WHS Guides & Resources

Plain-English answers on SWMS, JSA and WHS compliance — written for Australian tradies, referenced to the actual legislation.

SWMS Basics

What Is a SWMS? Safe Work Method Statements Explained

A Safe Work Method Statement (SWMS) is a written document the WHS Regulations require before any high risk construction work starts. It must identify the high risk work, spell out the hazards, describe the control measures, and explain how those controls will be implemented, monitored and reviewed. This guide covers what a SWMS is, who prepares it, and when the law demands one.

SWMS vs JSA: What's the Difference and Which Do You Need?

A SWMS is a legally mandated document required before any of the 18 high risk construction work activities listed in s.291 of the WHS Regulations, with content prescribed by s.299. A JSA is a general risk-assessment tool with no prescribed format, used for everyday task planning. A JSA cannot stand in for a SWMS where the law demands one.

High Risk Construction Work: The Full List of 18 HRCW Activities

High risk construction work (HRCW) is defined in s.291 of the model WHS Regulations, which lists 18 activities from working above 2 metres to diving work. If your job involves even one of them, you must prepare a Safe Work Method Statement before work starts. This guide reproduces the full 18-activity list and explains what each trigger means on site.

SWMS Legal Requirements: Sections 299 to 303 Explained

Five sections of the model WHS Regulations set the legal requirements for a SWMS: s.299 (what it must contain), s.300 (work must comply or stop), s.301 (copy to the principal contractor), s.302 (review) and s.303 (record keeping). This guide explains each duty, the on-the-spot fines, how long you must keep a SWMS, and how to check yours is compliant.

JSA by State

JSA Requirements in New South Wales

No NSW law requires a document called a Job Safety Analysis. What the law requires is the risk management process behind it, and what principal contractors require is evidence you followed it. This guide covers the duties a JSA answers to in New South Wales, the line where a SWMS becomes mandatory instead under s.299, and what belongs in a NSW JSA.

JSA Requirements in Victoria

No VIC law requires a document called a Job Safety Analysis. What the law requires is the risk management process behind it, and what principal contractors require is evidence you followed it. This guide covers the duties a JSA answers to in Victoria, the line where a SWMS becomes mandatory instead under Reg 327, and what belongs in a VIC JSA.

JSA Requirements in Queensland

This guide covers the duties a JSA answers to in South Australia, the line where a SWMS becomes mandatory instead under s.299, and what belongs in a SA JSA.

JSA Requirements in Tasmania

No TAS law requires a document called a Job Safety Analysis. What the law requires is the risk management process behind it, and what principal contractors require is evidence you followed it. This guide covers the duties a JSA answers to in Tasmania, the line where a SWMS becomes mandatory instead under s.299, and what belongs in a TAS JSA.

JSA Requirements in Australian Capital Territory

No ACT law requires a document called a Job Safety Analysis. What the law requires is the risk management process behind it, and what principal contractors require is evidence you followed it. This guide covers the duties a JSA answers to in Australian Capital Territory, the line where a SWMS becomes mandatory instead under s.299, and what belongs in a ACT JSA.

This guide covers the duties a JSA answers to in Northern Territory, the line where a SWMS becomes mandatory instead under Reg 299, and what belongs in a NT JSA.

SWMS by State

SWMS Requirements in NSW: What the Law Says

NSW follows the harmonised national WHS scheme. The Work Health and Safety Act 2011 (NSW) and the Work Health and Safety Regulation 2017 (NSW) require a safe work method statement before any of the 18 high risk construction work activities in s.291 can start. This guide covers when a SWMS is required in NSW, what it must contain under s.299, and how SafeWork NSW enforces the rules.

SWMS Requirements in Victoria: OHS Act 2004 and Regulation 327

Victoria never joined the national WHS scheme, so SWMS requirements come from the Occupational Health and Safety Regulations 2017 (Vic), not the model WHS Regulations. Regulation 327 requires employers to prepare a SWMS before high risk construction work starts, and Regulation 322 defines 19 classes of that work. This guide covers who must prepare one, what it must contain, and how WorkSafe Victoria enforces it.

