Duty of Care in WHS for Australian Businesses

If you run a small business in Australia, workplace health and safety (WHS) probably sits somewhere between “important” and “I’ll deal with it when I have time”. But WHS isn’t just paperwork - it’s a core legal obligation, and it directly affects your people, your customers, and your ability to keep trading.

One of the most searched (and most misunderstood) topics is duty of care in WHS. In simple terms, your business has a legal responsibility to take reasonable steps to keep people safe while work is being done.

The good news is that you don’t need to be a WHS expert to get this right. You just need a clear understanding of what the duty means, who owes it, and what “reasonable steps” look like in a small business environment.

Below, we’ll walk you through duty of care in WHS from a small business owner’s perspective, including practical examples and the key actions to take to reduce risk. This article is general information only and isn’t legal advice - because WHS obligations can vary depending on your state or territory, your industry, and how your business operates.

What Does “Duty Of Care In WHS” Actually Mean?

In a WHS context, “duty of care” is the legal obligation to ensure health and safety so far as is reasonably practicable in relation to work.

In most Australian states and territories, WHS laws are based on a harmonised model (often called the model WHS laws). However, not every jurisdiction uses the model framework in the same way - for example, Victoria operates under its own Occupational Health and Safety (OHS) laws. Even where the legislation differs, the general principle is consistent: if you run a business, you must actively manage workplace safety risks.

For small businesses, this can include your obligation to:

• provide and maintain a safe work environment
• ensure safe systems of work (how the work is done day-to-day)
• provide information, training, instruction and supervision
• ensure plant and equipment are safe (tools, machinery, vehicles)
• manage risks around hazardous substances and manual handling
• monitor worker health and workplace conditions where relevant

Importantly, WHS isn’t only about avoiding accidents. It can also include psychological health (for example, risks relating to bullying, fatigue, and high job demands) where those risks are connected to work.

What Does “So Far As Is Reasonably Practicable” Mean?

This phrase comes up constantly in WHS. It generally means you’re expected to do what is reasonable in the circumstances - not what is perfect, and not what is impossible.

What’s “reasonably practicable” is usually assessed by looking at factors like:

• how likely the hazard or risk is to occur
• how serious the harm could be
• what you know (or should know) about the hazard and how to control it
• what control measures are available and suitable
• the cost of controls (but cost alone won’t justify doing nothing if the risk is significant)

For example, a small retail shop may not need the same controls as a construction site - but both businesses still need to identify and manage the hazards that actually exist in their workplace.

Who Owes A Duty Of Care Under WHS Laws?

In jurisdictions that follow the model WHS laws, the primary duty of care is typically placed on the person conducting a business or undertaking (PCBU). In everyday terms, that’s usually your business entity - the company, sole trader, partnership, or trust operating the business.

However, because WHS and OHS laws aren’t identical across Australia, the terminology and exact obligations can differ between states and territories. Even so, in practice, safety duties often apply to multiple people at once. Depending on your setup, this can include:

• Your business (often called the PCBU in model WHS jurisdictions): holds the main duty to ensure health and safety so far as reasonably practicable.
• Officers: people who make (or participate in making) high-level decisions, such as directors. They may have their own obligation to exercise “due diligence” (or an equivalent standard) to ensure the business complies.
• Workers: including employees, contractors, labour hire workers, apprentices, and sometimes volunteers. Workers also have duties to take reasonable care for their own safety and follow reasonable instructions.
• Other people at the workplace: like customers, visitors, and delivery drivers - you may owe duties to ensure they aren’t exposed to risks arising from your work.

This is why WHS can’t be treated as “HR’s job” or “the site supervisor’s job”. WHS is a business-wide responsibility, and your systems need to work even when you’re busy, understaffed, or growing quickly.

If I Use Contractors, Do I Still Have WHS Duties?

Yes - and this is a common trap for small businesses.

Even if someone is a contractor (not an employee), your business may still have WHS duties to ensure the work is carried out safely, especially if the work is performed at your site, using your equipment, or under your direction.

This is one reason why it’s important to be clear about your engagement terms and expectations. If you’re hiring staff, having an Employment Contract in place helps set clear responsibilities and processes (including around workplace conduct and safety expectations) from day one.

What Does Duty Of Care Look Like In Practice For Small Businesses?

Duty of care in WHS isn’t just a statement - it’s a set of ongoing actions. For small businesses, the key is building simple, repeatable systems that actually work in the real world.

Below are the practical areas we typically recommend small business owners focus on first.

1. Identify Hazards (Before They Turn Into Incidents)

A hazard is anything with the potential to cause harm. In a small business, hazards can be obvious (like a slippery floor) or less obvious (like repetitive tasks causing strain injuries).

Examples of hazards by industry might include:

• Retail/hospitality: wet floors, poor lighting, cash handling risks, aggressive customers, fatigue from shift work
• Trades/construction: working at heights, electrical hazards, manual handling, machinery and power tools
• Office-based businesses: workstation ergonomics, psychosocial risks, stress and burnout, poor ventilation
• Health/beauty: chemical exposure, sharps, infection control, manual handling, harassment risks

Hazard identification should be regular - not a once-a-year formality.

2. Assess The Risks And Put Controls In Place

Once you’ve identified hazards, you need to assess how serious they are and implement control measures.

