The ATSB maintains its own database, the Safety Investigation Information Management System (SIIMS), in which all reported occurrences are logged, assessed, classified and recorded. The information contained within SIIMS is dynamic and subject to change based on additional and/or updated data.

Occurrences are those notifications received by the ATSB that are assessed to meet accident and incident definitions for the purpose of entry into SIIMS. The legal basis for this assessment changed from 1 July 2003 with the introduction of the Transport Safety Investigation Act/Regulations 2003.

Transport safety occurrence data

Each year, the ATSB receives thousands of reports on accidents and incidents, collectively called occurrences, across the rail, marine and aviation transport modes.

We use this occurrence data to prioritise independent investigations and to identify trends in transport safety.

Statistical report format

The ATSB has changed the way in which aviation statistics are presented. All statistics will be incorporated in a report and can be opened for viewing or downloaded. The report encompasses a rolling 10-year reporting cycle and replaces all individual spreadsheets previously available on the ATSB website. The data will be updated annually.

Non-VH registered recreational aircraft data are not included in these statistics.

The report contains the following data:

a. Aviation activity (hours flown and departures) by aircraft operation types (within commercial air transport and general aviation)
b. Number of aviation accidents, serious incidents, incidents, fatal accidents, and serious injury accidents by aircraft operation types
c. Accident rates and fatal accident rates per million departures and/or hours flown by aircraft operation types
d. Accident rates, fatal accident rates, and fatalities by aircraft type (aeroplanes and helicopters)
e. Accidents and serious incidents, and incidents by occurrence type events (what happened) by operation type

Feedback: If you have any comments relating to the format of aviation statistics, the ATSB would be interested in hearing from you. Please direct your comments to atsbinfo@atsb.gov.au with the subject header of 'Aviation statistics - feedback'.


The Bureau of Infrastructure, Transport and Regional Economics (BITRE), Aviation Statistics section (Avstats) routinely collects activity data for general aviation and commercial operations that include:

  • hours flown
  • aircraft type
  • statistical grouping

Hours flown data for rate calculations provided by the BITRE are only available up to 2006.
