Australian Aboriginal Traditions about Coastal Change Reconciled with Postglacial Sea-Level History: A First Synthesis.

Like some other oral traditions of Australian Aborigines, those that relate to widespread and enduring coastal inundation appear to be several thousand years old. The best-documented traditions, some mythologised, are presented for six sites around the Australian coast (Bathurst and Melville Islands, Northern Territory; Rottnest, Carnac and Garden Islands, Western Australia; Spencer Gulf, South Australia; Kangaroo Island, South Australia; Port Phillip Bay, Victoria; Cairns and Fitzroy Island, Queensland). The minimum depths at which each tradition would have been true is determined from local bathymetry. These depths are then compared to postglacial sea-level history and minimum ages for each tradition calculated. These range from 7,500-13,400 years Before Present and represent unique observations of postglacial sea-level rise and its effects that have significant implications for an appreciation of the longevity of such traditions in preliterate societies.
