We have applied new modelling and analysis techniques to develop a revised understanding of the regional wind hazard across the Tasmanian region. This modelling builds on downscaled global climate simulations from the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) over the Tasmanian region, undertaken by the Climate Futures for Tasmania project. These downscaled simulations enabled the development of wind hazard maps for the Tasmanian region both for current climate and also for two climate change scenarios. The wind hazard assessments (current and future climates) were used in a wind risk model to investigate the impact of severe wind risk on residential buildings. Australian Bureau of Statistics population projections were used to scale-up the number of residential structures based on the current ratio of residents per structure. The assessment of wind risk driven by the small increase in the hazard during the 21st century resulted in little or no change to the wind risk associated with the current residential building stock. When population projections were utilised to infer increased number of buildings (all built to the present building code), the proportion of legacy buildings within the building population declined resulting in a decline in wind risk. Wind risk levels remain well below those experienced in the northern part of the Australian continent were high wind hazard, chiefly associated with tropical cyclones, results in risk much greater than that experienced in Tasmania.
