The objective of this audit is to assess Customs and Border Protection's processing of incoming international air passengers in the primary line, in particular the extent to which: (a) systems and controls effectively support the referral of incoming air passengers who pose a risk and those carrying prohibited items; (b) air passengers presenting an immigration risk are processed appropriately; and (c) Customs and Border Protection has arrangements in place to effectively promote co-operation and information sharing between Customs and Border Protection and DIAC.

The objective of the audit was to assess the administrative effectiveness of Australian Customs Services (Customs) drug detection strategies for air and containerised sea cargo and small craft activity. Within the scope of the audit, the following areas were examined :

• intelligence and law enforcement cooperation;
• air and containerised sea cargo;
• cargo examinations and technology;
• small craft activities;
• Customs funding arrangements (including funding for NIDS initiatives): and
• governance, including performance reporting.

The objective of the preliminary study was to form a view regarding the quality of, and controls over, the Budget estimates and to inform the decision whether to proceed to a full performance audit at this time. On the basis of the quantitative and qualitative analysis of the budget process undertaken during the study, the ANAO concluded that there are no apparent systemic problems in the cash-based estimating processes in the agencies reviewed that would, in themselves, lead to material statistical inaccuracies in the Budget's projected outcomes. The ANAO decided not to proceed with a full performance audit at this time.
