Great Australian Bight Marine National Park

The Great Australian Bight Marine National Park spans 1,233 square kilometers along the South Australian coastline, extending 3 nautical miles from shore.

The South Australian Government established this marine protected area in 1996 under the National Parks and Wildlife Act to safeguard marine ecosystems.

Mirning and Wirangu Aboriginal communities maintain traditional responsibilities for the marine territory within the national park boundaries.

Visitors can observe southern right whales from June to October at the Head of Bight viewing platforms, outside the restricted Marine Mammal Protection Area.

The waters support 80 percent of Australian sea lion populations, which dive to the seafloor hunting fish, squid, and small sharks.
