The Civil Aviation Safety Authority (CASA) is responsible for regulating aviation safety in Australia, the safety of Australian aircraft operating overseas as well as for regulating and administering Australia's airspace. In September 2008, the Senate Committee on Rural and Regional Affairs and Transport presented a report on the Administration of the Civil Aviation Safety Authority and related matters. That report made three recommendations, one of which requested an Australian National Audit Office (ANAO) audit of CASA's implementation and administration of the regulation of aircraft operators' Safety Management Systems (SMS'). ANAO agreed to this request with the objective of the audit being to assess CASA's implementation and administration of an SMS approach to regulating aircraft operators.

An SMS is a systematic approach to managing safety, which encompasses organisational structures, accountabilities, policies and procedures. Amendments to the Convention on International Civil Aviation (commonly referred to as the Chicago Convention) made in 2006 require that contracting states regulate the SMS' of aircraft operators. As a contracting state to the Chicago Convention, Australia is required to mandate that aircraft operators implement an SMS.
