Quick answer: Yes, one SWMS can cover multiple related tasks or High Risk Construction Work activities. The limit is not a legal number — it is whether the document stays specific enough for workers to actually understand and apply it on site.
Last reviewed: June 2026 by the BlueSafe Technical Team. Reflects current Australian WHS requirements.
This is one of the most practical questions businesses ask when putting a SWMS together for a job that spans several types of high-risk work. The answer is straightforward: combining activities into a single SWMS is allowed and sometimes makes sense. The problems start when that approach is taken too far.

Why combining tasks in a SWMS can make sense
High-risk construction work often involves overlapping activities. A scaffolding erection job might include working at heights, use of powered mobile plant, and work near overhead lines — all at the same time, carried out by the same crew, in the same work area.
Writing three separate SWMS documents for each of those HRCW categories could produce unnecessary duplication. The work sequence, the hazard controls, and the supervision arrangements are shared. Keeping them in a single, well-structured document can make the SWMS easier to manage and easier for workers to follow.
The WHS regulations require that a SWMS identify each HRCW activity, the associated hazards, and the control measures before work starts. They do not prohibit listing more than one HRCW activity in the one document.
The problem with catch-all SWMS documents
The difficulty is not with combining tasks in principle — it is with doing it in a way that produces a document no one can use.
A catch-all SWMS typically looks like this:
- it lists every possible HRCW category, many of which do not apply to the actual job
- the controls are written in broad language such as "follow manufacturer instructions" or "use appropriate PPE"
- there is no clear connection between a specific step in the work and the control that applies at that step
- the same generic hazard list is reused from job to job without site-specific adjustment
This kind of document does not protect workers. It cannot. Workers reading it cannot identify which part applies to what they are doing, what controls they are actually required to implement, or who is responsible at each stage.
Regulators treat an overly broad SWMS the same way they treat no SWMS at all: as a failure to manage the risk.
See What Makes a SWMS Site-Specific? for more detail on why generic documents fall short.
The test that actually matters
The practical test for whether a multi-task SWMS is working is simple: can the workers doing the job read it, understand it, and apply it during the work?
If the answer is yes, the document is doing its job.
If the answer is no — because it is too long, too vague, too general, or tries to cover too many different things at once — the document is not compliant regardless of how many tasks it lists.
This is consistent with the way the WHS Regulations frame the requirement. The SWMS must be communicated to workers before they start the work, and workers must have the opportunity to ask questions and receive an explanation they can understand. A document that confuses workers at briefing is not an adequate SWMS.
When to keep tasks together
Tasks are generally appropriate to combine in a single SWMS when:
- they are part of the same work sequence or phase of a project
- they are carried out by the same crew or the same PCBU
- the hazards and control measures overlap significantly
- combining them produces a cleaner, more logical document, not a longer or more complicated one
- the document can still identify each HRCW activity clearly within the work steps
A scaffolding SWMS that covers erection, use, and dismantling within the same document is a good example of tasks that naturally belong together.
When to split into separate SWMS documents
Consider preparing separate documents when:
- tasks involve distinctly different hazards that require very different controls
- different subcontractors or crews are responsible for each activity
- the work occurs at different times or in different locations on the site
- adding another activity to the document would require controls to become vague in order to cover all scenarios
- the combined document becomes long enough that workers struggle to find the section relevant to their task
A common split worth making is between civil work and structural work, or between electrical work and the construction tasks happening nearby. Even when these occur on the same site, the hazard profiles, competency requirements, and controls are different enough that a combined document tends to become unworkable.
Balancing practicality and specificity
There is no single right answer for every job. The balance between keeping documents manageable and keeping them specific is a judgment call that depends on the work, the site, and the workers involved.
Some principles that help:
Structure the SWMS by work stage. For each stage, list only the hazards and controls that apply to that stage. This keeps the document focused without requiring a separate document for every activity.
Name the HRCW categories explicitly. Do not leave it to workers to work out whether the document applies to what they are doing. State clearly which HRCW categories the document covers.
Cut what does not apply. A SWMS that lists 14 HRCW categories for a job that only involves three is a sign the template was not reviewed. Remove what does not apply.
Keep the language direct. Controls should say what workers will actually do, not what they should consider doing. "Install perimeter edge protection before work begins" is a control. "Consider appropriate fall prevention measures" is not.

Frequently asked questions
Can a single SWMS cover more than one high-risk construction work activity?
Yes. A single SWMS can cover multiple related HRCW activities provided the document remains specific, clear, and practical for the workers using it. The test is whether the people doing the job can read it and actually follow it on site.
What is the risk of making a SWMS cover too many tasks?
An overly broad SWMS becomes unworkable. Controls become generic, hazards get missed, and workers cannot identify which steps and precautions apply to what they are doing. Regulators treat this as inadequate documentation.
When should you split one SWMS into two or more separate documents?
Split the SWMS when tasks involve very different hazards, different control measures, different crews, or different locations. If adding another activity makes the document unclear or forces controls to become vague, a separate SWMS is the better option.
Does Australian WHS law specify how many tasks one SWMS can cover?
No. The law does not set a fixed limit. The requirement is that the SWMS must identify the high-risk activities, the hazards, and the controls, and must be communicated to workers before work starts. The document must be usable in practice.
