Quick answer: A SWMS is required before High Risk Construction Work starts. The key issue is not the trade name, but whether the task falls into one or more of the HRCW categories in WHS law.
Last reviewed: March 2026 by the BlueSafe Technical Team. Reflects current Australian WHS requirements.
Many businesses know they need a SWMS "for high-risk work" but are less clear on what actually triggers that duty. The answer comes back to whether the task is High Risk Construction Work under the relevant WHS framework.

What counts as High Risk Construction Work?
High Risk Construction Work is not a general label for "dangerous jobs". It has a specific legal meaning. If the construction task falls into one of the listed HRCW categories, a SWMS is required.
Some of the most common categories are:
- HRCW #1: risk of a person falling more than 2 metres
- HRCW #4: asbestos disturbance or removal
- HRCW #6: work in a confined space
- HRCW #7: trenches deeper than 1.5 metres
- HRCW #12: work on or near energised electrical installations or services
- HRCW #15: work in an area with movement of powered mobile plant, traffic, or public interaction
- HRCW #16: construction work involving powered mobile plant
How to decide whether a SWMS is required
Use a practical test:
- Is this construction work?
- Does the task match one of the HRCW categories?
- If yes, has the SWMS been prepared before the job starts?
The same trade may move in and out of the SWMS requirement depending on the task. For example, an electrician doing standard fit-off work may not trigger HRCW on one job, but live testing on another job may clearly trigger HRCW #12.
Common high-risk scenarios
| Task type | Likely HRCW category | Why a SWMS is required |
|---|---|---|
| Roof work and edge work | #1 | Risk of falls over 2 metres |
| Asbestos removal or disturbance | #4 | Specific asbestos trigger |
| Tank, pit, shaft, or manhole entry | #6 | Confined space entry |
| Deep excavation or trenching | #7 | Ground collapse and burial risk |
| Live electrical testing or fault finding | #12 | Energised electrical risk |
| Construction work near public traffic | #15 | Vehicle and public interface risk |
| Excavators, EWPs, forklifts, cranes | #16 | Powered mobile plant in construction |
What the SWMS should cover
A compliant SWMS should explain:
- the work steps in the order they will happen
- the specific high-risk activities involved
- the hazards and potential consequences
- the controls used to reduce those risks
- who is responsible for putting controls in place
- how the SWMS will be monitored and reviewed
It should also match the actual site conditions, not just the generic task.
One task can trigger several HRCW categories
Many real jobs involve more than one trigger at the same time. For example:
- roof-mounted electrical installation can involve HRCW #1 and #12
- trenching near live underground services can involve HRCW #7 and #12
- road construction with excavators can involve HRCW #15 and #16
When that happens, the SWMS should address the combined risk picture rather than treating each trigger in isolation.
State and territory variations
Most jurisdictions use the Model WHS structure for HRCW, but local regulator guidance still matters.
| Jurisdiction | Regulator | Key note |
|---|---|---|
| NSW | SafeWork NSW | Model WHS framework applies |
| VIC | WorkSafe Victoria | Victoria uses a different legislative framework |
| QLD | Workplace Health and Safety Queensland | Model WHS framework applies |
| SA | SafeWork SA | Model WHS framework applies |
| WA | WorkSafe WA | Model WHS framework applies with local variations |
| TAS | WorkSafe Tasmania | Model WHS framework applies |
| ACT | WorkSafe ACT | Model WHS framework applies |
| NT | NT WorkSafe | Model WHS framework applies |
Always check the current guidance for the jurisdiction and site.

Frequently asked questions
What is High Risk Construction Work?
It is construction work that falls into one of the listed HRCW categories in WHS law.
Do you need a SWMS for every HRCW task?
Yes. If the task is HRCW, the SWMS must be prepared before the work begins.
What are common HRCW triggers?
Falls, asbestos, confined spaces, deep trenches, energised electrical work, road corridors, and powered mobile plant are some of the most common triggers.
Can one SWMS cover several high-risk activities?
Yes, provided it properly covers the full task, the hazards, and the controls for each relevant activity.
SWMS templates for High Risk Construction Work
- General Working at Heights SWMS for tasks involving falls risk and access above 2 metres.
- Confined Spaces SWMS for entry, work, and controls in tanks, pits, shafts, and similar spaces.
- Excavation and Trenching SWMS for trench and excavation work where collapse and buried-service risks must be controlled.
- Electrical Installation and Maintenance SWMS for electrical work that may involve energised systems, isolation, and testing controls.