SWMS Requirements in Queensland

Queensland applies the national model WHS laws through the Work Health and Safety Act 2011 (Qld) and WHS Regulation 2011 (Qld). If your crew carries out any of the 18 high risk construction work activities in s.291, the PCBU must prepare a SWMS under s.299 before work starts. Here is what the law requires, what the document must contain, and how Queensland compares with other states.

SWMS Requirements in Western Australia

Western Australia now runs on the harmonised WHS scheme through the WHS Act 2020 (WA) and the WHS (General) Regulations 2022 (WA). A SWMS is mandatory before any high risk construction work as defined in Reg 291, with the requirement to prepare one and its content rules set by Reg 299, and is enforced by WorkSafe WA. Here is what WA tradies and subcontractors need to know.

SWMS Requirements in South Australia

South Australia runs the harmonised WHS scheme: the WHS Act 2012 (SA) and WHS Regulations 2012 (SA), enforced by SafeWork SA. A SWMS is mandatory before any high risk construction work under regulation 299, with the 18 triggering activities defined in regulation 291. Since 1 July 2026, SA's fall-from-height trigger dropped from 3 metres to 2 metres, so jobs that never needed a SWMS in SA now do.

SWMS Requirements in Tasmania

Tasmania runs the harmonised WHS scheme: the Work Health and Safety Act 2012 (Tas) and the Work Health and Safety Regulations 2022 (Tas), enforced by WorkSafe Tasmania. A SWMS is mandatory before any high risk construction work under s.299, with the 18 triggering activities defined in s.291. The 2022 regulations replaced the 2012 set and kept the same provision numbers, so a SWMS that still cites the 2012 regulations needs its references updated.

SWMS Requirements in the ACT

The ACT runs the harmonised WHS scheme: the Work Health and Safety Act 2011 (ACT) and the Work Health and Safety Regulation 2011 (ACT), enforced by WorkSafe ACT. A SWMS is mandatory before any high risk construction work under s.299, with the 18 triggering activities defined in s.291. On the government and commercial projects common in the ACT, the principal contractor obtains your SWMS under s.301 and it is often read before you start.

SWMS Requirements in the Northern Territory

The Northern Territory runs the national model WHS laws under the Work Health and Safety (National Uniform Legislation) Act 2011 (NT) and its Regulations, enforced by NT WorkSafe. A SWMS is mandatory before any high risk construction work under Reg 299, with the 18 triggering activities defined in Reg 291. Outdoor heat does not itself trigger a SWMS, but on NT jobs it belongs in the SWMS for outdoor work as a site condition.

Do I Need a SWMS For…

Do I Need a SWMS for Working at Heights?

If there is a risk of a person falling more than 2 metres, the work is high risk construction work under WHS Regulations s.291(a) and a SWMS is mandatory before it starts. The test is the fall risk, not the job title, so roofers, scaffolders, carpenters and painters trigger it routinely. Here is how the 2 metre rule works in every state.

Do I Need a SWMS for Demolition Work?

Demolition work almost always requires a SWMS. Knocking down load-bearing or structural elements is high risk construction work under s.291(c) of the WHS Regulations, and older buildings often add asbestos disturbance (s.291(d)) and temporary structural support (s.291(e)) to the same job. This guide explains when each trigger applies, what the SWMS must contain, and how Victoria and WA differ.

Do I Need a SWMS for Confined Spaces?

Yes. Work in or near a confined space is high risk construction work under s.291(f) of the model WHS Regulations, so a SWMS must be prepared before the work starts. Confined space jobs often trigger other high risk categories at the same time, including contaminated or flammable atmospheres and shafts or trenches deeper than 1.5 metres. Here is what the law actually requires.

Do I Need a SWMS for Electrical Work?

Yes, if the job is construction work on or near energised electrical installations or services. That is high risk construction work under s.291(k) of the model WHS Regulations, and a Safe Work Method Statement must be prepared before work starts. Your electrical licence does not replace this duty. Here is what triggers the requirement, what the SWMS must cover, and how it varies by state.

Do I Need a SWMS for Excavation and Trenching?

Excavating a shaft or trench deeper than 1.5 metres, or any tunnel, is high risk construction work under the model WHS Regulations — and several other s.291 categories catch shallower digs. Here is when the law requires a SWMS for excavation, and what it must contain.
