This report estimates that in 2018-19, up to $1.4 billion in health spending could have been avoided through improved injury prevention and management in sport and other forms of physical activity (12% of total injury costs). This includes estimating the contribution of specific forms of physical activity and sports to this spending. Information is presented on the web pages using interactive visualisations, and downloadable Microsoft Excel workbooks. Estimates of avoided health spending due to better health status from participation in physical activity will be released in a future publication.
