The coastline of Victoria in its current form is under increasing threat. Coastal erosion, sea level rise, and increasingly extreme storm events are accelerating the rate at which the coastline of Victoria is changing. However, until recently, our understanding of these changes was severely limited by the absence of a long term coastal monitoring program in Victoria. To address this, the Victorian Coastal Monitoring Project (VCMP) was established in 2018 and has since been providing crucial data to inform coastal management and planning. Fundamental to the ability of VCMP to anticipate and prepare for future coastal change is high quality spatial data of the coastal zone. Together, Deakin University and Veris have integrated lidar and multibeam echo sounder data to create the Victorian Coastal Digital Elevation Model (VCDEM)—a seamless representation of the topography and bathymetry of the Victorian coastal zone. Veris recently updated the VCDEM to include new bathymetric products captured by Deakin University, Port of Melbourne Corporation and Gippsland Ports which will expand the capacity of VCMP to monitor and evaluate the Victorian coastal zone. Importantly, the recently updated VCDEM is available through permissive licensing arrangements, as well as the AusSeabed platform, which will broaden access to this fundamental data and increase the already diverse uses of VCMP data. Our recent updates to the VCDEM highlight the importance of high quality spatial data covering the coastal zone and will allow the VCMP, as well as existing and new stakeholders, to better understand and anticipate threats to the coastal zone and to help them drive the policy development to plan and manage them.
