HSRs and Risk Management

Under the Work Health and Safety (WHS) Act, duties are not transferable. The primary duty to manage health and safety risks remains with the person conducting a business or undertaking (organisation) at all times, supported by its officers (directors) through the exercise of due diligence. This principle sits at the core of the legislation and shapes how all other roles operate within a WHS management system.

At the same time, the WHS Act deliberately embeds worker participation through consultation and representation. One of the key mechanisms for this is the role of the Health and Safety Representative (HSR). HSRs are given specific powers, including the ability to inspect workplaces. Their role is not to manage risks, but to represent workers’ interests and to verify that WHS arrangements are working in practice.

Understanding how these elements fit together is essential. HSR powers do not dilute or displace the PCBU’s obligations. Instead, they form part of a broader framework designed to ensure risks are identified early, worker concerns are heard, and safety systems are tested against real‑world conditions.

Duties under the WHS Act remain with the PCBU

The WHS Act assigns responsibilities clearly and deliberately:

• PCBUs hold the primary duty of care to ensure health and safety so far as is reasonably practicable

• Officers (including directors and senior managers) must exercise due diligence to ensure the PCBU complies

• Workers and others must take reasonable care for health and safety

• HSRs are not duty holders

  
  

There is no mechanism under the WHS Act for the business to pass its risk management obligations to an HSR. If risks are not adequately managed, responsibility remains with the organisation and its officers — regardless of the level of HSR involvement. HSR activity may inform decision‑making, but it never replaces legal accountability.

Why HSRs have inspection powers

HSR inspection powers are often misunderstood because they can look similar to management activities. However, their purpose is fundamentally different. HSRs are empowered to inspect workplaces so they can:

• represent the health and safety interests of workers

• identify hazards raised by workers in their work group

• verify whether controls are actually in place

• assess whether WHS systems are working in practice

• raise and escalate unresolved issues through consultation

These powers exist to support representation, verification and escalation — not to enable HSRs to manage or approve risk controls. Put simply: HSRs inspect to question and verify, not to control or decide.

Inspection is not "risk management"

Managing WHS risk involves:

• identifying hazards

• assessing risks where required

• selecting and implementing controls

• reviewing and maintaining those controls

These activities sit squarely with the PCBU, supported by officers through "due diligence." HSR inspections, by contrast, focus on:

• visibility of hazards experienced by workers

• checking whether stated controls exist in reality

• identifying gaps between procedures and practice

• ensuring worker concerns are formally raised

The WHS Act intentionally separates:

• responsibility for managing risk, from

• authority to represent and challenge

This separation strengthens the WHS system by preventing conflicts of responsibility while ensuring meaningful consultation.

Do HSRs conduct risk assessments?

HSRs do not conduct risk assessments in the legal sense. HSRs:

• do not approve risk assessments

• do not sign off on SWMS or safe work procedures

• do not determine what is “reasonably practicable”

• do not carry liability for the adequacy of controls

  
  

However, HSRs are entitled to:

• identify hazards during inspections

• ask questions about risk assessments

• request access to WHS information

• challenge controls they believe are ineffective

• suggest controls based on worker experience

This role supports consultation and verification — it does not transfer responsibility for risk decisions.

Why the WHS Act is designed this way

The structure of the WHS Act reflects long‑standing regulatory experience. Regulators recognise that:

• workers often identify hazards before management does

• formal systems can miss day‑to‑day operational risks

• workers may be reluctant to raise concerns without protection

• consultation fails when it is superficial or procedural

HSRs exist to address these issues by providing:

• a protected worker voice

• access to information

• inspection rights

• escalation pathways when consultation fails

This is also why trained HSRs have limited enforcement powers, such as issuing Provisional Improvement Notices (PINs) or directing unsafe work to cease where there is a serious and immediate risk, and only when consultation on the matter has failed. These powers are safeguards, not transfers of duty.

Officers and due diligence

Officers play a critical role in ensuring this framework works as intended.

Due diligence requires officers to:

• ensure appropriate WHS systems are in place

• ensure resources and processes are available

• ensure hazards and risks are being addressed

• verify that controls are effective in practice

HSR inspections may provide valuable insight, but they do not satisfy due diligence obligations on their own. Officers must actively seek assurance and cannot rely on HSR activity as a defence.

Explaining the boundaries clearly

Clear language helps prevent confusion in workplaces. Two statements that accurately reflect the law are:

HSRs do not manage risk — they represent workers and verify that risk is being managed.

and

HSR inspections provide visibility and voice, not responsibility.

Using language like this helps avoid:

• PCBUs relying on HSRs to fill management gaps

• HSRs being pushed into inappropriate roles

• confusion about accountability following incidents

  
  

What effective practice looks like

In an effective WHS system:

• the PCBU undertakes formal risk management

• officers actively verify compliance and effectiveness

• HSRs inspect, consult and raise issues early

• issues are resolved through consultation wherever possible

• escalation occurs only when necessary

  
  

Each role is understood, respected, and exercised within its legal boundaries.

Key takeaway

The WHS Act does not transfer risk management duties from the PCBU to HSRs — and it never intended to.

HSRs exist to:

• represent workers

• verify that WHS systems work in practice

• challenge unsafe conditions

• escalate unresolved risks

PCBUs and officers remain fully accountable for managing risk. Respecting this separation is essential for lawful compliance, effective consultation, and preventing people from being harmed at work.
