The objective of this audit was to examine the efficiency of the Australian Transport Safety Bureau’s (ATSB’s) investigation of transport accidents and safety occurrences.

The objective of this audit was to assess whether the Civil Aviation Safety Authority (CASA) has implemented effective arrangements for the planning and conduct of surveillance activities.

The audit followed-up the ANAO's original audit report into the aviation safety regulatory activities of the Civil Aviation Safety Authority (CASA) (Audit Report No.19 1999-2000 Aviation Safety Compliance). The objective of the follow-up audit were to determine, in respect of issues addressed by the original audit recommendations, whether CASA has made satisfactory progress to improve its aviation safety surveillance and compliance activities; and whether the introduction of new strategies for further improvement is being appropriately managed.

The audit reviewed the Australian Maritime Safety Authority's management of the navigation aids network, which is an important factor in shipping safety. The objectives of the audit were to determine whether AMSA's management of the network provides for the strategic needs of marine navigation in Australian waters, and whether AMSA's management was efficient and effective. The audit focused on AMSA's strategic planning, the management of revenue and expenditure to support the network, its contract management practices, and its accountability and performance reporting arrangements.

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.

ANAO found that the actions taken by the Department during the course of the audit to update and improve the Notes on Administration and administrative processes, by commissioning various specialist studies and reviewing governance issues, has established a sound basis for ongoing effective management of the National Highway System. The Department advised ANAO that changes to the Notes on Administration reflect joint work done with the ANAO to identify where improvements could be made and incorporate not only suggestions and recommendations that the ANAO has made in the final report but also during the audit. ANAO considers that the comprehensive revision of the Notes on Administration undertaken by the Department should foster marked improvements in the management of the National Highway System.
