WHS Due Diligence in 2026: What Australian Employers Must Do to Stay Compliant and Keep Workers Safe
Every year, thousands of Australian workers are injured on the job. According to Safe Work Australia, workplace injuries cost the national economy more than $28 billion annually — and behind every statistic is a real person, a real family, and in many cases, a preventable incident.
For employers, the message is clear: Work Health and Safety (WHS) compliance isn't optional, and it's not a box-ticking exercise. It's a legal, moral, and operational imperative.
Whether you're running a construction crew in Brisbane, managing a warehousing operation in Melbourne, or overseeing a manufacturing facility in Perth, your obligations under Australian WHS law are substantial — and the penalties for non-compliance can be severe.
This guide breaks down what employers need to know in 2026.
The Legal Framework: Model WHS Laws Across Australia
Australia operates under a nationally harmonised WHS framework, based on the Model Work Health and Safety Act developed by Safe Work Australia. Most states and territories have adopted this model legislation, including NSW (Work Health and Safety Act 2011), Queensland, South Australia, the ACT, the Northern Territory, and Tasmania.
Victoria and Western Australia have their own WHS legislation — the Occupational Health and Safety Act 2004 (VIC) and the Work Health and Safety Act 2020 (WA) — which align closely with the national model but contain some distinct requirements.
Regardless of jurisdiction, the core principle is the same: persons conducting a business or undertaking (PCBUs) must ensure the health and safety of workers and others, so far as is reasonably practicable.

Primary Duty of Care: What It Really Means
The primary duty of care under WHS legislation requires employers to:
- Provide and maintain a safe work environment
- Ensure plant, structures, and substances are safe
- Provide adequate facilities for workers (toilets, first aid, clean water)
- Provide information, training, instruction, and supervision
- Monitor worker health and workplace conditions
- Consult workers on health and safety matters
This duty extends not just to direct employees but also to labour hire workers, contractors, subcontractors, volunteers, and visitors to the workplace. If you engage workers through a labour hire services arrangement, both the host employer and the labour hire company share WHS responsibilities — a point that's often misunderstood.
Officer Due Diligence: Directors and Managers Take Note
One of the most significant aspects of Australia's WHS framework is the concept of officer due diligence. Under Section 27 of the Model WHS Act, company officers — including directors, CEOs, and senior managers — have a personal duty to exercise due diligence to ensure their organisation meets its WHS obligations.
This means officers must:
- Acquire and maintain up-to-date knowledge of WHS matters
- Understand the nature of their business operations and associated hazards
- Ensure their organisation has appropriate resources and processes
- Verify that incidents are investigated and learnings implemented
Ignorance is not a defence. Officers can face personal prosecution and significant fines even if they were not directly involved in a workplace incident.
Hazard Identification and Risk Management
At the heart of WHS compliance is a structured approach to managing risk. The hierarchy of controls — a concept mandated across Australian workplaces — provides a framework for reducing risk:
- Elimination — Remove the hazard entirely
- Substitution — Replace with something less hazardous
- Isolation — Separate the hazard from people
- Engineering controls — Physical barriers or mechanical aids
- Administrative controls — Safe work procedures, training, signage
- Personal Protective Equipment (PPE) — The last line of defence
Employers must document their risk assessments and Safe Work Method Statements (SWMS) — particularly for high-risk construction work as defined under WHS regulations. Failing to have current SWMS on site is one of the most common compliance failures identified by SafeWork inspectors.
Incident Reporting and Notifiable Events
All Australian employers are required to notify their relevant WHS regulator of notifiable incidents, which include:
- The death of a person
- A serious injury or illness (including hospitalisation, amputation, serious head or eye injury, or exposure to a hazardous substance)
- A dangerous incident (a near miss that could have caused death or serious injury)
Notification must be made immediately by the fastest means possible, followed by a written notification within 48 hours in most jurisdictions. The incident scene must also be preserved until an inspector clears it or 24 hours pass (whichever is sooner).
Failure to notify can result in significant penalties — up to $50,000 for an individual and $250,000 for a body corporate in some jurisdictions.
Consultation: Not Optional, Not Tokenistic
WHS law requires employers to genuinely consult with workers when identifying hazards, assessing risks, making decisions about risk controls, or introducing changes that may affect health and safety.
This includes recognising health and safety representatives (HSRs) and, where requested by workers, establishing health and safety committees (HSCs). Consultation is a two-way obligation — it means providing relevant information and giving workers a real opportunity to contribute, not just ticking a form.
Penalties for Non-Compliance
The financial and reputational consequences of WHS failures are serious. Under the Model WHS Act, Category 1 offences (reckless conduct causing death or serious injury) attract penalties of:
- Up to $3 million for a body corporate
- Up to $600,000 and/or 5 years imprisonment for an individual
Category 2 and Category 3 offences carry lesser but still substantial penalties. Beyond fines, employers can face enforceable undertakings, prohibition notices, and damaging media scrutiny.
As Infrastructure Magazine has reported, regulators across Australia are increasingly using sophisticated monitoring and data-sharing to identify non-compliant workplaces — particularly in construction and infrastructure sectors.
What This Means for Your Business
Employers across all industries should take these practical steps:
- Conduct a WHS audit at least annually to identify compliance gaps
- Review and update SWMS for all high-risk activities on a regular basis
- Train your officers and managers on their personal due diligence obligations
- Establish clear incident reporting procedures and ensure all supervisors know what constitutes a notifiable event
- Engage workers in genuine consultation — document it properly
- Review your labour hire arrangements to confirm shared WHS responsibilities are clearly defined and being met
If you're managing workers across construction staffing or logistics staffing environments, the risk profile is particularly high — and the regulator's attention is often focused there.
