Workplace Asbestos Obligations Under the WHS Act — A Plain-Language Summary

The legal framework in brief

Australia's workplace asbestos rules sit across two layers of law: the Work Health and Safety Act (the "WHS Act") and the Work Health and Safety Regulations (the "WHS Regulations"). Safe Work Australia developed the model versions, adopted with minor variations by most states and territories. Victoria has its own OHS Act, and WA harmonised in 2022.

The WHS Act sets out broad duties. The Regulations, specifically Part 8.1, contain the detailed asbestos requirements. Two Codes of Practice fill in the practical detail: "How to Manage and Control Asbestos in the Workplace" and "How to Safely Remove Asbestos."

What is a PCBU and why does it matter?

PCBU stands for "person conducting a business or undertaking." If you're a company, sole trader, government department, or body corporate that operates a workplace, you're a PCBU. The concept is deliberately broad, catching building owners, facility managers, tenants who control a workspace, and anyone who commissions work. Most asbestos obligations sit with the PCBU, not the worker or contractor (although they have duties too).

The duty to identify asbestos

Section 19 of the WHS Act imposes a primary duty of care on PCBUs to ensure, so far as is reasonably practicable, the health and safety of workers and others at the workplace. The WHS Regulations translate this into a specific obligation: if the workplace was constructed before 31 December 2003, the PCBU must ensure that asbestos or asbestos-containing materials are identified by a competent person (Regulation 422). In practice, this means commissioning an asbestos survey.

If you're unsure whether materials contain asbestos, you must assume they do until a competent person determines otherwise. The Regulations don't leave room for guesswork.

The duty to manage identified asbestos

Once asbestos has been identified (or assumed), the PCBU has a continuing obligation to manage it. This involves:

• Preparing and maintaining an asbestos register (Regulation 425)
• Developing an asbestos management plan (Regulation 429)
• Ensuring the register and plan are accessible to workers, health and safety representatives, and anyone doing work at the workplace
• Reviewing and updating both documents whenever circumstances change
• Monitoring the condition of identified materials on an ongoing basis

Managing asbestos doesn't always mean removing it. If material is in good condition, stable, and unlikely to be disturbed, leaving it in place with appropriate controls (labelling, encapsulation, regular condition monitoring) is a legitimate approach. The management plan documents how you'll handle each identified material.

Prohibition on use

The WHS Regulations prohibit the use, supply, and installation of asbestos and asbestos-containing materials at a workplace (Regulation 419). This applies to everyone. You cannot install new asbestos products, import them, or reuse salvaged asbestos materials. The prohibition has applied nationally since 31 December 2003.

Duties around removal

When asbestos needs to be removed, the Regulations set out requirements for licensing (Class A and Class B removal licences), notification to the regulator, control plans, air monitoring, and clearance inspections. The PCBU cannot delegate away their duty by hiring a contractor. Even when you engage a licensed removalist, you retain an obligation to ensure the work is done safely and that a clearance certificate is obtained before the area is reoccupied.

Worker duties

Workers must take reasonable care for their own health and safety, cooperate with reasonable instructions from the PCBU, and not interfere with safety measures. In practice, this means following safe work procedures, using required PPE, and reporting any suspected asbestos materials they encounter.

Penalties

The WHS Act creates a tiered penalty structure. Category 1 (reckless conduct creating risk of death or serious injury) carries maximum penalties exceeding $3 million for a body corporate, with individuals facing up to five years' imprisonment. Category 2 (failure to comply with a duty that exposes someone to serious risk) can exceed $1.5 million. Category 3 (general duty failure) maxes out at $500,000 for a body corporate.

Asbestos offences frequently attract Category 1 or 2 prosecution because the health consequences are well-documented and severe. Ignorance of the presence of asbestos is not a defence if the PCBU failed to carry out their identification duties.

Practical steps to stay on the right side of the law

For most facility managers and property owners, compliance comes down to a clear sequence. Get a qualified asbestos surveyor to identify what's there. Build your register. Write your management plan. Review both regularly. Before any renovation, demolition, or maintenance work that might disturb building fabric, check the register and engage appropriately licensed professionals. Keep records of everything. If in doubt, assume it's asbestos and get it tested.
