The towering limestone cliffs lining the Great Australian Bight in South Australia are the Bunda Cliffs.
The Bunda Cliffs form a long coastal escarpment beside the Great Australian Bight, extending from Head of the Bight in South Australia westward to Eucla in Western Australia. They are also commonly called the Nullarbor Cliffs because the arid Nullarbor Plain lies immediately inland.
The cliff line extends for roughly 210 kilometers, including a largely uninterrupted section of about 160 kilometers. Many sections rise around 60 meters above the Southern Ocean. Geologically, the cliffs are made of fossil-rich Cenozoic limestone deposited in the Eucla Basin, rather than volcanic rock.
The Bunda Cliffs are often confused with other famous Australian formations, including the Twelve Apostles and the Three Sisters. Those landmarks are located in southeastern Australia and have different geological settings. “Bunda” is an Aboriginal word used in South Australia for the coastal cliffs, and the name was officially gazetted for the cliff line in 2014.
