Abstract
The submerged coast of south‐eastern Queensland is characterised by a series of depositional barrier features which include islands, spits, and beaches. Like much, of the eastern coastline of Australia, the barrier islands conform to a pattern of arcuate (zeta‐curved) bays between rocky headlands. They are distinguished by a complex series of ancient beach ridges with alternating swales, and fixed and mobile sand dunes, some of which attain heights exceeding 900 feet. The mode of origin of these islands and adjacent coastal deposits is still uncertain, but it seems probable that their development may be attributed to fluctuating sea‐levels associated with the Pleistocene and Early Recent phases of the Quaternary Era.
