Great Australian Bight


The Great Australian Bight between Ceduna and Eucla is a globally significant breeding nursery for the southern right whale and for the Australian sea lion.

It’s also one of the only areas in the world where juvenile southern bluefin tuna are known to surface consistently, providing important feeding habitat for these critically endangered fish.

The cool waters of the Bight have exceptional diversity combining bottom-dwelling plants, seaweeds and sea sponges. These are just some of the 798 species of plants and animals that have been identified in the region, making it one of the world’s most diverse soft sediment ecosystems.
