WHS Legislation

About this topic

WHS legislation is the legal backbone of construction safety in Australia, and it is one of the most heavily tested areas on the White Card (CPCWHS1001) assessment. You do not need to memorise the law word-for-word, but you do need to understand who is responsible for safety, what your own duties are, and what rights you have as a worker. This page explains the essentials in plain English, then lets you practise with real exam-style questions.

What "WHS law" actually is

Most of Australia follows the model Work Health and Safety (WHS) Act 2011. It has been adopted by the Commonwealth, New South Wales, Queensland, South Australia, Tasmania, the ACT and the Northern Territory. Western Australia joined them through its own WHS Act 2020, which commenced on 31 March 2022. Victoria is the one exception: it never adopted the model laws and instead uses its Occupational Health and Safety (OHS) Act 2004.

The good news for your White Card: the core safety principles are essentially the same everywhere. Whether your site is governed by the WHS Act or Victoria's OHS Act, the duties, the focus on managing risk "so far as is reasonably practicable", and your right to a safe workplace all carry across.

Who has WHS duties? (the duty holders)

The law spreads responsibility across several roles. Understanding who does what is the key to most legislation questions:

• The PCBU (Person Conducting a Business or Undertaking) holds the primary duty of care. This is usually the company or employer. It must ensure, so far as is reasonably practicable, the health and safety of workers and anyone else affected by the work — including providing safe systems, training, equipment and supervision.
• Officers (such as company directors) must exercise due diligence — actively making sure the business meets its WHS duties. Due diligence is proactive, not a matter of waiting for something to go wrong.
• Workers (including employees, contractors, apprentices and labour-hire staff) must take reasonable care for their own safety, take reasonable care not to harm others, follow reasonable safety instructions, and comply with site policies and procedures.
• Others at the workplace (such as visitors) must take reasonable care for themselves and others and follow reasonable instructions.

Your rights as a worker

WHS law does not just impose duties — it gives you real protections:

• The right to a safe workplace and to be consulted about health and safety matters that affect you.
• The right to cease or refuse unsafe work if you have a reasonable concern that it would expose you to a serious risk from an immediate or imminent hazard.
• The right to elect a Health and Safety Representative (HSR) to represent your work group.
• Protection from discrimination for raising a safety concern or exercising a WHS right.

Penalties — and why they matter to you

WHS breaches are taken seriously. The model law sets out tiered offences, with Category 1 (reckless conduct that exposes a person to a risk of death or serious injury) carrying the heaviest penalties — originally up to around $3 million for a body corporate, with several states now setting higher maximums. Most jurisdictions have also introduced industrial manslaughter offences carrying very large fines and potential imprisonment. You will not be asked the exact dollar figures on the White Card, but you should understand that both businesses and individuals can be held legally accountable for unsafe behaviour.

What the White Card test asks about legislation

Legislation questions on the assessment tend to focus on understanding rather than memorising. Expect questions like: who is mainly responsible for safety on site (the PCBU); what your duties are as a worker; what to do if you see or are asked to do something unsafe; and who you can raise a concern with. If you understand the roles above, you will handle these comfortably.

Key facts to remember

• The PCBU has the primary duty of care, not the individual worker.
• Workers must take reasonable care for their own and others' safety and follow reasonable instructions.
• Officers must exercise due diligence — being proactive, not reactive.
• Category 1 offences (reckless conduct) carry the highest penalties; industrial manslaughter laws now apply in most states.
• Workers have the right to cease unsafe work and to elect an HSR.
• The model WHS Act applies everywhere except Victoria, which uses its OHS Act 2004.

Frequently asked questions

What law covers White Card safety in Australia?
Most states and territories follow the model WHS Act 2011; Western Australia uses its WHS Act 2020 (from 2022) and Victoria uses the OHS Act 2004. The safety principles you learn for the White Card apply under all of them.

Who has the main responsibility for safety on a worksite?
The PCBU — the business or employer — holds the primary duty of care. Workers have their own duties too, but the main responsibility sits with the PCBU.

What are a worker's WHS duties?
Take reasonable care for your own safety, take reasonable care not to harm others, follow reasonable safety instructions, and comply with the site's safety policies and procedures.

Can I refuse unsafe work?
Yes. You can cease or refuse work if you have a reasonable concern it would expose you to a serious risk from an immediate or imminent hazard. Tell your supervisor and stay available for other safe work.