Control measures can include:

• changing the task or work process to remove the hazard
• substituting safer materials (e.g. replacing a harsh chemical with a safer one)
• using physical safeguards (guards, barriers, anti-slip mats)
• introducing safe work procedures and checklists
• providing personal protective equipment (PPE) where needed
• training and supervision

If you ever find yourself thinking “we’ve always done it this way”, it’s worth pausing. Past luck isn’t the same as compliance.

3. Train People Properly (And Document It)

Training is one of the most practical ways to meet your WHS duty of care - and it’s often overlooked in small teams where everyone is “meant to already know” how things work.

For example, training might cover:

• how to operate equipment safely
• how to handle hazardous substances
• what to do in emergencies
• incident reporting processes
• customer aggression and de-escalation (where relevant)

It’s also important to keep basic records: who was trained, on what, and when. If there’s ever an incident, those records can be crucial.

4. Maintain A Safe Workplace (Not Just A “Safe Job Description”)

Your WHS duties cover the workplace environment too - things like lighting, cleanliness, ventilation, access/egress, and the condition of equipment.

Small examples that matter:

• fixing a damaged step instead of “being careful around it”
• making sure fire exits aren’t blocked (even during stock deliveries)
• repairing frayed power cords rather than taping them up
• ensuring first aid supplies are stocked and easy to access

WHS compliance is often the accumulation of small, consistent safety decisions.

Managing WHS Risks When You Hire, Roster, Or Change Work Hours

For many small businesses, WHS risk isn’t limited to physical hazards. The way you schedule work, respond to absences, and manage workloads can create WHS risks too - especially psychosocial risks like fatigue, stress, and burnout.

This comes up a lot in industries like hospitality, retail, healthcare, and logistics.

Fatigue, Shift Changes, And Unsafe Work Practices

If your workers are routinely fatigued, you can end up with higher incident rates, lower concentration, and increased conflict - all of which may create WHS exposure.

Having clear, lawful processes around rostering and changes helps reduce confusion and last-minute scrambling. For example, it can be useful to understand the minimum notice for shift changes and how it interacts with awards and contracts.

Workplace Policies Make WHS Easier To Enforce

Many WHS problems become harder when expectations aren’t documented. Even a straightforward workplace policy framework can help you consistently enforce safety and behaviour standards.

Depending on your workplace, you might need policies dealing with things like device use, recording, surveillance, and privacy. If your team uses phones on the job (whether for customer service, deliveries, or admin), a clear mobile phone policy can help manage distraction-related risks and confidentiality issues.

What Happens If You Breach Your Duty Of Care In WHS?

WHS breaches can have serious consequences - and not only after a major accident.

Depending on what happens and how your regulator responds, consequences can include:

• improvement or prohibition notices (requiring you to fix issues or stop work)
• enforceable undertakings (formal agreements with the regulator)
• significant fines
• court proceedings
• reputational damage (including staff retention and customer trust)

In serious cases, WHS laws can also involve personal liability for officers (like directors) if they didn’t exercise due diligence.

From a business perspective, WHS incidents also have hidden costs: downtime, workers compensation claims, hiring and retraining, increased insurance premiums, and the management time needed to respond to regulators and investigations.

That’s why it’s worth treating WHS as a core part of running your business - just like invoicing, customer service, and cash flow management.

Do I Need Written WHS Documents?

Often, yes - but exactly what you need depends on your business activities, industry, and risk profile.

As a starting point, many businesses consider having:

• a WHS policy and procedures (including incident reporting and risk management)
• training records and induction checklists
• safe work method statements (SWMS) if you do high-risk construction work
• contracts and workplace documents that support compliance

If you’re unsure what documents you need, it can help to get advice that’s tailored to your state or territory and your specific work activities.

Key Legal Documents That Support Your WHS Duty Of Care

WHS isn’t just about signs on walls and safety checklists - it’s also about having clear legal frameworks that set expectations and reduce misunderstandings (especially as you hire, scale, or work with third parties).

Depending on your business model, you may want to consider:

• Employment Contract: sets out duties, performance expectations, and workplace rules, supporting consistent safety management across your team.
• Workplace Policies: helps you clearly communicate safety processes, behavioural standards, and reporting pathways (especially important when managing incidents or misconduct).
• Contractor Agreement: clarifies scope, responsibilities, and WHS coordination when you engage contractors (particularly if they attend your workplace or represent your business).

Not every small business needs every document on day one, but putting the right ones in place early usually makes WHS compliance (and general risk management) much easier.

Key Takeaways

• Duty of care in WHS is your legal responsibility to take reasonable steps to keep people safe while work is carried out, including physical and psychological risks.
• WHS duties commonly apply to your business (often as the PCBU in model WHS jurisdictions), officers (like directors), and workers - and the duties can overlap.
• Meeting your WHS duty of care usually comes down to practical systems: identifying hazards, controlling risks, training staff, and maintaining a safe workplace.
• Rostering, shift changes, fatigue and workplace behaviour can all create WHS risks, so it’s worth having clear processes and policies.
• Breaching WHS duties can lead to notices, fines, legal action, business disruption, and reputational damage.
• Having clear contracts and workplace documents in place (like employment contracts, contractor agreements, and workplace policies) can support WHS compliance and reduce misunderstandings as your business grows.
