The objective of the audit was to assess DIMIA's management of offshore measures to prevent and detect unlawful entry, and to identify opportunities for improvement. The audit did not cover the processing arrangements, referred to as the Pacific Strategy, introduced as part of the legislative changes in September 2001. Nor did it cover the range of measures use for prevention and detection at the border and on shore. As DIMIA is the lead agency responsible for the development of immigration policy, the audit focussed in the administrative effectiveness of the governance framework used by the department to implement and to support the achievement of Government strategies to prevent unlawful entry to Australian Territory.
