How to Write a Safe Work Method Statement (SWMS): A Step-by-Step Guide

What is a SWMS?

A Safe Work Method Statement (SWMS) is a legally defined document that sets out high-risk construction work step by step: the tasks involved, the hazards each task creates, the control measures that reduce those risks, and how the controls will be put into practice on site. It's not a generic risk assessment — it's a task-specific document prepared before the work starts and used while the work is underway.

If you're still working out whether your job even needs a SWMS rather than a JSEA, that's a separate question — see JSEA vs SWMS in Victoria. This guide assumes you already know you need one, and walks through how to actually write it so it holds up on site and at audit.

What must a SWMS include?

A SWMS isn't a free-form template — its content is set by regulation, not by convention. Under the model Work Health and Safety (WHS) Regulations that apply in NSW, Queensland, SA, WA, Tasmania, the ACT, the NT and Commonwealth workplaces, a person conducting a business or undertaking (PCBU) doing high-risk construction work (HRCW) must ensure a SWMS is prepared that meets specific content requirements before work begins.

Required element	What it means in practice
Identifies the high-risk work	States which of the defined HRCW activities the task falls under (e.g. work at height over 2m, trenching, work near live electrical services)
States the hazards and risks	Names the specific hazards the task creates, not generic workplace hazards
Describes the control measures	Sets out how each risk will be eliminated or minimised, following the hierarchy of controls
Describes how controls are implemented	Explains who does what, with what equipment, in what sequence
Is accessible and comprehensible	Written in plain language the people doing the work can actually read and use on site

This is drawn directly from Safe Work Australia's model WHS Regulations and its published information sheet on preparing a SWMS for HRCW, and from the equivalent state regulation (for example, reg 299 of the Queensland WHS Regulation 2011, mirrored across the harmonised states). PCBUs are required to prepare, keep, comply with, and review their SWMS — not just produce one and file it away.

Does Victoria require a SWMS?

Yes — but not under the "WHS Regulations" that the table above refers to. Victoria never adopted the model WHS Act (see Does the WHS Act apply in Victoria?), so there's no Victorian "WHS Regulation 299." Instead, Victoria's own Occupational Health and Safety Regulations 2017 contain a near-identical, self-contained SWMS regime:

• Reg 322 defines high risk construction work — 19 categories, closely matching the harmonised list (falls over 2m, demolition, asbestos disturbance, confined spaces, trenches over 1.5m, work near energised electrical installations, and so on).
• Reg 324 defines what a SWMS is, requiring it to identify the HRCW, state the hazards and risks, sufficiently describe the control measures, describe how those measures are implemented, and be set out in a way that's accessible and comprehensible to the people using it.
• Reg 327 requires the SWMS to be prepared before HRCW starts, and requires work to stop immediately if it isn't being carried out in accordance with the statement.
• Reg 328 requires the SWMS to be reviewed and revised.

So the content test is, in substance, the same test as the harmonised states — Victoria just legislates it through its own Act and its own regulation numbers, not the model WHS framework. "Victoria doesn't require SWMS" is a myth worth killing; the more accurate statement is that Victoria requires one under a different piece of legislation, for the same category of work.

How do you write a SWMS? Step by step

A SWMS is built from the site outward, not from a template inward. Work through it in this order:

1. Confirm the scope. Name the specific job (not the whole project) — for example, "trenching and laying 40m of compressed air line through the east workshop floor," not "site works."
2. Break the task into a sequence of steps. List the actual physical steps a worker will do, in order — mark-out, isolation, excavation, pipe-laying, backfill, reinstatement. Vague, merged steps produce vague, useless controls later.
3. Identify the hazards at each step. For every step, ask what could go wrong: services strike, trench collapse, plant movement, manual handling, proximity to live electrical infrastructure. Do this on site or with someone who knows the site — not from memory in an office.
4. Identify the control measures for each hazard. Work down the hierarchy of controls: eliminate first, then substitute or isolate, then engineering controls, then administrative controls and PPE last. A SWMS that lists only "wear PPE" and "be careful" as controls won't meet reg 324's requirement to sufficiently describe control measures.
5. Name who's responsible. Each control needs an owner — who checks isolation is complete, who supervises the confined space entry, who has the authority to stop the job. A SWMS with no named responsibility is a SWMS nobody actually owns.
6. Consult the people doing the work. The workers who'll carry out the task, and their health and safety representative, should have input before the SWMS is finalised — not just be handed it on the day.
7. Set it out clearly and get it signed off before work starts. Every worker performing the task should read (or be talked through) and sign the SWMS before HRCW begins. This is also the point where the document earns its accessibility requirement — if it needs a law degree to parse, it's failed step 7 regardless of what's in it.
8. Review and revise it when anything changes. A new hazard, a changed method, an incident, or a worker or HSR raising a concern should trigger a review — not wait for the next audit.

Common mistakes that make a SWMS non-compliant or useless

Most SWMS problems aren't dramatic legal failures — they're paperwork that technically exists but does nothing.

• Too generic to be task-specific. A SWMS pulled from a template library and left unedited doesn't identify the actual hazards on your site. Safe Work Australia's own review of SWMS use found many workers viewed the SWMS "as unnecessary paperwork, rather than a key step in managing the risks of hazardous work" — usually because the document in front of them didn't describe their actual job.
• Merged with unrelated tasks. Bundling multiple different HRCW activities, or non-HRCW tasks, into one SWMS to save paperwork dilutes the specificity the regulation requires. Keep it to the task at hand — that's also the point of the SWMS/JSEA split covered in JSEA vs SWMS.
• Controls that are just instructions to "be safe." "Take care," "wear appropriate PPE," and "follow safe work practices" are not control measures — they don't describe what will actually be done to reduce the risk.
• Never actually read on site. A signed SWMS sitting in a folder in the site office, while the crew works from memory or verbal instruction, satisfies nobody — not the regulator, and not the person who gets hurt when the method changes but the document doesn't.
• No review trigger. A SWMS written once at project start and never revisited, even after site conditions, plant, or personnel change, stops matching the job it was written for.
• No named responsibility. If nobody on the SWMS is actually accountable for checking a control is in place, it's a description of intentions, not a work method.
