This Inquiry Supporting Research Project (SRP) investigates how to better coordinate and use data for improved evidence-based decision-making at all levels of government in order to reduce the impact of disasters on housing. It addresses the Inquiry research question (IRQ3): How can the coordination of data and actors involved in the housing supply process be improved to support and drive the delivery of safer and disaster-responsive housing and communities? The project will deliver to policymakers a clear roadmap for better use of data to inform decision-making processes relating to new housing development planning and delivery. Better decision-making will help reduce, and even prevent, the impact of disasters, such as flooding, cyclones and bushfires, on housing and communities. Our research will also identify new policy settings needed to support such improved decision-making processes.
