Triangular inlet of the Indian Ocean, southeast Australia.
It is on the coast of South Australia between Yorke Peninsula and the mainland. About 90 mi (145 km) long and 45 mi (73 km) wide, it is linked to the ocean by the Investigator Strait and the Backstairs Passage. Kangaroo Island lies across the gulf's entrance, and Port Adelaide (pop., 1996: 37,559), South Australia's leading port, is on its eastern side.
