Form Guidance

Defence Policy

Defence personnel are required to submit Defence WHS Events in accordance with Defence policy. All Work Health and Safety (WHS) Events related to employment in Defence, or as a result of a Defence undertaking, are to be reported using Sentinel. This includes WHS Events for all Defence employees, cadets and third parties (contractors and the general public).


The Work Health and Safety (WHS) Branch collects data on WHS Events under the Work Health and Safety Act 2011 and the Australian Radiation and Protection and Nuclear Safety Act 1998 (ARPANSA). Some Events require additional notification to the regulators, Comcare and ARPANSA.

Comcare Notifiable Events

Under Part 3 of the Work Health and Safety Act 2011 Defence has a duty to notify the regulator of defined notifiable events that have arisen out of Defence directed/controlled activities immediately after becoming aware that the event has occurred.

Notification in the first instance must be by phone - 1300 366 979. Seek advice from the Comcare contact regarding site preservation and submission of written notification of the event.

If the event has been identified as a notifiable to Comcare the event will be automatically submitted once the supervisor has completed the required supporting information in the event, in Sentinel.

WHS Report Completion

The Supervisor of the person involved, or reporting the event, is responsible for ensuring that all relevant sections of the WHS Event report are completed within the prescribed timeframes.

The role of Supervisor is assigned to the person who was supervising the Casualty/Casualties as at the time of the event and/or was in charge of the Defence work area at the time of the event.
