Mackay, in Central Queensland, lies about mid way between Brisbane and Cairns and with a resident population around 71,400. The Mackay urban area, which is the focus of this study, is home to around 59,000. This study makes extensive use of Geoscience Australia's Risk-GIS method, which is a fusion of the decision support capabilities of geographical information systems, or GIS and the philosophy of risk management. The analysis of risk involves assessing the levels of hazard at Mackay, developing an understanding of the vulnerability of the elements which are at risk within the community and synthesising a range of event scenarios. A comprehensive building database is used to generate damage assessments for the various scenarios with each suburb ranked for its contribution to overall community vulnerability and for exposure to the various hazards. These two rankings determine total risk for each suburb by hazard, which allows the overall community risk from the various hazards to be compared.
