The Bunda Cliffs extend for 210 kilometres (130 mi) along the shore of the Great Australian Bight near its northern extremity.
The same formation extends from Eucla to Madura in Western Australia where it forms the scarp separating the Roe Plains from the Hampton Tableland, but in this section the coastline has moved away from the cliffs.
The Baxter Cliffs west of the Roe Plains are a further continuation of the escarpment, stretching for nearly 160 km along the coast.
The name was gazetted by the Government of South Australia on 2 October 2014 in response to a submission from the Department of Environment, Water and Natural Resources for approval to use it for a sanctuary zone in the Far West Coast Marine Park and refers to the extent of cliff line extending from the Western Australian border to the Head of the Bight.
Nullarbor Wilderness Protection Area extends eastwards from the Western Australia-South Australia border.
