Great Australian Bight Facts
The Great Australian Bight is an open bay off of Australia's mainland. It is located off the southern coast's western and central regions. The Great Australian Bight was first explored by Europeans in 1627 when a Dutch ship reached its western margin. It was later charted by an English navigator in 1802. It is believed that the bight was created approximately 50 million years ago when Australia and Antarctica broke apart.
