Marmion Marine Park

The waters of Marmion Marine Park contain limestone reefs, caves, and lagoons extending five kilometers from the shore between Trigg Island and Burns Rocks.

Established on March 13, 1987, Marmion Marine Park became Western Australia's first marine conservation area, named after a pioneer who operated a whaling station.

The Whadjuk Aboriginal Corporation maintains a connection to this marine territory through joint management initiatives with local authorities.

Visitors access the marine park through Hillarys Boat Harbour or Ocean Reef, with designated areas for snorkeling, diving, fishing, and whale watching activities.

The Leeuwin Current brings warm waters to the park, enabling tropical marine species to thrive alongside resident dolphins, sea lions, and seasonal humpback whales.
