Great Australian Bight

The Great Australian Bight is a large oceanic bight, or open bay, off the central and western portions of the southern coastline of mainland Australia.
The Great Australian Bight was first encountered by European explorers in 1627 when a Dutch navigator François Thijssen sailed along its western margins. The coast was later first accurately charted by the English navigator Matthew Flinders in 1802, during his circumnavigation of the Australian continent. A later land-based survey was accomplished by the English explorer Edward John Eyre.

The coastline of the Great Australian Bight is characterised by cliff faces (up to 60 metres (200 ft) high), surfing beaches and rock platforms, ideal for whale-watching. This is a popular activity during the southern hemisphere winter, when increasing numbers of southern right whales migrate to the region from their summer feeding grounds in the Antarctic. The whales come to the Bight region, especially to the Head of Bight, to calve and breed, and do not feed until they return to the Antarctic. Their numbers were severely depleted by whaling, particularly during the 19th Century, but have since recovered to some extent.

The Nullarbor Plain, which borders much of the length of the Bight's coastline, is a former seabed, uplifted during the Miocene. Consisting of limestone, it is very flat, and has an arid or semi-arid climate with very little rainfall, and high summer temperatures and high evaporation rates. It has no surface drainage, but has a karst drainage system through cave formation in the underlying limestone. North of the Nullarbor lies the Great Victoria Desert, which has an internal drainage system terminating in numerous small salt lakes.

There's a few lookouts across the Nullarbor which many people call into.
