Report

Perth Canyon Marine Park includes the majority of the Perth Canyon, Australia’s largest submarine canyon, which is home to the largest feeding aggregations of blue whales in Australia. Perth Canyon was shaped by the ancient Swan River system on land, and today links the shelf to deep-water ecosystems.

Perth Canyon is located 19 kilometres west of Rottnest Island, offshore from Perth. It covers 7,409 square kilometres, and has National Park, Habitat Protection and Multiple Use zones.Parks Australia

Perth Canyon ranges from 141 to 4,810 metres depth, with an average depth of 2,399 metres. The majority of the park (38%) falls within the lower-slope zone (2,000-4,000 metres). [View on map] The mapped areas of the seafloor are dominated by Slope (40%) and Plane (34%) geomorphology. [View on map]
