General Marine Park Information

The Southern Kangaroo Island Marine Park weighs in at 673km2 and covers the southern coastline of K.I. between D'Estrees Bay and the western boundary of the Seal Bay Conservation Park (near Vivonne Bay). It also has an offshore component, encompassing North Rock, Young Rock and South West Rock.

This section of the coast is characterised by long, high-energy sandy beaches and dune systems with cliffs and rocky headlands breaking up the beaches. Shallow and deepwater reefs are present as well, and provide a barrier to the seas of the Southern Ocean in places. Some seagrass beds exist in sheltered spots along the eastern border of the marine park near D'Estrees Bay.

The sandy beaches are home to a large colony of sea lions and fur seals and is one of the premier tourist destinations of Kangaroo Island. The Seal Bay Conservation Park has a boardwalk running along sections of the beach and primary dune system where a visitor can get quite close to these enormous mammals, and even the occasional pup!
