Investigation reports

Where a critical industry or causal investigation is commenced an Investigation Information Release (IIR) is published (generally within 14-21 days) to share early learnings. A final report is published at the conclusion of the investigation.

The final reports provide information useful for a risk assessment, cause and circumstance of the incident, findings, and the actions taken after the incident.

Learning from investigations videos

Investigation reports may include incident animation videos as additional resources. All Learning from investigations videos can be viewed on the Regulator YouTube channel.
