Great Australian Bight Marine Park Whale Sanctuary is a protected area located immediately off the coastline of the Great Australian Bight in waters within South Australia about 790 km (491 mi) west-northwest of the Adelaide city centre. The whale sanctuary was originally proclaimed as a marine park under the Fisheries Act 1982 (SA) by the South Australian Government on 22 June 1995 to protect waters used by Southern right whales for breeding and calving . It was re-classified as an aquatic reserve after the repeal of the Fisheries Act 1982 by the Fisheries Management Act 2007 (SA) in 2007. It extends from 130 degrees 45.5 minutes east at its western boundary to 131 degrees 30 minutes east at its eastern boundary, and from the coastline for a distance of 3 nautical miles (5.6 km; 3.5 mi).
