WHS vs OHS: What Victorian Businesses Need to Know

Therefore, OHS should not simply be viewed as an outdated version of WHS. The difference is better understood as a jurisdictional distinction within Australian workplace safety law.

For more information about the broader national framework, businesses can refer to Safe Work Australia's model WHS laws and WorkSafe Victoria's information on the Occupational Health and Safety Act 2004.

Why Does Australia Use Both WHS and OHS?

The use of both terms is largely explained by Australia's approach to harmonising workplace safety legislation.

Australia's move towards harmonised WHS laws

Safe Work Australia developed model WHS laws to support a more nationally consistent approach to workplace health and safety regulation.

The Commonwealth, Australian Capital Territory, New South Wales, Northern Territory and Queensland implemented the model WHS laws on 1 January 2012. South Australia and Tasmania followed on 1 January 2013. Western Australia later implemented a version of the model laws, which became operational on 31 March 2022.

The model framework was intended to improve consistency while allowing individual jurisdictions to implement and administer their own legislation.

It is important to remember, however, that "harmonised" does not mean "identical". Safe Work Australia notes that jurisdictions can make variations to the model laws. Businesses therefore still need to consider the legislation that applies in their particular state or territory.

Why is Victoria different?

Victoria did not implement the model WHS laws.

As a result, Victorian businesses operate under the state's own OHS legislative framework rather than the model WHS Acts used in other jurisdictions. Safe Work Australia currently identifies Victoria as the only Australian jurisdiction that has not implemented the model WHS laws.

This explains why a business owner researching workplace safety online may encounter two different sets of terminology.

A national resource might refer to WHS, while Victorian legislation and WorkSafe Victoria guidance refer to OHS.

For this reason, the statement that "Australia moved from OHS to WHS" is an oversimplification. A more accurate explanation is that most Australian jurisdictions adopted model WHS legislation, while Victoria retained its own OHS framework.

What Does Victoria Use: WHS or OHS?

For Victorian businesses, this is the question that matters most.

Victoria uses an OHS legislative framework. The state's principal workplace health and safety law is the Occupational Health and Safety Act 2004 (Vic), administered by WorkSafe Victoria.

Victoria uses the OHS framework

The Occupational Health and Safety Act 2004 provides the main legal framework for workplace health and safety in Victoria.

The Act establishes duties and rights for people involved in workplaces and sets requirements intended to protect employees and others from risks to health and safety. WorkSafe Victoria describes the Act as the main workplace health and safety law in Victoria.

Victorian businesses may therefore see terms such as:

• occupational health and safety

• OHS duties

• OHS Act

• OHS regulations

• WorkSafe Victoria

• occupational health and safety risks

These terms are consistent with the Victorian legislative framework.

What does the Victorian OHS Act cover?

The OHS Act provides a broad framework for workplace health and safety rather than focusing on a single type of hazard. It establishes general duties for different duty holders and sets out what businesses must do to protect workers’ health and safety.

Key responsibilities under the Victorian OHS framework include:

1. General OHS duties: Part 3 of the Act places general duties on employers, employees, self-employed people and other relevant duty holders.

2. Safe working environment: Employers must provide and maintain a working environment that is safe and without risks to health, so far as is reasonably practicable.

3. Safe systems of work: The Act covers safe plant, systems of work and workplace facilities, along with appropriate information, instruction, training and supervision.

4. Psychological health: Health includes psychological health, meaning duties extend to risks affecting both physical and psychological wellbeing.

Overall, OHS is more than simply a workplace safety label. In Victoria, it operates within a legal framework with specific duties and requirements that businesses need to understand and meet.

Does WHS apply in Victoria?

There is an important distinction here.

Victoria certainly has workplace health and safety obligations, but it has not implemented the model WHS laws. Therefore, businesses should not assume that a model WHS Act or model WHS Regulations automatically apply to a Victorian workplace.

Instead, Victorian businesses should refer to the legislation and regulatory guidance applicable in Victoria.

This distinction becomes especially important for organisations operating in more than one state or territory. A business may use the general term "WHS" when discussing workplace safety nationally while needing to apply the relevant OHS framework to its Victorian operations.

