What it does
The Transport Safety Investigation Act 2003 establishes the Australian Transport Safety Bureau (ATSB) as Australia's independent multi-modal transport safety investigator. It governs the reporting of transport accidents and incidents, the no-blame investigation of those occurrences across aviation, marine, and rail, and the protection of safety information from misuse outside the safety context. The Act draws a sharp legal line between safety investigation and regulatory enforcement: a report under the Act is generally not admissible in civil or criminal proceedings, and on-board recording (OBR) information attracts strong protection from disclosure and admissibility.
The structure is clean. Part 1 contains preliminary matters. Part 2 establishes the ATSB and its governance. Part 3 deals with reporting of accidents and incidents. Part 4 governs investigations and reports. Part 5 contains the investigation powers. Part 6 protects OBR and other restricted information. Part 6A imposes reporting requirements. Part 7 contains miscellaneous provisions. The Act binds the Crown (section 4) and applies to External Territories (section 5) and to certain conduct outside Australia (section 6).
