 The ATSB is entirely separate from transport regulatory authorities such as the Civil Aviation Safety Authority (CASA), the Australian Maritime Safety Authority (AMSA) and the Office of the National Rail Safety Regulator (ONRSR), government policy makers and, service providers such as Airservices Australia and the Australian Rail Track Corporation (ARTC).This separation ensures the independence of ATSB investigations, thereby avoiding external influence and conflicts of interest.The "Transport Safety Investigation Act 2003" (TSI Act), allows the ATSB to investigate transport safety matters in the aviation, marine and rail transport modes within the Australian Government's constitutional jurisdiction and, to release transport safety information, including investigation reports that detail the findings and significant factors that led to a particular transport safety occurrence.
