 Vivonne Bay is located on the south coast of the Kangaroo Island in South Australia overlooking the body of water known in Australia as the Southern Ocean and by international authorities as the Great Australian Bight about south-west of the municipal seat of Kingscote.Vivonne Bay has been described in an American source as being “a bight in the coast” between Point Ellen in the west and the Eleanor River in the east which is referred to as being the ‘Mary River’ and which is located about north-northeast of Point Ellen.While the American source does nominate an eastern extremity, the official Australian source does not.
