Understanding Incident Notification Requirements Under the Model WHS Act

22/08/2025by Isaac Patturajan0Read: 2 minutes

Workplace safety is more than just a legal responsibility, it’s giving people your best effort to protect them, to prevent harm, and to build trust. Under Australia’s Model Work Health and Safety (WHS) Act, workplace incidents defined as “notifiable incidents” must be reported to your relevant regulator without delay. 

What is Incident Notification?

Under the Model WHS Act, a person conducting a business or undertaking (PCBU) must notify the regulator as soon as they become aware of a notifiable incident.  

Notifiable incidents are when:

  • A person dies
  • A person suffers a serious injury or illness
  • A dangerous incident happens (a serious risk to health or safety even if no person is injured)

A phone call can be made to notify first, followed by a written notice, depending on your regulator’s processes.

When is an Incident Considered ‘Serious’?

‘Serious’ injuries and illnesses include any case that requires:

Immediate treatment as an inpatient in a hospital

Immediate treatment for:

  • Amputation
  • Serious head injuries or serious eye injuries
  • Serious burns
  • Spinal injuries
  • Loss of bodily function
  • Serious laceration

Medical treatment provided within 48 hours of exposure to a substance

Dangerous incidents are those that expose a person to a serious risk to health or safety, for example:

  • Uncontrolled spills, leaks, or escapes of substances
  • Electrical shocks
  • Explosions or fires
  • Structural collapse
  • Failure of plant, equipment, or pressure vessels

Preserving the Incident Site

When a notifiable incident occurs, the PCBU’s duty is to preserve the site until an inspector arrives or unless it would create a risk to someone, cause further damage, or assist an injured person so that they are no longer in need of assistance.

This duty preserves evidence so that investigators have an accurate record and understanding of what led to a person being made ill or injured at work.

State and Territory Variations

The Model WHS Act establishes a national framework, each state and territory regulator has its own specific procedures and contacts for reporting. Businesses must be aware of their local circumstances to remain compliant.

Why Timely Notification Matters

Failure to notify the regulator of a notifiable incident is a breach of the WHS Act and could result in costly penalties. In addition to compliance, prompt notification will help with the following:

  • Protect workers and the general public
  • Promptly identify and control hazards
  • Prevent future incidents
  • Protect your organisation’s safety reputation
