The establishment of the park occurred between 1995-96 by combining the Great Australian Bight Marine Park Whale Sanctuary and the Great Australian Bight Marine National Park.
Southern Right Whale numbers are increasing though they are still far below 26,000 – the number of Southern Right Whales killed through whaling in Australian and New Zealand waters from 1820 – 1850 alone.
Late in summer the whales begin to leave their feeding grounds in the sub-Antarctic and migrate north to warmer waters. The journey is long and the whales will cover thousands of kilometres in a single trip. Each year between May and November the Head of the Bight is transformed into a marine nursery as the waters come alive with the activity of the visiting whales and their calves.
