. The Limestone Coast is also a migration route for Humpback and Blue whales.
- The Limestone Coast is closer to the edge of the continental shelf than anywhere else in Australia, which is one reason why the Bonney upwelling occurs here. It is the upwelling of cold nutrient rich waters that makes the coastal waters so biodiverse and productive.
Common indigenous plants of the Limestone Coast
- Coast Beard-heath, Leucopogon parviflorus
- Drooping Sheoak, Allocasurina verticillata
- Coast Daisybush, or Wild Rosemary, Olearia axillaris

- Coastal Wattle, Acacia longifolia var. sophorae
- Hairy Spinafex, Spinafex sericeus
The Coastal Planting Guide shows how to use the variety of native local plants in your garden. An extensive list of the flora and fauna along the coast can be found in the Coastal Action Plan.
