Colonies sampled in South Australia included those from Blefuscu, Lewis, Liguanea, Lilliput, Olive, and West Waldegrave Islands and three colonies from Kangaroo Island (Cape Gantheaume, Seal Bay, and Seal Slide). Coastal settlements and recreational locations within close proximity to sea lion colonies are indicated.
