SWMS requirements in Western Australia
In Western Australia, a SWMS must be prepared before any high-risk construction work starts. Western Australia follows the model WHS laws, and its SWMS duties are in the Work Health and Safety (General) Regulations 2022 (WA): Regulations 299 to 303 (prepare, follow, give the principal contractor a copy, review, keep) and 312 (principal contractor obtains it).

What the law requires
- Prepare a SWMS before the high-risk construction work starts (regulation 299).
- It must identify the high-risk work, the hazards and risks, the control measures, and how they will be put in place, monitored and reviewed, in a way the workers who use it can understand (regulation 299).
- Make sure the work is done the way the SWMS says, and stop it if it isn't, as soon as it's safe to (regulation 300).
- On a construction project, give the principal contractor a copy before the work starts (regulation 301). The principal contractor must take reasonable steps to get one (regulation 312).
- Review the SWMS, and revise it as needed, whenever its control measures change (regulation 302).
- Keep a copy until the work is finished, and for at least 2 years after any notifiable incident connected with it (regulation 303).
These are the model WHS Regulations' duties. The Work Health and Safety (General) Regulations 2022 (WA) uses the same numbers.
Where Western Australia differs from the model
