Two Rocks Marine Park protects unique inshore lagoon habitats that are key areas for benthic productivity and the recruitment of rock lobster and reef fish species. It is also an important foraging habitat for several species of seabirds.

The park is 25 kilometres north-west of Perth and the Western Australian Marmion Marine Park. It covers 882 square kilometres, and has National Park and Multiple Use zones.Parks Australia

Two Rocks ranges from 18 to 14 metres depth, with an average depth of 50 metres. The majority of the park (71%) falls within the mesophotic zone (30-70 metres). [View on map] The mapped areas of the seafloor are dominated by Plane (95%) and Apron (2%) geomorphology. [View on map]
