SWMS requirements by state and territory

Two systems, not one

Australia has a model Work Health and Safety framework that most jurisdictions have adopted, and one large state that has not. Getting this wrong is the most common mistake in SWMS guidance online, and it matters because the categories that trigger a SWMS are not identical between the two.

New South Wales, Queensland, South Australia, Tasmania, the Australian Capital Territory, the Northern Territory and Western Australia all operate versions of the model WHS Act and Regulations. Western Australia came last, commencing its WHS laws in 2022, and retains some differences in detail.

Victoria operates the Occupational Health and Safety Act 2004 and the OHS Regulations 2017. The SWMS obligation exists there too, but under Victorian definitions.

What this means in practice

For most trades on most jobs, the practical requirement is the same: identify the high risk construction work, write a site-specific SWMS before starting, consult the workers, have them sign on, keep it available, and review it when things change.

Where it bites is at the margins — whether a particular activity falls inside the definition, and what a principal contractor is required to do with your SWMS. If you work across a border, do not assume the document that satisfied one regulator satisfies the other without checking.

Who to check with

The regulator for your jurisdiction is the authority on this:

• New South Wales — SafeWork NSW
• Victoria — WorkSafe Victoria
• Queensland — Workplace Health and Safety Queensland
• Western Australia — WorkSafe WA (Department of Energy, Mines, Industry Regulation and Safety)
• South Australia — SafeWork SA
• Tasmania — WorkSafe Tasmania
• Australian Capital Territory — WorkSafe ACT
• Northern Territory — NT WorkSafe
• National guidance material — Safe Work Australia (which writes the model laws but does not regulate or enforce them)

A note on Safe Work Australia

Safe Work Australia develops the model WHS laws and publishes model codes of practice, but it is not a regulator. It cannot inspect your site, issue a notice or answer a question about your specific job. Its guidance is excellent background; your state regulator is the one whose view counts.

Common questions

Are SWMS requirements the same in every Australian state?

Almost. NSW, QLD, SA, TAS, ACT, NT and WA run versions of the model WHS Regulations. Victoria has never adopted the model laws and runs its own OHS Act 2004 and OHS Regulations 2017, with its own definition of high risk construction work.

Does a SWMS written for NSW work in Victoria?

The structure carries over, but the trigger categories and some obligations differ, and the document still has to be site-specific to the Victorian job. Check the work against Victoria's definition rather than assuming the NSW one applies.

Who enforces SWMS requirements?

The work health and safety regulator in the state or territory where the work is being done. Safe Work Australia writes the model laws but does not enforce them.
