Abstract
Geoscience Australia, in collaboration with the Department of Climate Change and Energy Efficiency (DCCEE), has conducted a preliminary study to investigate the risk posed to Australian communities by severe winds, both in the current climate and under a range of future climate scenarios. This National Wind Risk Assessment (NWRA) represents the first national-scale assessment of severe wind risk, using consistent information on residential buildings and severe wind hazard. The NWRA has produced an understanding of severe wind hazard for the whole Australian continent, including extreme winds caused by tropical cyclones, thunderstorm downbursts and synoptic storms. New modelling and analysis techniques have been applied to the results of Intergovernmental Panel on Climate Change (IPCC) climate modelling efforts to enable assessment of regional wind hazard to the end of the 21st century for four case study regions: Cairns, southeast Queensland, Hobart and Perth. In developing adaptation options, it is essential to have an understanding of the existing risk, and the risk at future times if no action is taken. Adaptation options can then be assessed on their cost versus benefit (i.e. reduction in risk). The NWRA presents methods by which the effectiveness of adaptation to improve residential building resilience may be assessed in economic terms. The study also recognises it is important that the outcomes of the risk analysis are communicated in such a way that the results are easily understood and utilised to support evidence-based policy.
