Quick answer: Under Australian WHS Regulations, there are 18 activities classified as High Risk Construction Work (HRCW). If your work involves any of them, you are legally required to prepare a Safe Work Method Statement (SWMS) before starting.

Under Australian Work Health and Safety (WHS) Regulations, not every construction task requires a Safe Work Method Statement (SWMS). However, there are 18 specific activities classified as High Risk Construction Work (HRCW).
If your work involves any of these activities, you are legally required to prepare a SWMS before work commences. Failure to do so is a breach of the law.
The 18 High-Risk Activities
Check this list carefully. If your project involves one or more of these, you need a SWMS.
- Risk of a person falling more than 2 metres. (Note: In some states, this height may vary, but 2m is the national model standard).
- Work carried out on a telecommunication tower.
- Demolition of an element of a structure that is load-bearing or otherwise related to the physical integrity of the structure.
- Work that involves, or is likely to involve, the disturbance of asbestos.
- Structural alterations or repairs that require temporary support to prevent collapse.
- Work that is carried out in or near a confined space.
- Work that is carried out in or near a shaft or trench with an excavated depth greater than 1.5 metres.
- Work that is carried out in or near a tunnel.
- Use of explosives.
- Work that is carried out on or near pressurised gas distribution mains or piping.
- Work that is carried out on or near chemical, fuel or refrigerant lines.
- Work that is carried out on or near energised electrical installations or services.
- Work that is carried out in an area that may have a contaminated or flammable atmosphere.
- Work that involves tilt-up or precast concrete.
- Work that is carried out on, in or adjacent to a road, railway, shipping lane or other traffic corridor that is in use by traffic other than pedestrians.
- Work that is carried out in an area at a workplace in which there is any movement of powered mobile plant.
- Work that is carried out in an area in which there are artificial extremes of temperature.
- Work that is carried out in or near water or other liquid that involves a risk of drowning.
What If My Job Involves Multiple Risks?
It is common for a single job to involve multiple high-risk activities. For example, an electrician working on a ladder near a road might trigger three categories:
- Risk of falling > 2m.
- Work on energised electrical installations.
- Work adjacent to a road.
In this case, your SWMS must address all relevant hazards. You do not need three separate documents; a single, comprehensive SWMS that covers all aspects of the job is preferred.
State and Territory Variations
The information on this page is based on the Model WHS Regulations published by Safe Work Australia, which have been adopted (with minor variations) by most states and territories.
| Jurisdiction | WHS regulator | Key notes |
|---|---|---|
| NSW | SafeWork NSW | Adopted Model WHS Regulations; 2m fall height threshold |
| VIC | WorkSafe Victoria | Uses OHS Act 2004 — HRCW provisions differ slightly |
| QLD | Workplace Health and Safety Queensland | Adopted Model WHS Regulations |
| SA | SafeWork SA | Adopted Model WHS Regulations |
| WA | WorkSafe Western Australia | Adopted Model WHS Regulations (2022) |
| TAS | WorkSafe Tasmania | Adopted Model WHS Regulations |
| ACT | WorkSafe ACT | Adopted Model WHS Regulations |
| NT | NT WorkSafe | Adopted Model WHS Regulations |
Always verify requirements with your state regulator, as fall height thresholds and other specifics may vary.

Frequently asked questions
What are the 18 high-risk construction work activities?
The 18 HRCW activities are defined in the WHS Regulations and cover work at heights, asbestos disturbance, confined spaces, trenching, use of explosives, energised electrical work, and 12 other specific categories. The full list appears above.
Do I need a SWMS for all 18 high-risk activities?
Yes. A SWMS must be prepared before any HRCW begins. A JSA alone does not satisfy this legal requirement.
What happens if I don't have a SWMS?
Failing to prepare a SWMS before HRCW is a breach of WHS Regulations. Penalties can include on-the-spot fines, enforcement notices, and prosecution — with fines for a PCBU reaching hundreds of thousands of dollars.
Do the 18 activities differ by state?
The categories are based on the Model WHS Regulations adopted nationally. Some states have minor variations in thresholds or additional requirements — always check with your state regulator.
How to get the right SWMS for your work
Identifying the risk is the first step. Managing it is the second. BlueSafe offers a vast library of SWMS templates specifically designed to cover these 18 high-risk activities, ensuring you can get to work quickly and legally.
