Abstract
The Australian National Coastal Vulnerability Assessment (NCVA) was commissioned by the Federal Government to assess the risk to coastal communities from climate related hazards. In addition to an understanding of the impact/risk posed by the current climate, the study also examined the change in risk under a range of future climate scenarios. This assessment will provide information for application to policy decisions for, inter alia, land use, building codes, emergency management and insurance applications. Geoscience Australia coordinated the work undertaken to quantify the impact on property and infrastructure. This included the development of SMARTLINE, a nationally-consistent database of coastal morphology for the entire country, which provides critical information on the geology and landforms and their potential susceptibility to instability or degradation due to environmental or climatic factors. In a first-order attempt to assess the climate-change induced hazard to the coastal landscape, SMARTLINE data have been combined with sea-level rise (SLR) projections for 2030 and 2100, and 1 in 100 year current-climate storm surge estimates to determine potential areas of inundation and zones of instability where coastal recession due to SLR is predicted. Additionally, cyclonic wind hazard along Australia's northern coastline has been estimated using Geoscience Australia's Tropical Cyclone Risk Model, utilising synthetic tropical cyclone event sets derived from IPCC AR4 global climate models. The hazard levels have been modified for terrain, topographic and shielding effects to reflect localised variations in wind hazard.
