cies occurs in Australia and New Zealand. It is found in the coastal waters and on the offshore islands of southern Australia, from the south-west corner of Western Australia to just east of Kangaroo Island in South Australia, and also in southern Tasmania and the subantarctic Macquarie Island. Small populations are forming in Bass Strait and coastal waters of Victoria and New South Wales as far as the mid-north coast. Before the arrival of humans in New Zealand, the species bred around all the New Zealand mainland and its subantarctic islands. There are now established and expanding colonies around the entire South Island, on Stewart Island and all of the New Zealand subantarctic islands. There are also newly established breeding colonies on the North Island. Behaviour Diving The species can "porpoise" out of the water when travelling quickly at sea. They can dive deeper and longer than any other fur seal. Females can dive for about 9 minutes and to a depth of about 312 metres (1,024 ft), and can dive deeper and longer in autumn and winter. Males can dive for about 15 minutes to a depth of about 380 metres (1,250 ft). On average, the species typically only dives for 1–2 minutes. When they dive for food they dive deeper during the day but shallower at night, because during the day their prey typically migrates to deeper depths and migrat
