Severe Wind Hazard Assessment for South East Queensland - SWHA-SEQ Technical Report
<div>The region of coastal South East Queensland (SEQ) is a large concentration of population, industry, and infrastructure important to the economy of Queensland and of Australia. The region is also subject to severe storms that generate damaging winds, particularly as result of thunderstorm and tropical cyclone activity. Older residential housing has historically been the most damaged in such storms, contributing disproportionately to community risk. This risk posed by severe wind is not well understood, nor are the optimal strategies for managing, and potentially reducing, this risk. In this hazard context, this project was initiated based on a joint proposal developed by Queensland Fire and Emergency Services (QFES), Geoscience Australia and the six coastal local governments in SEQ in January 2020. The objective was to gain an improved understanding of the wind risks in this region and to develop actionable information that could inform future strategies to manage and reduce risk in these areas, with broader application to other local government areas. The project proved to be of great interest to a broader range of stakeholders, including the insurance industry, some of whom became formal partners, while others participated as observers. </div><div><br></div><div>The management of wind risk requires a sound evidence base for decision makers. While the information developed in this project has significant uncertainties, the outcomes are considered a representative view of wind risk in a coastal region that is home to nearly 60% of the Queensland population. The work has developed an improved understanding of the three primary risk elements of wind hazard, residential exposure and vulnerability. This has been achieved through a broad collaboration that has entailed the sharing of data, domain expertise and consensus building. This, in turn, has been translated into an assessment of scenario impacts, local scale risk, and the nuancing effects of resilience on the outcomes. An exploration was carried out of the effectiveness of a range of retrofit strategies directed at addressing the residential buildings in our communities that contribute the most wind risk in South East Queensland. The outcome are expected to be a valuable resource for all the project partners and stakeholders in the areas of planning, preparation, response, recovery and strategic mitigation.</div>

This study was completed under the collaborative project Severe Wind Assessment for South East Queensland (GA Reference 005939) under a Collaborative Head Agreement with QFES (003039). Data related to age group and roof and wall materials for detached houses in the region was surveyed by Geoscience Australia. Aggregated data related to the same was obtained from industry partners under non-disclosure agreements. Scenario tracks for tropical cyclones were selected from GA’s Tropical Cyclone Hazard Assessment (TCHA) catalogue via the Tropical Cyclone Scenario Selector Tool (TC SST). Wind fields for scenarios were generated using the Tropical Cyclone Risk Model (TCRM). Models for selected house types were generated in terms of their structural systems and component strengths, and the wind vulnerability of these models were assessed using the software ‘Vulnerability and Adaptation to Wind Simulation’ (VAWS). The suburbs in the six partner Local Government Areas were catergorised for wind exposure based their age and material data in the National Exposure Information System (NEXIS) and supplemented by data from the 2016 Socio-Economic Indexes for Areas (SEIFA) from the Australian Bureau of Statistics. In assessing impact of tropical cyclone scenarios, the Australian Disaster Resilience Index (ADRI), developed by University of New England, was utilised. Statistically aggregated data from surveys was used to update NEXIS data for the relevant areas. (Severe Wind Hazard Assessment for South East Queensland)
