Workplaces can look very different, from offices and retail stores to construction sites, warehouses and home-based work. What they have in common is the need to manage anything that could harm people while work is being carried out.
So, what is WHS? WHS stands for Work Health and Safety. In Australia, it refers to the laws, duties and workplace systems designed to protect people's health and safety in connection with work. This includes both physical and psychological health.
Understanding WHS starts with a few straightforward ideas: recognise what could cause harm, manage the risks, understand who has responsibilities and make safe work part of everyday operations.
What Does WHS Stand For?
WHS stands for Work Health and Safety. You may also see the phrase "workplace health and safety" used informally, but Work Health and Safety is the terminology used in Australia's model WHS framework.
The Australian Government describes work health and safety as the laws and systems that help prevent workplace harm and injury. WHS is broader than simply responding when someone gets hurt. It includes creating and maintaining working conditions that reduce the risk of harm in the first place.
That can involve:
-
maintaining a safe work environment;
-
identifying and managing workplace hazards and risks;
-
providing appropriate information, instruction, training and supervision;
-
using safe systems of work; and
-
protecting physical and psychological health.
WHS can also extend beyond employees. Depending on the applicable duties and circumstances, workers, contractors, visitors, customers and others affected by work activities may need to be considered.
What Is the Purpose of WHS?
The central purpose of WHS is to protect people from work-related harm.
Rather than waiting for an incident to happen, effective WHS focuses on identifying potential sources of harm and taking appropriate steps to eliminate risks or, where elimination is not reasonably practicable, minimise them.
In practice, this means thinking about questions such as:
-
What could cause harm here?
-
Who could be affected?
-
What risks arise from the hazard?
-
What can be done to eliminate or minimise those risks?
-
Are the controls still working as intended?
This preventative approach applies to more than obvious physical dangers. Australian WHS guidance recognises both physical and psychological health, so safe work involves considering how work is designed, managed and carried out.
For a business, WHS therefore is not simply a policy stored in a folder. It should form part of how work is planned, communicated and performed.
What Does WHS Cover in the Workplace?
WHS can apply to many aspects of work, from equipment and physical working conditions to work design and workplace behaviour. Two concepts are particularly important for beginners: hazards and risks.
Workplace Hazards and Risks
A hazard is something or a situation that has the potential to cause harm. A risk considers the likelihood of that harm occurring and how serious the consequences could be.
Australian Government guidance makes this distinction when explaining workplace risk management.
A simple example shows how the concepts connect:
|
WHS concept |
Simple workplace example |
|
Hazard |
A wet floor in a busy walkway |
|
Risk |
A worker or visitor could slip and be injured |
|
Control |
Clean the spill and prevent access until the area is safe |
Workplace hazards vary according to the type of work. They may involve machinery, hazardous chemicals, manual tasks, noise, working conditions, slips and falls or workplace interactions and behaviours.
The right approach depends on the actual workplace and the risks involved, which is why WHS should not be reduced to a generic checklist.
Physical and Psychological Health
Work health and safety is not limited to preventing physical injuries.
Under the model WHS framework, health includes physical and psychological health. Safe Work Australia explains that psychosocial hazards can arise from matters such as job demands, low job control, poor support, remote or isolated work, traumatic events, violence, bullying, harassment and workplace conflict.
The specific risks and appropriate controls vary between workplaces. The important point for a beginner is that WHS considers how work may affect the whole health of a worker, not just the risk of an obvious physical accident.
Who Is Responsible for WHS?
WHS is often described as a shared responsibility, but that does not mean everyone has identical legal duties. The model WHS laws establish different duties for PCBUs, officers, workers and other people at a workplace.
PCBUs and Businesses
A key term in Australian WHS law is person conducting a business or undertaking, usually shortened to PCBU.
A PCBU is a broader concept than simply an "employer". Under the model WHS laws, a PCBU has a primary duty to ensure, so far as is reasonably practicable, the health and safety of workers while they are at work in the business or undertaking. The duty also extends to other people who may be affected by the work.
Depending on the circumstances, this includes matters such as safe work environments, safe systems of work, safe plant and structures, facilities and appropriate information, training, instruction and supervision.
Officers
Officers have their own WHS responsibilities. Under the model framework, an officer must exercise due diligence to ensure the PCBU complies with its WHS duties.
