Not every construction job needs a Safe Work Method Statement, but certain kinds of work automatically do. These are called triggers, specific tasks or conditions that, if present on your job, make a SWMS a legal requirement rather than a choice. Under the Model WHS Regulations, there are 19 defined triggers, known as high-risk construction work categories, and if your job falls into even one of them, a Safe Work Method Statement isn’t optional.
This guide covers all 19, in plain language, so you know exactly where your job stands before work starts.
What Counts as “High-Risk Construction Work”?
The trigger for needing a SWMS is the type of work being done, not the size of your business or the size of the job. A two-person crew doing a small residential job is covered by the same rules as a large commercial site if the work itself falls into one of the high-risk categories. We’ve covered the most common triggers safety managers ask about here.
This guide will cover everything else.
The 19 Categories of High-Risk Construction Work
1. Work with a Risk of a Fall More Than 2 Metres
Any work with a risk of a person falling more than 2 metres requires a SWMS. The trigger is the risk of the fall, not simply working at height, so proper edge protection or engineering controls are part of assessing whether this category applies.
2. Work Carried Out on a Telecommunications Tower
Covers construction, maintenance, or alteration work on telecommunications towers, given the fall and structural risks involved.
3. Demolition of a Load-Bearing Element
Any demolition work involving an element of a structure that is load-bearing falls into this category due to the risk of uncontrolled collapse.
4. Demolition Related to Physical or Mechanical Integrity
Separate from load-bearing demolition, this covers demolition of any element related to a structure’s broader physical or mechanical integrity.
5. Disturbance of Asbestos
Any work likely to disturb asbestos-containing materials, common in older buildings, requires a SWMS in addition to any separate asbestos removal licensing requirements.
6. Structural Alterations or Repairs Requiring Temporary Support
Covers work where a structure’s load-bearing elements are altered and temporary shoring or propping is required to prevent collapse.
7. Work in a Confined Space
Confined spaces carry risks including limited oxygen, toxic atmospheres, and difficult emergency access.
8. Work in or Near a Trench or Shaft Deeper Than 1.5 Metres
Trench collapse is one of the most common causes of serious injury in excavation work, which is why this threshold is specifically called out.
9. Work On or Near a Tunnel
Any work carried out on or near a tunnel, given the confined, high-risk nature of underground construction.
10. Use of Explosives
Any construction work involving the use of explosives is automatically classified as high-risk.
11. Work On or Near Pressurised Gas Distribution Mains and Piping
Covers work in proximity to pressurised gas infrastructure, including underground services that may not be immediately visible.
12. Work On or Near Chemical, Fuel, or Refrigerant Lines
A separate category from gas mains, covering chemical, fuel, or refrigerant piping specifically.
13. Work On or Near Energised Electrical Installations or Services
Includes work near live wiring, switchboards, or other energised electrical infrastructure where contact or arc flash is a genuine risk.
14. Work in an Area That May Have a Contaminated or Flammable Atmosphere
Covers work in environments where the atmosphere itself may present a contamination or flammability risk, separate from confined space risk.
15. Tilt-Up or Precast Concrete Work
Covers the lifting, moving, and placement of tilt-up panels or precast concrete elements, where structural failure or crush risk is significant.
16. Work On, In, or Adjacent to a Road, Railway, Shipping Lane, or Other Traffic Corridor
Applies to work with exposure to moving traffic of any kind, including pedestrians, vehicles, or trains.
17. Work in an Area With Movement of Powered Mobile Plant
Includes work in areas where excavators, forklifts, cranes, or similar powered mobile plant are operating.
18. Work In or Near Water or Other Liquid With a Risk of Drowning
Applies to work near dams, waterways, or other bodies of liquid where drowning is a realistic risk.
19. Diving Work
Any construction-related diving work is automatically high-risk under the Regulations.
What a Compliant SWMS Must Include for High-Risk Work
Regardless of which category applies, a compliant SWMS needs to cover:
- The specific high-risk work being carried out
- The hazards associated with that work
- The control measures put in place to manage those hazards
- Who is responsible for implementing and monitoring those controls
- How and when the SWMS will be reviewed if conditions change
How MiSAFE Simplifies This
Working out which of the 19 categories apply to a job, then building a compliant SWMS around it, is exactly what MiSAFE SWMS is built for. Our AI-assisted tool gets a compliant SWMS built in minutes, not hours, and every worker signs on by scanning the QR code on the document itself, capturing a version-locked signature every time.
Frequently Asked Questions
What is high-risk construction work under Australian law?
High-risk construction work is one of 19 categories of construction activity defined in the Model WHS Regulations that require a Safe Work Method Statement before work begins, due to the elevated risk involved.
Do I need a SWMS for every high-risk category?
Yes. If any part of your job falls into one of the 19 categories, a SWMS is legally required for that work, regardless of the size of your business or the job itself.
What happens if I don’t have a SWMS for high-risk work?
Working without a required SWMS is a breach of your WHS obligations and can result in regulatory penalties, stop-work directions, and increased liability if an incident occurs.
