Report

South-west Corner Marine Park is the largest marine park in the South-West Network. The enormous park wraps around the south-west corner of Western Australia, enclosing Bremer Marine Park. It contains a wide range of important ecosystems in both shallow and deep water, reaching abyssal depths and including the Diamantina Fracture Zone, Naturaliste Plateau and Donnely Banks. These Key Ecological Features are unique seafloor structures that enhance productivity and support the high species diversity and endemism.

The park lies off the south-west corner of Western Australia, between Cape Naturaliste and Esperance. It covers 271,833 square kilometres, and has National Park, Habitat Protection, Multiple Use, Special Purpose (including Mining Exclusion) zones.Parks Australia

South-west Corner ranges from less than 10 to over 6,000 metres depth, with an average depth of 4,427 metres. The majority of the park (76%) falls within the abyssal zone (4,000-6,000 metres). [View on map] The mapped areas of the seafloor are dominated by Plane (39%) and Slope (27%) geomorphology. [View on map]
