Sea level rise and coastal erosion research

Summary of research

Climate change is increasing sea level rise and the associated risks of coastal erosion and inundation. This research was published by the NSW Government and research partners from 2008 to 2017. It provides information about how sea level rise may impact NSW coasts in the future, based on climate observations and projections, exposure and vulnerability characteristics specific to NSW, and examples of potential impacts based on previous king tide events. This information can be used by decision makers and planners to inform management and policies around coastal development and land use, and to help mitigate the impacts of sea level rise.
