Are Codes of Practice legally binding in Australia?

It depends on the state. In NSW, section 26A of the Work Health and Safety Act 2011 commenced on 1 July 2026 and requires a PCBU to either comply with an approved Code of Practice, or manage the hazards and risks in a different way that provides a standard of health and safety equivalent to or higher than the Code. In the other harmonised states and territories, an approved Code is not a standalone duty but is admissible in proceedings as evidence of whether a duty has been complied with. Victoria uses compliance codes under its own OHS Act instead.

Do I have to follow a Code of Practice exactly?

No. Section 26A allows a different approach, but it has to manage the same hazards and risks to a standard equivalent to or higher than the Code, and you need to be able to demonstrate that if you are asked. The flexibility is real, but the burden of showing your alternative works sits with you.

Does a SWMS template make me compliant with a Code of Practice?

No document can do that on its own. A SWMS is one part of managing the risk, and it has to be reviewed against the actual job, the actual site and the people doing the work before it means anything. What a well-prepared template does is give you a starting point that already names the relevant Codes, legislation and standards, so you are adjusting a document rather than working out from scratch which Code applies.

Q: What changed in NSW on 1 July 2026?

Before 1 July 2026 an approved Code of Practice in NSW was guidance that a court could take into account. From 1 July 2026, section 26A makes it the minimum performance standard a PCBU is expected to meet. Not following an applicable Code, without being able to show an alternative that is equally safe or safer, can be a breach in its own right even if nobody has been hurt.

Q: Are Codes of Practice binding in Victoria?

Victoria is not under the harmonised WHS laws. It runs compliance codes under the Occupational Health and Safety Act 2004 (Vic). Section 152 means that if you follow a compliance code you are taken to have complied with the duty it covers, but not following one does not by itself mean you are in breach. It works as a safe harbour rather than a mandate, which is close to the opposite of the NSW position.

Q: Which Codes of Practice apply to construction work?

The ones that apply depend on the work. Construction work, Managing the risk of falls at workplaces, Excavation work, Demolition work, Confined spaces, Hazardous manual tasks, Managing noise and preventing hearing loss at work, and Managing psychosocial hazards at work are among the most commonly relevant. Each state approves its own version, so check the Code published by your own regulator rather than assuming another state's applies.

It now depends on where you work. In NSW, Codes of Practice became enforceable on 1 July 2026. In the other harmonised states they are still evidence, not a duty, and Victoria runs a different system again. Here's what changed and what it means on site.

What changed in NSW on 1 July 2026?

Section 26A of the Work Health and Safety Act 2011 (NSW) commenced on 1 July 2026. SafeWork NSW describes the effect plainly: approved Codes of Practice are now the minimum performance standards a PCBU is expected to comply with.

That is a change in legal status. Before that date a Code was guidance a court could weigh up after something went wrong. Now, failing to follow an applicable Code, without being able to point to an alternative that is equally safe or safer, can be a breach on its own. Nobody has to be injured first.

What does section 26A actually require?

It gives a duty holder two ways to satisfy it. You either:

Comply with the approved Code of Practice that applies to the work, or
Manage the same hazards and risks in a different way that provides a standard of health and safety equivalent to or higher than the standard required under the Code.

The second option is the important one, and it is widely misread as a loophole. It is not. You keep the flexibility to do things your own way, but the burden of showing that your way meets or beats the Code sits with you, and you need to be able to demonstrate it when asked rather than assert it afterwards.

Are Codes of Practice binding in the other states?

Not in the same way. Outside NSW, the harmonised jurisdictions still run on section 275 of their WHS Act, which makes an approved Code admissible in proceedings as evidence of whether a duty has been complied with. Courts may treat a Code as evidence of what is known about a hazard, a risk or a control, and may rely on it to work out what was reasonably practicable in the circumstances.

In practice that still carries weight. If a regulator or a court is deciding whether you did what was reasonably practicable, the Code is the yardstick they reach for. The difference is that in NSW it is now the duty itself, and elsewhere it is the evidence used to judge the duty.

Where each state sits:

NSW: section 26A. Comply with the Code, or meet an equivalent or higher standard another way. In force since 1 July 2026.
QLD, SA, WA, TAS, NT, ACT: section 275. Codes are admissible as evidence of whether a duty was met, and are used to establish what is reasonably practicable.
VIC: not under the harmonised WHS laws at all. Compliance codes under the Occupational Health and Safety Act 2004 (Vic).

Why does Victoria work differently?

Victoria never adopted the model WHS laws, which is why its documents cite a different Act and a different regulator. Instead of approved Codes of Practice it has compliance codes, and section 152 of the OHS Act 2004 gives them a different legal effect.

If you follow a Victorian compliance code, you are taken to have complied with the duty it covers. If you do not follow it, that alone does not put you in breach, provided you have met the duty some other way. So a Victorian compliance code operates as a safe harbour you can choose to use, which is close to the reverse of what NSW now does. Our state-by-state guide covers the wider differences.

Which Codes of Practice apply to construction work?

It depends on the job, and more than one usually applies at once. The ones that come up most often on a construction site are Construction work, Managing the risk of falls at workplaces, Excavation work, Demolition work, Confined spaces, Hazardous manual tasks, Managing noise and preventing hearing loss at work, and Managing psychosocial hazards at work.

Each state approves its own version of these, and they are not always identical. A Code published by SafeWork NSW is not the Code that applies to a job in Perth. If you work across borders, the applicable Code changes with the site, which is the same reason a SWMS needs to be written for the state the work is in.

What does this mean for your SWMS?

A SWMS is not a Code of Practice and does not replace one. What the NSW change does is raise the cost of a vague document. If a Code sets out how a hazard should be controlled and your SWMS quietly does something less, that gap is now a compliance question in NSW rather than a matter of opinion.

Three things are worth checking in any SWMS you are relying on:

Does it name the Codes it relies on? A document that references safety in general terms gives you nothing to point at when someone asks which standard you were working to.
Are they the right state's Codes? Citing the wrong regulator is a common fault in generic templates, and it is obvious to anyone reviewing the document.
Do the controls actually match? If you have chosen a different control from the one the Code describes, you should be able to explain why yours is equivalent or better.

Every SWMS we sell lists the Codes it relies on by name, under the regulator for that state and Safe Work Australia, alongside that state's Act and Regulations and the relevant Australian Standards. The Victorian versions say so in Victorian terms: compliance codes, the Occupational Health and Safety Act 2004 (Vic), and a note that Victoria is not under the harmonised WHS laws. That gives you a starting point to review rather than a blank page. It does not make you compliant on its own, and no template can: the document still has to be adjusted for the job, the site and the crew, and signed on before work starts.

What should you do now?

Work out which Codes apply to the work you do. Start with your own regulator's list, not a generic one, and expect several to apply at once.
Read them against your current documents. You are looking for places where the Code describes a control and your paperwork is silent or weaker.
Where you differ from a Code, write down why. If you are relying on the equivalent-or-higher path in NSW, the reasoning needs to exist somewhere before you are asked for it.
Check your documents name the right state. This is the fastest thing to fix and the most commonly wrong.
