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

Southern Kangaroo Island ranges from 21 to 72 metres depth, with an average depth of 53 metres. The majority of the park (98%) falls within the mesophotic zone (30-70 metres) [view on map].

Based on annotations from publicly available seafloor imagery (Squidle+), the five most dominant seafloor categories in this Network are:

• Shallow: macroalgae (62%), unidentified (35%), unidentified biota (2%), soft substrata (2%), invertebrates (0%)
• Mesophotic: unidentified (33%), macroalgae (33%), soft substrata (11%), unidentified biota (11%), mixed invertebrate community (9%)
• Rariphotic: no public imagery available
