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.
