It is the third line in the ‘3 lines’ assurance model that we use to monitor the operation of controls and risk-mitigation activities to assure the effective and efficient performance of our business processes. During 2023–24 our internal audit team performed 12 business audits, and 9 audits on compliance with the Civil Aviation Safety Regulations 1998.

All corrective actions arising from our internal audits are tracked, and their implementation progress is overseen by the Board Audit and Risk Committee.

During 2023–24 we were not the subject of any external performance audits by the Australian National Audit Office.
