Safe Work Australia: understanding your WHS obligations

If you're running a warehouse, manufacturing plant, or logistics operation in Australia, you're subject to some of the most comprehensive workplace health and safety legislation in the world. The model Work Health and Safety (WHS) laws, developed by Safe Work Australia and adopted (with variations) across most states and territories, set clear expectations about how you identify, manage, and monitor safety risks.

The challenge is that the legislation is deliberately broad. It tells you what you must achieve but gives you flexibility in how you achieve it. That flexibility is valuable for businesses, but it can also create uncertainty about whether your current approach is enough.

Here's what you actually need to know.

The numbers that make compliance non-negotiable

Before we get into the legal framework, the data provides important context for why this matters.

Safe Work Australia's Key WHS Statistics 2025 reports that 188 workers were fatally injured at work in 2024, with a fatality rate of 1.3 deaths per 100,000 workers. Vehicle incidents accounted for 42% of those fatalities (79 deaths), followed by falls from a height at 13%.

Beyond fatalities, there were 146,700 serious workers' compensation claims in 2023-24, involving at least one week of working time lost. That's more than 400 serious claims every day across Australia. Serious claims have increased by 34.5% over the past decade, and 80% of work-related fatalities and 61% of serious claims are concentrated in just six industries, including transport, construction, manufacturing, and agriculture.

The economic case is equally stark. Safe Work Australia's research estimates that eliminating work-related injuries and diseases would grow the Australian economy by $28.6 billion annually.

This isn't background noise. These are the numbers that drive regulatory enforcement and set the standard against which your compliance will be assessed.

What the model WHS Act actually requires

The model WHS Act establishes a primary duty of care for every person conducting a business or undertaking (PCBU). That duty requires you to ensure, so far as is reasonably practicable, the health and safety of your workers and anyone else who could be affected by the work being carried out.

In practical terms, this includes providing and maintaining a safe work environment, providing and maintaining safe plant and structures, providing and maintaining safe systems of work, ensuring the safe use, handling and storage of plant, structures and substances, providing adequate facilities for the welfare of workers, providing information, training, instruction, and supervision necessary to protect workers, and monitoring the conditions of the workplace and the health of workers.

The legislation also requires you to consult with workers on WHS matters, cooperate and coordinate with other duty holders who share the same obligations, and comply with the hierarchy of control measures when managing risks.

Officers of a PCBU (directors, CEOs, and senior executives who can significantly influence the business) have an additional duty to exercise due diligence. This means actively ensuring the PCBU meets its obligations, not simply assuming that someone else is handling it.

Understanding "reasonably practicable"

This phrase appears throughout Australian WHS law, and it's the standard against which your compliance will be measured. Safe Work Australia's guidance defines it as what is reasonably able to be done at a particular time, taking into account the likelihood of the hazard or risk occurring, the degree of harm that might result, what the person concerned knows or ought reasonably to know about the hazard and ways of managing it, the availability and suitability of ways to eliminate or minimise the risk, and after assessing the above, the cost of available ways to eliminate or minimise the risk (including whether that cost is grossly disproportionate to the risk).

That last point is critical for the technology conversation. If an effective, reasonably priced technology exists that could significantly reduce a serious risk, the "reasonably practicable" test may require you to consider it. The cost must be grossly disproportionate to the risk for it to be a valid reason not to act, which is a high bar when the risk involves serious injury or death.

The penalties for getting it wrong

The model WHS Act sets out three categories of offences with penalties that escalate based on severity.

Category 1 is the most serious: reckless conduct or gross negligence that exposes someone to a risk of death or serious injury. For bodies corporate, the maximum model penalty is over $3.3 million (indexed annually). For individual officers, it's up to $600,000 and five years' imprisonment.

Category 2 covers a failure to comply with a health and safety duty that exposes someone to a risk of death or serious injury, without the recklessness element. Maximum model penalties are approximately $1.6 million for bodies corporate and $300,000 for individuals.

Category 3 is a simple failure to comply with a duty, even where no one is exposed to serious risk. Maximum model penalties are approximately $550,000 for bodies corporate and $110,000 for individuals.

Several jurisdictions, including Queensland, have also introduced industrial manslaughter provisions, carrying maximum penalties of up to $20 million for bodies corporate and 20 years' imprisonment for individuals.

It's worth noting that penalties vary between states and territories, as each jurisdiction adopts the model laws with its own amendments and indexation. Victoria operates under separate legislation entirely (the Occupational Health and Safety Act 2004). Always check the specific requirements in your jurisdiction.

Recent changes you should know about

The WHS landscape in Australia is not static. In December 2025, Safe Work Australia released significant amendments to the model WHS Act, primarily expanding incident notification obligations.

The key changes include a new notification requirement for "relevant occurrences" (replacing the previous "notifiable incidents" framework), new categories for extended worker absences (15 or more consecutive days attributable to a work-related injury or illness), new notification duties for work-related suicide and attempted suicide, a broadened definition of "notifiable incident" that now includes "violent incidents" exposing workers to serious risk of psychological harm, and expanded definitions of serious injuries, covering a wider range of scenarios including bone fractures and certain head injuries.

These amendments haven't yet been adopted by all states and territories (that process typically takes one to two years), but they signal the direction of travel: broader reporting obligations, greater scrutiny of psychosocial risks, and higher expectations for how PCBUs monitor and respond to workplace events.

NSW has also introduced its own amendments in 2025-first!-understanding-the-2025-nsw-workplace-protections-amendments), strengthening Codes of Practice from guidance documents to enforceable minimum standards and expanding union powers in WHS matters.

Where Australian businesses commonly fall short

Working with Australian operations across warehousing, logistics, manufacturing, and cold storage, the compliance gaps tend to cluster in familiar areas.

