Terrace, an unusually large expanse of terrace that lies between the continental shelf and slope; Nullarbor Canyon, a large elongated canyon that cuts through the terrace; D'Entrecasteaux Reef (also known as Iles des Martins and Iles Montenotte), an emergent reef in the north-east corner of the Marine Park; and Anna's Pimple, a cone-shaped volcanic pinnacle rising 200 m above the surrounding soft sediments in the southern part of the Marine Park at 1800 m depth.
The Marine Park includes habitats connecting to and complementing the adjacent South Australian Far West Coast and Nuyts Archipelago Marine Parks
Natural values
The Marine Park includes examples of ecosystems representative of:
  * Great Australian Bight Shelf Transition—a vast and shallow area, characterised by an extensive area of flat continental shelf. The invertebrate communities that inhabit the seafloor are among the most diverse in the world. The inshore areas of the bioregion are globally important for the threatened southern right whale and the Australian sea lion;
  * Southern Province—includes the deepest ocean areas of the Australian EEZ, reaching depths of around 5900 m, and that is characterised by a long continental slope, numerous, well-developed submarine canyons, and extensive mid-slope terraces such as the Ceduna Terrace.
Key ecological features of the Marine Park are:
  * Ancient coastline between 90 m and 120 m depth—high benthic biodiversity and productivity occur where the ancient coastline forms a prominent escarpment;
  * Benthic invertebrate communities of the eastern Great Australian Bight—includes soft-sediment benthic invertebrate communities of the eastern Great Australian Bight shelf, which form some of the world's most diverse soft-sediment ecosystems; and
  * Small pelagic fish of the South-west Marine Region—provides an important trophic link between plankton communities and larger fish-eating predators in this area.
The Marine Park supports a range of species including species listed as threatened, migratory, marine or cetacean under the EPBC Act. Biologically important areas within the Marine Park include foraging habitat for seabirds, Australian sea lions, white sharks and pygmy blue and sperm whales, and a calving area, migratory pathway and large aggregation area for southern right whales.
Cultural values
Sea country is valued for Indigenous cultural identity, health and wellbeing. Across Australia, Indigenous people have been sustainably using and managing their sea country for tens of thousands of years.
The Kokatha, Mirning, and Wirangu people have responsibilities for sea county in the Marine Park. The far west coast region of South Australia includes over 1000 km of coastline along the Nullarbor Cliffs of the Great Australian Bight and the Nyuts Archipelago, and supports a sea based tradition and culture.
The Mirning people have a strong connection to land and sea country of the Nullarbor, and the Wirangu people have a strong connection to