Who qualifies as an officer depends on the organisation and the person's role. It should not be assumed that every manager automatically falls within the legal definition.
Workers
Workers have duties too. They must take reasonable care of their own health and safety and that of others who may be affected by what they do or fail to do. They must also comply, so far as reasonably able, with reasonable WHS instructions and cooperate with notified workplace health and safety policies and procedures.
Importantly, "worker" can be broader than "employee". Under the model laws it can include contractors, subcontractors, apprentices, trainees, work experience students, labour hire workers and volunteers in relevant circumstances.
How Do WHS Laws Work in Australia?
Australia does not have one WHS Act that automatically applies identically to every workplace nationwide.
Safe Work Australia develops and evaluates the model WHS laws, which include:
-
the model WHS Act;
-
the model WHS Regulations; and
-
model Codes of Practice.
These model laws provide a framework for jurisdictions to implement. They do not automatically become law in a state or territory simply because the model framework changes. The Commonwealth, states and territories are responsible for implementing, regulating and enforcing the WHS laws that apply within their jurisdictions.
Most Australian jurisdictions have implemented model-based WHS laws, although there can be jurisdictional variations. Victoria is the exception and continues to operate under its occupational health and safety framework.
For a broader explanation of legislation, regulators and workplace requirements across Australia, ACT's Work Health and Safety (WHS) in Australia: 2026 Guide provides the more appropriate in-depth coverage.
Businesses should ultimately check the legislation and regulator guidance that applies in their own jurisdiction rather than relying solely on the model laws.
What Is the Difference Between WHS and OHS?
WHS means Work Health and Safety, while OHS means Occupational Health and Safety. The terms refer to closely related concepts and are sometimes used interchangeably in everyday workplace discussions.
The important distinction in Australia is jurisdictional.
Most jurisdictions have adopted legislation based on the model WHS laws and use WHS terminology. Victoria has not implemented the model WHS laws and continues to operate under its OHS legislation. Safe Work Australia's overview of WHS legislation explains the current jurisdictional position.
It is therefore inaccurate to say that WHS simply replaced OHS everywhere in Australia.
For businesses, the practical priority is to understand the terminology, legislation and regulator requirements that apply in the jurisdiction where the work is being performed.
What Does WHS Look Like in Everyday Work?
WHS becomes easier to understand when it is viewed as an ongoing process rather than a document or annual compliance exercise.
A simple workplace sequence might look like this:
Hazard identified → risk considered → control introduced → workers informed or trained → control monitored and reviewed
For example, an organisation might identify unsafe equipment, take it out of service, arrange appropriate repairs and make sure workers know not to use it until it is safe.
In another workplace, WHS might involve consulting workers about high job demands or poor support that could create psychosocial risks. In an office, something as ordinary as keeping walkways clear, maintaining equipment and providing safe work procedures can form part of everyday health and safety.
The exact measures required depend on the work, hazards and applicable duties. What matters is that WHS becomes part of normal decision-making, rather than something considered only after an incident occurs.
Why WHS Training Matters
Policies and procedures are more useful when people understand what they mean and how they apply to their work.
Training can help workers recognise hazards, understand workplace safety procedures, know their responsibilities and respond appropriately when they identify a concern. Under the model WHS framework, PCBUs' primary duty includes providing necessary information, training, instruction and supervision to protect people from risks arising from work.
The type and level of training required should reflect the workplace, role, hazards and applicable legal requirements. Completing one general course does not, by itself, satisfy every WHS obligation or replace workplace-specific instruction and supervision.
For organisations looking to build foundational awareness, ACT's Workplace Health and Safety (WHS) Certified Training can support broader workplace WHS education alongside appropriate policies, procedures, supervision and role-specific training.
Understanding WHS Is the Starting Point
WHS means more than preventing visible workplace accidents. It is about protecting physical and psychological health by identifying hazards, managing risks, understanding responsibilities, consulting where required and maintaining appropriate systems for safe work.
For someone new to workplace compliance, understanding what WHS is provides the foundation. From there, businesses and workers can look more closely at the legislation, risks and requirements that apply to their particular workplace and jurisdiction.
Good WHS starts with understanding the work being done, the people who may be affected and what can reasonably be done to keep that work safe.