Reactive monitoring only. Many businesses investigate safety after an incident rather than proactively identifying and monitoring hazards. The model WHS Act requires ongoing hazard identification and workplace condition monitoring, not just incident response.

Inconsistent coverage across shifts. Safety walks and audits conducted during business hours leave night shifts, weekends, and peak periods unmonitored. The duty of care doesn't switch off at 5pm.

Weak consultation records. The model WHS Act requires genuine consultation with workers on safety matters. If your safety programme is designed and delivered entirely by management, with no documented evidence of worker input and participation, you have a gap that a regulator will notice.

Under-developed leading indicators. Most businesses track lagging indicators (injury rates, lost-time incidents) and miss the leading indicators (near-miss rates, event trends, coaching completion) that actually predict and prevent incidents.

Insufficient documentation. When a regulator investigates, documentation is the primary evidence of compliance. If you can't demonstrate a systematic process of hazard identification, risk assessment, control implementation, and monitoring, your position is weak regardless of your intentions.

How technology strengthens your compliance position

Computer vision AI is directly relevant to the WHS compliance conversation because it addresses the specific gaps that regulators focus on.

Proactive hazard identification. The system detects safety events as they happen: pedestrian-vehicle near misses, exclusion zone breaches, speeding, PPE non-compliance. These are the hazards the model WHS Act requires you to identify and manage, captured continuously across every connected camera.

Continuous workplace monitoring. Unlike periodic audits, AI monitoring provides an unbroken picture of workplace conditions across every shift. This directly addresses the PCBU duty to monitor workplace conditions so far as is reasonably practicable.

Documented evidence trail. Every detected event is logged, classified by type and severity, and time-stamped. Reporting dashboards provide trend data, heatmaps, and shift comparisons that demonstrate your organisation is actively identifying and managing risks. This documentation is invaluable during regulatory inspections or investigations.

Worker consultation and engagement. inviol's coaching platform turns detected events into team coaching conversations. This directly supports your WHS obligation to consult with workers on safety matters and is far more effective than a suggestion box or an annual safety survey.

Privacy protections. A common concern with AI monitoring is worker privacy. inviol addresses this through face blurring, on-premise data processing, and SOC 2/ISO 27001/GDPR compliance. The system monitors risk, not individuals.

The "reasonably practicable" case for AI

Here's the compliance logic: if technology exists that can significantly reduce the risk of serious harm, at a reasonable cost relative to the risk, and you choose not to use it, the "reasonably practicable" defence weakens.

That doesn't mean every Australian business is legally required to implement AI safety monitoring today. But the bar is rising. As the technology becomes more accessible and more proven (inviol customers see an average 67% risk reduction), and as notification obligations expand to capture a wider range of events, the argument that traditional methods alone are sufficient becomes harder to sustain in high-risk environments.

inviol serves customers across Australia including Woolworths, Americold, and Linfox, all operating in the kind of high-risk environments where WHS obligations are most demanding. The platform is designed with Australian regulatory requirements in mind, including the specific consultation, documentation, and risk management frameworks set out in the model WHS laws.

What to do next

If you're an EHS manager, operations leader, or officer of a PCBU in Australia, these are the practical steps.

Review your current monitoring against model WHS Act requirements. Are you proactively identifying hazards across every shift, or only investigating after incidents? Is your workplace condition monitoring continuous, or limited to scheduled walks?

Assess your documentation. Would your records withstand a regulatory investigation? Can you demonstrate a systematic process of hazard identification, risk assessment, control implementation, and ongoing monitoring?

Check your consultation practices. Are workers genuinely involved in safety decisions, with documented evidence of their input and how it was acted on?

Consider whether technology could close your gaps. If you're running a high-risk operation with forklifts, mobile plant, or high-traffic pedestrian areas, computer vision AI may strengthen both your compliance position and your actual safety outcomes.

The businesses that take WHS obligations seriously before an incident are the ones that protect their people, their reputation, and their bottom line.

Frequently Asked Questions

What are PCBU duties under Australian WHS law?

A PCBU has a primary duty of care to ensure, so far as is reasonably practicable, the health and safety of workers and others affected by the work. This includes providing a safe work environment, safe systems of work, adequate training, monitoring workplace conditions, and consulting with workers on safety matters. Officers of a PCBU must also exercise due diligence.

What are the penalties for WHS breaches in Australia?

The model WHS Act sets out three categories of offences. Category 1 (reckless conduct) carries maximum model penalties of over $3.3 million for bodies corporate and $600,000 plus five years' imprisonment for individuals. Category 2 (duty failure exposing someone to risk) carries up to $1.6 million for bodies corporate. Several jurisdictions have also introduced industrial manslaughter provisions with penalties up to $20 million and 20 years' imprisonment.

What does "reasonably practicable" mean under Australian WHS law?

It means what is reasonably able to be done, taking into account the likelihood and severity of the risk, what's known about the hazard, available ways to eliminate or minimise the risk, and the cost of those measures relative to the risk. The cost must be grossly disproportionate to the risk to justify inaction, which is a high bar when serious injury or death is possible.

What changed in Australian WHS law in 2025?

Safe Work Australia released significant amendments to the model WHS Act in December 2025, expanding notification obligations to include extended worker absences (15+ consecutive days), work-related suicide and attempted suicide, and "violent incidents" causing serious risk of psychological harm. NSW also strengthened Codes of Practice to enforceable minimum standards. These changes signal broader reporting requirements and greater scrutiny of psychosocial risks.

How does AI safety monitoring help with WHS compliance in Australia?

Computer vision AI provides continuous hazard detection across every connected camera and shift, documented evidence of ongoing risk management, trend data for proactive decision-making, and coaching tools that support worker consultation obligations. These capabilities directly address core PCBU duties under the model WHS Act.
