Which Australian peninsula separates Spencer Gulf from the Great Australian Bight?

The Eyre Peninsula is the Australian peninsula separating Spencer Gulf from the Great Australian Bight.

It occupies the western side of South Australia and is named after explorer Edward John Eyre, who crossed the region in 1840–1841. The peninsula has a long coastline, dry interior landscapes, agricultural districts, and important fishing ports. Port Lincoln is its largest city and a major centre for seafood and farming.

The eastern coast faces Spencer Gulf, while the western and southern coasts open onto the Great Australian Bight and the Southern Ocean. Coffin Bay, Lincoln National Park, and the Gawler Ranges are among the area’s notable natural features.

Eyre Peninsula is commonly mixed up with Yorke Peninsula, which lies farther east and projects into Spencer Gulf. Eyre is the larger western landform. Its name is also sometimes misspelled “Eyre’s Peninsula,” but the standard geographic name is Eyre Peninsula.
