A notifiable occurrence means an accident or incident associated with railway operations - either Category A, Category B or Category C.
Refer to the Reporting Requirements for Notifiable Occurrences for guidance on what is reportable and whether they are Category A, B or C.
(Note: Following changes to the Rail Safety National Law (RSNL) in July 2019, a separate report to the ATSB is no longer required.)
Ongoing trend monitoring of reported notifiable occurrences provides vital information for input into ONRSR’s risk-based regulatory decision making processes that inform its work program.
Details of the specific occurrences that must be reported are specified under Regulation 57 & Regulation 28 of the Rail Safety National Law National Regulations and provided below - read on for clarification and definitions.
