WHS Incident Reporting Obligations: What Australian Employers Must Do After a Workplace Incident

A serious incident at your workplace triggers immediate legal obligations. In the minutes and hours after an incident, you need to be doing three things simultaneously: ensuring the safety of people on site, preserving the scene where required, and notifying the relevant authority — within very tight timeframes.

Missing these obligations doesn't just compound the tragedy — it can result in significant additional penalties on top of any liability for the incident itself.

The Legal Framework

Work health and safety (WHS) incident reporting obligations are set by the Work Health and Safety Act 2011 (or equivalent state/territory legislation). All states and territories except Victoria and Western Australia have adopted the harmonised WHS laws. Victoria and Western Australia have their own legislation with broadly similar (but not identical) requirements.

Under the harmonised WHS model, the obligation to notify and preserve the scene falls on the person conducting a business or undertaking (PCBU) — which in practice means the employer or business operator.

What Must Be Reported?

The harmonised WHS laws distinguish between three categories of notifiable incident:

1. Death

Any death of a person resulting from a work-related incident — including a worker, visitor, contractor, or member of the public — must be notified immediately.

2. Serious Injury or Illness

A "serious injury or illness" must be notified immediately. This includes:

• Injury requiring the person to be admitted to hospital for immediate treatment
• Amputation (including degloving or scalping)
• Serious head injury, serious eye injury, or serious burn
• Injuries to the separation of skin from underlying tissue (degloving or scalping)
• Spinal injury
• Loss of a bodily function
• Serious laceration requiring surgery
• Any injury resulting in medical treatment within 48 hours of exposure to a substance

Note: "admitted to hospital for immediate treatment" means actual admission for treatment — not merely attending an emergency department and being sent home. If an employee goes to hospital, you should find out whether they were admitted. If in doubt, notify.

3. Dangerous Incident

A "dangerous incident" means an incident in relation to a workplace that exposes a worker or any other person to a serious risk to their health or safety from an immediate or imminent hazard. This includes:

• Uncontrolled escape, spillage, or leakage of a substance
• Uncontrolled implosion, explosion, or fire
• An uncontrolled escape of gas or steam
• Collapse, overturning, or failure of any plant
• Uncontrolled collapse or failure of any structure
• Electrical short circuit or explosion
• The fall or release of any plant, substance, or object
• Subsidence of any floor

A dangerous incident must be reported even if no one is injured. The obligation is triggered by the exposure to serious risk — not by the actual occurrence of injury.

Who Must You Notify?

You must notify the WHS regulator in your jurisdiction:

• New South Wales: SafeWork NSW
• Victoria: WorkSafe Victoria
• Queensland: Workplace Health and Safety Queensland
• South Australia: SafeWork SA
• Western Australia: WorkSafe WA
• Tasmania: WorkSafe Tasmania
• Northern Territory: NT WorkSafe
• Australian Capital Territory: WorkSafe ACT

If you have sites in multiple states, each jurisdiction has its own regulator and you must notify the regulator for each state where an incident occurs.

Notification Timeframes

| Incident Type | Notification Required | | ------------------------- | ---------------------------------- | | Death | Immediately after you become aware | | Serious injury or illness | Immediately after you become aware | | Dangerous incident | Immediately after you become aware |

"Immediately" in practice means as soon as the emergency response allows. The first priority is always to call emergency services and ensure people are safe. But you should notify the WHS regulator within hours, not days.

After the immediate notification, you must also provide a written notification to the regulator within 48 hours (some jurisdictions require this in written form on request; others require proactive written notification — check your jurisdiction's rules).

Preserving the Incident Site

After a notifiable incident, you must not disturb the site (or the plant or substances involved) unless:

• To assist an injured person
• To remove a deceased person
• It is essential to make the site safe for others
• A WHS inspector has given you permission

This prohibition is strict. Cleaning up, moving equipment, or resuming work at the site before you have permission from the regulator is itself a serious offence — even if the cleanup seems prudent.

You should cordon off the site, take photographs and video, and secure any equipment, materials, or substances involved. Do not touch anything that is not essential for safety or the removal of an injured person.

Internal Incident Recording

In addition to regulatory notification, you must maintain an internal incident register. All notifiable incidents must be recorded, along with:

• Date, time, and location
• Nature of the incident
• Names of people involved
• Witnesses
• Immediate actions taken

You should also maintain records of near-miss incidents — incidents that did not result in injury or significant damage but had the potential to do so. Near-miss recording is not a regulatory requirement for notification, but it is a WHS due diligence obligation, and regulators view the absence of near-miss records as evidence of an immature safety management system.

What Happens After Notification?

After you notify the regulator, they may:

1. Send an inspector — the inspector has broad powers to enter your workplace, inspect equipment, take photographs, seize evidence, and interview people
2. Issue improvement notices — requiring you to fix identified hazards within a specified time
3. Issue prohibition notices — stopping work until a specific hazard is controlled
4. Issue infringement notices — on-the-spot fines for certain offences
5. Initiate an investigation — which may result in prosecution

Cooperate with the investigation but take advice before making detailed statements — you have the right to legal advice, and early statements made without legal guidance can complicate your position.

Penalties for Failing to Notify

Failing to notify a notifiable incident is a serious offence under WHS legislation. Penalties include:

• For an individual: up to $10,000
• For a body corporate: up to $50,000

Deliberately concealing a notifiable incident to avoid notification can attract much higher penalties and potential criminal prosecution.

Post-Incident Investigation

After the immediate response, you must conduct a thorough investigation to:

1. Identify the root causes of the incident
2. Implement corrective actions to prevent recurrence
3. Review and update your WHS management systems

The investigation should be documented thoroughly. If the regulator investigates, your documented investigation demonstrates that you took the incident seriously and are committed to improvement.
