Southern Kangaroo Island Marine Park features seasonal upwellings where currents and winds interact with seafloor features within its boundaries to produce a number of small upwellings that are important for biological productivity. These upwellings attract a myriad of marine life, including aggregations of small pelagic fish and higher trophic groups. The park is an important foraging habitat for Australian sea-lions, white sharks, and 11 seabird species, including fairy terns and black-faced cormorants.

Southern Kangaroo Island Marine Park lies off Kangaroo Island, 140 kilometres south-west of Adelaide and adjacent to the South Australia Kangaroo Island Marine Park. It covers 630 square kilometres and is a Special Purpose (Mining Exclusion) zone. – Parks Australia
