A forklift tips on a construction site in outer Brisbane. Nobody is hurt, but the site supervisor freezes for a second too long, unsure whether this counts as something SafeWork needs to know about. That hesitation, multiplied across thousands of Australian workplaces every year, is exactly why incident reporting requirements exist in such precise detail under Work Health and Safety (WHS) law.
Getting incident reporting wrong isn't just a paperwork slip. It can mean disturbing a site that should have been preserved for an inspector, missing a legal notification window, or failing workers who needed support after a traumatic event. For business owners, safety officers and HR teams across Australia, understanding exactly what must be reported, to whom, and within what timeframe, is one of the most practical compliance skills there is.
This guide walks through the current requirements, recent changes to the model WHS Act, and the everyday realities of running a reporting system that actually works.
What Counts as a "Notifiable Incident"?
Under the model WHS Act, persons conducting a business or undertaking (PCBUs) — a deliberately broad term covering employers, principal contractors, and many self-employed operators — must notify their WHS regulator immediately after becoming aware of certain serious events. These fall into three broad categories.
Death. Any fatality connected to the conduct of the business, regardless of where it occurs, triggers an immediate notification obligation.
Serious injury or illness. This includes injuries requiring immediate treatment as an in-patient in hospital, or treatment for things like serious burns, eye injuries, or substance exposure that may not show symptoms straight away.
Dangerous incidents. This is the category that catches people out most often, because no injury needs to occur at all. A dangerous incident is one that exposes a person to a serious risk to health or safety arising from immediate or imminent exposure. Common examples include the collapse of a trench, scaffold, or crane, an electric shock, an uncontrolled escape of gas or steam, a fire or explosion, or a heavy object falling from height.
That forklift tip-over from the opening scenario? If it exposed anyone — a worker, contractor, or even a passing member of the public — to a serious risk, it's notifiable, injury or not.
Why "Near Misses" Still Matter
A lot of confusion in workplaces comes down to one assumption: "nobody got hurt, so we don't need to do anything." Legally, that's only sometimes true.
A near miss that meets the dangerous incident definition above must still be reported to the regulator. A near miss that doesn't meet that threshold — say, someone slipping but catching themselves before falling — isn't notifiable externally, but good safety practice still calls for internal recording.
The reasoning is straightforward and well established across occupational safety research globally, not just in Australia: incidents that don't cause harm today are often warning signs for the incident that will cause harm tomorrow. Logging these patterns internally, even when there's no legal obligation to tell the regulator, is one of the cheapest and most effective ways to prevent a serious injury down the track.
Significant Changes to the Model WHS Act (December 2025)
This is where things get genuinely important for anyone responsible for WHS compliance in 2026. In December 2025, Safe Work Australia published amendments to the model WHS Act that expand notification duties considerably, addressing gaps identified during the 2018 statutory review of the model laws.
According to the Safe Work Australia handbook on notifiable incidents, the updated model introduces two entirely new notification categories sitting alongside the traditional "notifiable incident":
Notifiable Extended Absence
Under the amended model, a worker's absence becomes notifiable when it is reasonably attributable to a work-related physical or psychological injury or illness, and the worker has been off work for 15 or more consecutive days, or is expected to be based on a medical practitioner's opinion. Notification to the regulator is required within 14 days of this threshold being reached.
This is a meaningful shift. Previously, the regulatory focus was almost entirely on the moment of the incident itself. Now, a worker's recovery trajectory — including for psychological injuries like work-related stress or trauma — becomes part of the formal reporting picture.
Notifiable Suicide
For the first time, the model WHS Act explicitly defines a death by suicide, suspected suicide, or attempted suicide as potentially notifiable, where it occurs at the workplace (or a related workplace under the same PCBU's control) and at a time the worker would ordinarily be working. This change is widely seen as connecting directly to earlier reforms around psychosocial hazards and mental health duties, recognising that psychological harm deserves the same regulatory seriousness as physical injury.
A Word of Caution on Timing
Here's the part that trips up a lot of well-meaning safety managers: these changes are not automatically law everywhere. They amend the model WHS Act, which only takes legal effect in each state or territory once that jurisdiction formally adopts it into local legislation. As of early 2026, only the Australian Capital Territory has moved to adopt the additional requirements, with other jurisdictions expected to follow on their own timelines.
Victoria sits outside this process entirely, since it operates under its own Occupational Health and Safety Act 2004 rather than the model laws, and currently only requires reporting of serious injury or illness where medical treatment was actually sought — a narrower threshold than the updated model.
