When Can Company Directors Be Personally Liable Under WHS Laws?

Work health and safety (WHS) legislation imposes significant obligations on organisations to ensure the health and safety of workers and others affected by their operations. While these duties are often associated with companies as the primary duty holders, WHS laws also impose personal obligations on individuals who occupy leadership roles within organisations.

Directors and senior executives can be personally liable under WHS legislation where they fail to exercise due diligence to ensure their organisation complies with its safety obligations. This reflects the legislative intention that workplace safety must be actively overseen at the highest levels of organisational leadership.

Understanding when personal liability may arise is therefore an important issue for company directors and senior managers involved in industries with higher workplace risk, including construction.

The Due Diligence Duty

Under WHS legislation, company officers have a duty to exercise due diligence to ensure that the organisation complies with its obligations under the law.

An officer generally includes individuals who make or participate in decisions that affect the whole or a substantial part of the business. This commonly includes:

• company directors
• chief executive officers
• senior executives
• other individuals with significant decision-making authority

Importantly, this duty applies personally to officers. It cannot be delegated to safety managers or operational staff.

The due diligence obligation requires officers to take reasonable steps to ensure their organisation has appropriate systems in place to manage workplace health and safety risks.

Why Directors Are Increasingly Being Scrutinised

Regulators are increasingly focusing on the role of organisational leadership when serious workplace incidents occur.

Investigations following major incidents often examine not only what occurred on site, but also how safety risks were overseen at a governance level. This may include examining whether directors received adequate information about safety risks, whether appropriate resources were allocated to risk management and whether systems were in place to verify that safety controls were operating effectively.

As a result, directors and senior executives are increasingly expected to demonstrate active oversight of workplace health and safety within their organisations.

What Does Due Diligence Require?

While the exact actions required will depend on the nature of the organisation and the risks involved, WHS legislation outlines several key elements of due diligence.

These include taking reasonable steps to:

• acquire and maintain up-to-date knowledge of WHS matters
• understand the operations of the organisation and the hazards associated with those operations
• ensure the organisation has appropriate resources and processes to eliminate or minimise risks
• ensure there are processes for receiving and responding to information about incidents, hazards and risks
• ensure the organisation has processes for complying with WHS obligations
• verify that these systems and processes are actually implemented and functioning effectively

The final element — verification — is often the most challenging in practice.

It is not enough for officers to assume that safety systems exist or that policies are being followed. Officers must take reasonable steps to confirm that those systems are operating effectively within the organisation.

When Can Personal Liability Arise?

Personal liability may arise where an officer fails to exercise due diligence and the organisation breaches its WHS obligations.

This may occur where officers:

• fail to ensure appropriate safety systems are implemented
• do not allocate adequate resources to manage workplace risks
• ignore information about developing safety issues
• fail to monitor whether safety procedures are being followed
• do not take reasonable steps to verify the effectiveness of safety systems

Regulators may examine whether officers took reasonable steps to understand and monitor safety risks within the organisation, particularly where serious incidents result in injury or fatality.

Where such failures occur, regulators may pursue enforcement action against the organisation and, in some circumstances, the officers involved.

Penalties for officers can be significant and may include substantial fines and, in the most serious cases, imprisonment.

The Verification Challenge

In many organisations, safety systems appear comprehensive on paper. Policies, procedures and training frameworks may all exist within the organisation.

However, incidents and prosecutions often reveal that the real issue is not the absence of safety systems, but the failure to verify how those systems operate in practice.

Construction projects often involve multiple contractors, evolving work environments and rapidly changing hazards. As a result, safety systems that appear robust at a governance level may not always operate as intended on site.

Without effective oversight and verification, safety systems can gradually weaken over time.

Identifying Risks Before Incidents Occur

Regulatory investigations following serious incidents frequently identify hazards that had been present on site well before the event occurred.

For directors and senior leaders, maintaining visibility over how safety risks are developing across projects is therefore critical.

Independent WHS Assurance Reviews can assist organisations by providing objective insight into how safety risks are developing on site, helping leadership teams identify emerging issues and assess whether existing safety controls remain effective.

Leadership Insight

Questions Directors Should Be Asking

For many directors, the key issue is not whether safety systems exist within the organisation, but whether those systems are functioning effectively in practice.

Some questions directors and senior leaders may wish to consider include:

• Do we have clear visibility over how safety risks are developing across our projects?
• How do we verify that safety procedures are actually being followed on site?
• Are emerging hazards identified early enough to prevent incidents?
• Do we receive reliable information about developing safety risks?
• Are our safety systems being independently reviewed or verified?

Addressing these questions can help directors strengthen their oversight of workplace health and safety and reduce potential exposure to regulatory enforcement.

Frequently Asked Questions About Director Liability Under WHS Laws

Can directors be personally prosecuted under WHS laws?

Yes. WHS legislation allows regulators to prosecute company officers where they fail to exercise due diligence to ensure the organisation complies with its safety obligations.

Can directors be liable even if they were not directly involved in the incident?

Yes. The due diligence duty focuses on leadership oversight and governance. Directors may face liability where they fail to ensure that appropriate systems and processes exist to manage workplace risks.

What is the most important part of the due diligence duty?

One of the most challenging elements is verifying that safety systems are actually implemented and functioning effectively in practice. This requires more than simply approving policies or procedures.

How can directors demonstrate due diligence?

Directors may demonstrate due diligence by actively engaging with WHS issues, ensuring appropriate safety systems are in place, monitoring safety performance and taking reasonable steps to verify that risk controls are functioning effectively.