For current Victorian requirements, businesses should check WorkSafe Victoria's OHS legislation and regulations information rather than relying solely on a generic national WHS resource.

WHS vs OHS: Key Differences at a Glance

The easiest way to understand the distinction is to compare the terminology and legislative context side by side.

The table shows why the difference should not be reduced to a simple change in wording.

The underlying objective is closely related, but the applicable legislation depends on where the work is being carried out.

It is also important not to assume that all jurisdictions using WHS have identical rules. Safe Work Australia states that jurisdictions can make variations to the model laws, which is why businesses need to consider the laws applicable in their own state or territory.

Which term should a Victorian business use?

For Victorian workplaces and regulatory matters, OHS is the appropriate legislative terminology. However, businesses may still come across WHS in national resources, industry materials and training content covering multiple Australian jurisdictions.

A practical approach is to consider:

1. Workplace location: Identify where the work is being carried out, as workplace safety requirements can vary between jurisdictions.

2. Applicable legislation: Check which legislation applies to the workplace rather than relying only on the terminology used in a resource.

3. National operations: Organisations operating across Australia may use WHS as a broad organisational term while ensuring their Victorian operations comply with the relevant Victorian OHS requirements.

This approach helps businesses distinguish between general workplace safety language and the specific legal framework that applies in Victoria.

What Does the Difference Mean for Victorian Workplaces?

For most businesses, the practical importance of WHS vs OHS comes down to understanding which legal framework applies, rather than choosing one acronym for branding or internal documents.

The terminology matters because the legislation matters

A generic article about model WHS laws can be useful for understanding Australia's broader approach to workplace safety. However, Victorian businesses should not automatically treat information about the model WHS framework as a complete description of Victorian law.

The jurisdiction determines the applicable legislation, regulator and specific requirements.

This is particularly relevant for businesses that operate across state borders. A national company might have a single workplace safety policy, but its implementation may need to account for differences between jurisdictions.

The safest approach is to understand the common principles while checking the legislation that applies to each location.

The underlying safety principles remain closely related

Although the legal terminology differs, workplace safety still involves practical areas such as:

• identifying risks to workers and others;

• implementing appropriate measures to control risks;

• providing safe systems of work;

• giving workers appropriate information, instruction and training;

• maintaining safe workplaces and work practices;

• considering both physical and psychological health.

In Victoria, the OHS Act requires relevant risks to health and safety to be eliminated or reduced so far as is reasonably practicable. WorkSafe Victoria also confirms that health under the Act includes psychological health.

These principles mean that understanding the terminology is only one part of effective workplace safety. Businesses also need people who understand how safety responsibilities operate in their actual workplace.

What about WHS and OHS training?

Training can help workers and businesses develop a stronger understanding of workplace health and safety responsibilities, terminology and practical safety principles.

For organisations looking to build foundational knowledge, Workplace Health and Safety (WHS) Certified Training can provide a structured introduction to workplace health and safety concepts.

However, training should not be treated as a substitute for understanding the legislation that applies to a particular workplace. Completing a general WHS course does not automatically satisfy every training or competency requirement that may apply to a Victorian role, industry or workplace.

The value of training is strongest when it is combined with workplace-specific procedures, appropriate supervision and an understanding of the relevant regulatory framework.

Conclusion

Understanding WHS vs OHS is less about deciding which acronym is "correct" and more about recognising the Australian jurisdictional framework behind each term.

WHS means Work Health and Safety, while OHS means Occupational Health and Safety. Most Australian jurisdictions have implemented model WHS laws developed by Safe Work Australia, but Victoria has taken a different legislative approach. It remains the only Australian jurisdiction that has not implemented the model WHS laws.

For Victorian businesses, the Occupational Health and Safety Act 2004 remains the main workplace health and safety law, with WorkSafe Victoria responsible for administering Victoria's OHS framework.

The key takeaway is simple: workplace health and safety principles may be closely related across Australia, but businesses must consider the legislation applicable to their jurisdiction. For Victorian workplaces, that means understanding the OHS framework rather than assuming that model WHS legislation applies directly.
