The Bunda Cliffs are one of the most awe-inspiring sea cliffs in the world and are a dramatic display of the edge of the Australian continent. They will enchant the travellers’ eyes and make their visit utterly memorable. The limestone slab which forms the Nullarbor Plan and extends far inland has many layers. Some of those layers are made up of marine sediment and others incorporate marine fossils including worms and molluscs which indicate their marine origin. The sheer cliffs vary from 60m to 120m above sea level and are capped by a hardened layer of windblown sand laid down between 1.6 million and 100,000 year ago (text source: http://headofbight.com.au).
