17 lighthouses catalogued on the South Australia coast.
South Australia's lighthouse history is the history of wheat. The ports of the Yorke and Eyre peninsulas shipped millions of tonnes of grain in the 19th and early 20th centuries, and every shoal and reef between Cape Jaffa and Eucla needed to be marked. The state also operated some of the most remote lighthouses in Australia, including the isolated Neptune Islands and the still-manned (until 1992) Cape Willoughby on Kangaroo Island.
