How to write a SWMS: a step-by-step guide for Australian businesses (2026)

Plenty of guides will tell you what a Safe Work Method Statement is. Far fewer tell you how to actually write one that a WHS inspector would accept and, more importantly, that keeps your crew safe. If you already need the background — what a SWMS is and the 18 categories of high-risk construction work that trigger one — start with SWMS explained: when you need one and what it must contain. This guide assumes you know you need a SWMS, and walks through writing it, step by step.

Before you start: who has the duty

Under the model Work Health and Safety (WHS) Regulations, the person conducting a business or undertaking (PCBU) carrying out high-risk construction work must ensure a SWMS is prepared before the work starts, and that the work is then done in accordance with it. You cannot delegate that duty away by buying a template. A template can be a starting point, but the finished SWMS has to describe your job, on your site, with your crew and plant. WHS laws are applied and enforced by the regulator in your state or territory, so check your jurisdiction for anything specific to where you are working.

Step 1 — Name the high-risk construction work

Start by stating plainly which high-risk construction work this SWMS covers. Is it work where someone could fall more than two metres? Work on or near energised electrical installations? A trench deeper than 1.5 metres? Demolition, asbestos, mobile plant, work near traffic? Name the specific activity, not "construction". A generic SWMS that tries to cover every job at once is the classic failure — it names none of the real hazards of the work in front of you, because it was written to apply to everything.

Step 2 — Involve the workers who will do it

A SWMS written at a desk by someone who will never be on site is weaker, and the WHS laws expect consultation. The people who do the work know the practical hazards — the awkward access, the overhead service, the point in the sequence where it gets dangerous. Involve them, and you get a document that is both more accurate and more likely to be followed, because the crew helped write it.

Step 3 — Identify the hazards and risks

For the activity you named, list what could actually cause harm and how. Be specific to the site: the fragile roof sheet, the unprotected edge, the live cable overhead, the deep face of the trench, the public footpath below. For each hazard, note who could be harmed and how seriously. This is the heart of the document — a SWMS that skips or generalises the hazards is not really a risk assessment at all.

Step 4 — Choose controls using the hierarchy

For every hazard, set out the control measures, and work down the hierarchy of control rather than jumping straight to PPE. First ask whether the hazard can be eliminated — can the work be done another way, or at ground level? If not, can you substitute, isolate, or use an engineering control (a scaffold with edge protection, a trench shield, a physical exclusion zone)? Administrative controls (a safe sequence, a permit, a spotter) and personal protective equipment come last, not first. Regulators expect to see that you reached for the higher-order controls before relying on a harness or a hi-vis vest.

Step 5 — Say how the controls will be put in place, monitored and reviewed

This is the step most SWMS skip. It is not enough to list controls — you have to describe how each will actually be implemented, who is responsible, and how you will check it stays in place as the job runs. "Edge protection installed" is a control; "leading-hand to confirm edge protection is complete and inspected before anyone works within two metres of the edge, and to re-check after any change" is a control that will actually happen.

Step 6 — Write it so the crew can understand it

A SWMS is a working document for the people doing the job, not a legal essay for a filing cabinet. Use plain language. Keep it as short as the work allows. If your crew includes workers whose first language is not English, make sure the SWMS can be understood by them — that is an explicit expectation, not a nicety. A forty-page pack nobody reads protects no one.

Step 7 — Induct every worker and record it

Before anyone starts the high-risk work, every worker must be inducted into the SWMS — talked through the hazards and the method, with the chance to raise anything. There is no single mandated signature, but recording each worker's sign-on is the standard way to evidence the induction happened, and principal contractors almost always require it. That record is also what you will reach for if there is ever an incident or a claim: proof the person doing the work knew the risk and the control.

Step 8 — Keep it on site, and review it when things change

The SWMS stays at the workplace while the high-risk work is carried out, and it must be reviewed — and revised if needed — whenever the work method, the plant, or the site conditions change. If the sequence changes, if a different piece of plant turns up, if the weather forces a different approach, the SWMS has to catch up. Keep it until the work is complete; if a notifiable incident happens in connection with the work, keep it for at least two years from the incident.

The difference between a SWMS that works and one that just exists

Every step above comes back to one idea: the SWMS has to match the real job. The documents inspectors challenge, and the ones that fall apart after an incident, are the generic ones that describe a job nobody actually did. Keep it specific, keep the sign-ons against it, revise it when things change — and it becomes what it is meant to be: the thing that keeps your crew safe and shows you managed the risk. If you also carry public liability or other cover, those same records are what an insurer may ask to see after a claim, which is another reason to keep them current and findable.

Where Complys fits

Writing a proper SWMS by hand for every job is exactly the kind of work Complys was built to take off you. It builds a job-specific SWMS around the high-risk work you select — the hazards, the controls in the right order, the implementation and review — in minutes, captures each worker's sign-on so the induction is evidenced, and keeps every version on file and current, so the SWMS on site is always the right one. It sits alongside your WHS records and your contractor documents, and you can create and manage your SWMS with Complys free for 90 days.
