The short answer: if you carry out high risk construction work, you need a Safe Work Method Statement before the work starts. It does not matter whether you are a sole trader or a hundred-person company, and it does not matter how quick the job is. The trigger is the type of work, not the size of the business.
The rule in one line
A SWMS is required whenever any of the 18 categories of high risk construction work is carried out (WHS Regulations reg 291 and reg 299; in Victoria, the OHS Regulations 2017). If your work involves even one of those categories, a SWMS has to be prepared, followed on site, and kept available while the work is done.
Who the duty actually falls on
The duty sits with the PCBU (person conducting a business or undertaking) that is carrying out the high risk construction work. In plain terms:
- • If you are a subcontractor doing the high risk work, the SWMS is yours to prepare, not the builder's
- • The principal contractor must be given the SWMS before the work starts, and usually reviews it
- • Workers doing the work must be consulted, and must be able to get to the SWMS on site
- • A sole trader doing high risk construction work is a PCBU too, so the duty still applies
This is the part that catches people out. Subbies often assume the builder writes the safety paperwork. The builder manages the site, but the SWMS for your high risk work is your responsibility.
The trades that need one on almost every job
Because the categories are about the work, some trades trigger a SWMS on nearly every site:
- • Roofers, solar installers, and anyone on a roof above 2 metres
- • Electricians working on or near energised installations
- • Plumbers and excavators working in trenches deeper than 1.5 metres or in confined spaces
- • Demolition crews removing load-bearing structures or disturbing asbestos
- • Carpenters and formworkers doing structural work at height
- • Concreters and others working around powered mobile plant
Even trades that do not think of themselves as high risk get caught: a painter on a trestle above 2 metres, a tiler on a balcony edge, a bricklayer on a scaffold. The moment there is a risk of falling more than 2 metres, you are in scope.
When you do NOT need a SWMS
General construction work that is not one of the 18 categories does not require a SWMS. You still have to manage the risks and you may still need a safe work procedure or a risk assessment, but the specific legal duty to prepare a SWMS is only triggered by high risk construction work. If you are not sure which bucket your job falls in, use the SWMS checker.
What "having a SWMS" really means
Preparing the document is only half of it. The Regulations also require you to carry out the work in accordance with the SWMS, stop and revise it if the work changes, and keep a copy accessible while the work is done (provisions 300 to 303; the exact numbering varies slightly between states). A SWMS sitting unread in the ute does not meet the duty.
The fastest way to be covered
If you need one, you can start from a free blank SWMS template and write it yourself, or generate a site-specific SWMS for your trade and state in minutes. Not sure whether this job needs one at all? Check in 30 seconds first.
