 In Africa, the dusky dolphin ranges from Lobito Bay, Angola in the north to False Bay, South Africa in the south.Within Australian waters, dusky dolphins have been recorded in colder waters of Kangaroo Island, eastern Tasmania, and Bass Strait, although they are uncommon and those that are sighted there are possibly transients from New Zealand.They are also found around Campbell, Auckland, and Chatham in the western South Pacific, Tristan da Cunha in the South Atlantic and Île Amsterdam, and Île Saint-Paul in the southern Indian Ocean.
