The development of trauma systems in Australia has evolved over the last 18 to 20 years. Following a primarily North American model, nearly all the states and territories have identified and or implemented trauma system components to improve outcomes from injury. Trauma systems across the country are at varying stages of evolution, some are only in the early stages of development, and others are well established. As with most countries, multiple factors have influenced the development of trauma systems within each region. This study will provide an overview of the Australian Health System, initiatives implemented to reduce injury, the spectrum of trauma in Australia, and the current status of trauma systems development.
