Geographic range

It is found in the eastern Indian and western central Pacific Ocean in the waters off southern New Guinea, New Caledonia, and Australia (New South Wales, Northern Territory, Queensland, and Western Australia).^[1][2]

Adults may attain a total length of 105 cm (3 ft 5+3⁄8 in), with a tail 12 cm (4+3⁄4 in) long.