The practical takeaway: don't assume your jurisdiction's rules have changed just because the model has. Check directly with your relevant regulator — SafeWork NSW, WorkSafe Victoria, WorkSafe Queensland, or your local equivalent — before adjusting your internal reporting procedures.
What You Must Do When a Notifiable Incident Happens
Once an incident meets the notifiable threshold, a PCBU has several immediate legal obligations, not just a phone call to make.
Notify immediately. This typically means by the fastest practical means, usually a phone call to the regulator, followed by written confirmation, often within 48 hours.
Preserve the site. This is one of the most legally significant duties and frequently the one businesses get wrong under pressure. The site must not be disturbed until an inspector arrives or gives permission to proceed otherwise. The recent model amendments go further, extending this duty to cover preservation of evidence including electronic and digital records and witness details, not just the physical scene.
There are sensible exceptions. You can disturb a site to assist an injured person, to remove a deceased person with proper authority, or to make the area safe and prevent a further incident. Beyond that, moving equipment, cleaning up debris, or "tidying" before an inspector arrives can constitute a separate offence.
Notify your workers compensation insurer. Most jurisdictions also require separate notification to the relevant insurer, generally within a similarly tight window.
Keep records. Risk assessments, WHS management plans, and Safe Work Method Statements connected to a notifiable incident generally need to be retained for two years afterward.
The Real Cost of Getting It Wrong
Penalties for failing to notify are not symbolic. Under NSW law, for example, the maximum penalty for failing to notify a notifiable incident sits at $50,000 for a body corporate and $10,000 for an individual — and that's before accounting for any separate prosecution relating to the underlying safety breach itself.
There's also a less visible cost. A construction firm that disturbs an incident site before SafeWork arrives, even with good intentions, can find itself facing a far more difficult investigation, because key evidence about cause and contributing factors has been lost or contaminated. Investigators working from a preserved scene can usually establish root cause faster and with more confidence than those working from witness recollection alone — which matters enormously if the same hazard is sitting in five other branches of the same business.
Building a Reporting Culture That Actually Works
Compliance on paper is one thing. A workplace where people actually report incidents — including the awkward, embarrassing, near-miss ones — is another.
A few practices consistently separate organisations with strong reporting cultures from those with weak ones:
-
A clearly documented, simple internal process that any worker can follow without needing to interpret legislation themselves, paired with a named contact (not just a generic email inbox) for urgent notifications.
-
Regular, low-stakes training that normalises reporting near misses, rather than treating every report as a precursor to disciplinary action.
It's worth noting that a punitive culture is one of the most reliable ways to suppress reporting. If workers believe reporting a near miss will get them blamed, they'll quietly stop reporting, and the business loses its early warning system right when it needs it most.
A Quick Scenario Worth Thinking Through
Consider a mid-sized logistics company where a worker reports persistent shoulder pain after months of manual handling, eventually taking three weeks off on medical advice. Under the traditional model, this might never have crossed the regulator's radar unless it involved a single acute injury event. Under the amended model — once adopted in that worker's jurisdiction — this kind of extended, work-attributable absence could itself become a notifiable event.
For HR and WHS teams, this means the old habit of treating "the incident" and "the recovery" as two separate administrative processes is becoming outdated. They increasingly need to be tracked together, with absence duration flagged against the 15-day threshold as part of standard case management, not as an afterthought.
Staying Ahead of the Changes
Given how much is shifting — new categories, expanded site preservation duties, and a jurisdiction-by-jurisdiction adoption timeline — relying on outdated internal procedures or a one-off induction session from a few years back is a genuine risk. WHS regulators have made clear they expect duty holders to stay current, not to plead ignorance of changes that were publicly consulted on for years before being finalised.
For organisations wanting their safety officers, supervisors, and HR teams to handle this confidently — from correctly identifying a notifiable incident, to managing site preservation, to conducting a defensible internal investigation afterward — structured training closes the gap between knowing the law exists and knowing how to apply it under pressure. The Incident Reporting and Workplace Investigation Training course from Australian Compliance Training is built specifically around these real-world obligations, walking participants through notification triggers, site preservation duties, and sound investigation technique using current Australian WHS standards.
If your team has ever paused, like that site supervisor with the forklift, unsure whether something needs to go further, that hesitation is worth solving properly. You can explore the Incident Reporting and Workplace Investigation Training course here and equip your team with the confidence to act correctly the first time, every time.
