The objective of the audit was to examine how efficiently and effectively the Australian Customs Service administers the Passenger Movement Charge, including the interim arrangements with airlines. The audit was intended to provide guidance to ACS on key issues and areas of risk it should address in developing the system supporting the collection of PMC. Audit criteria were determined to consider how well revenue was protected and how well the administrative arrangements were operating. The audit sought to identify areas for improvement in the formulation of longer-term arrangements.
