Each year, 'responsible persons', as defined in the Transport Safety Investigation Regulations 2003, Part 2.5, provide the Australian Transport Safety Bureau (ATSB) with reports on aviation accidents and incidents, collectively termed occurrences. These reports are used by the ATSB to assist with the independent investigation of occurrences and for identifying safety trends.

This report provides aviation occurrence data for the period 1 January 1999 to 30 June 2009. The data contained herein is dynamic and subject to change pending the provision of new information to the ATSB.

The data will be adjusted biannually to reflect new information received during the reporting period.
