AbstractAn outline of sea‐level changes is presented, based on field work, bore‐log data, radiocarbon analyses, and a review of the literature. The sequence of eustatic changes, during and since the Pleistocene Epoch, is obscure in Australia, as elsewhere. Evidence suggests that the sea rose rapidly from 17,000 until 6,000 B.P., and that some deltaic plains and coastal depositional features along parts of the New South Wales and Queensland coasts formed since approximately 5,000 B.P. In the areas studied, there is not sufficient evidence to support a lo‐foot higher sea‐level which has been reported in Australia and attributed to a post‐glacial thermal maximum. A possibility of slight epeirogenic movement is considered in attempting to explain some coastal features in southern New So
