The Bunda cliffs are part of a larger scarp of the Eucla Basin that spreads from the western part of South Australia across to the south eastern corner of Western Australia. As a geographical feature, they form part of the longest uninterrupted line of sea cliffs in the world. No other continent or country can match the cliffs for length of coastline.

The Bunda cliffs is an aboriginal name which has been used in South Australia for the name of the Nullarbor coastal cliffs. 

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 the name 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. 

The Bunda cliffs extend for around 100 kilometres (62 mi) along the Great Australian Bight near its northern extremity and are close to the Nullarbor Plain in a very sparsely settled area of Australia.
