Best accessed by boat from Tumby Bay or Port Lincoln, the park’s limestone-capped islands are havens for wildlife, providing refuge for diverse birdlife and the endangered greater stick-nest rat.

Access to some islands such as Dangerous Reef is prohibited, as they are important breeding colonies for sea birds and seals, while other islands provide ideal vantage points from which to view the marine animals that inhabit surrounding islands.

The Sir Joseph Bank Group Conservation Park lies within the Sir Joseph Bank Group Marine Park. Fishing, diving and other recreational activities are permitted other than within designated sanctuary zones which protect important marine ecosystems and marine fauna populations.
