Results of regional geological studies on the southeastern Australian coast and inner continental shelf suggest that broad relationships between nearshore sediments and morphologies are often the result of factors other than incident waves and wave-induced currents. Five main factors (including wave action) have been identified: 1. degree of compartmentization and sand bypassing, 2. incident wave energy, 3. offshore sand loss to deep water sinks, 4. inherited sediment characteristics, and 5. substrate control. It is thought that these factors have controlled coastal evolution in the past and also influence present-day coastal changes. Identification of the role played by individual factors in specific areas provides valuable information on coastal sediment budgets.
