Along the shorelines of South-eastern Australia, there is concern that a lack of sediment supply, rising sea level and climate change will impact sediment circulation patterns, leading to the destabilization of nearshore-beach dune systems through erosion, overwash, and backshore transgression. We aim to explore the fundamental interconnectedness that drives shoreline change in Victoria, Australia. Despite the acknowledgment of coastal sediment dynamics being critical to sustainable management knowledge of shoreline behaviour and sediment movement is limited. The determination of sediment volume, type, quantity (i.e. extent and thickness) and morphology will be important to better understand the coastal sediment budgets and shoreline evolution. As a result the Victorian Government, t
