Quick answer: If High Risk Construction Work is underway without a SWMS on site, the work can be stopped immediately, the PCBU and workers may face significant fines, a principal contractor can remove you from the project, and liability increases sharply if an incident occurs.
Last reviewed: June 2026 by the BlueSafe Technical Team. Reflects current Australian WHS requirements.
Missing a SWMS for High Risk Construction Work is not a minor administrative oversight. It is a breach of the Work Health and Safety Act and Regulations, and WHS inspectors treat it seriously. Understanding what can happen — and what an inspector looks for — helps businesses avoid consequences that are entirely preventable.
At a glance
| Consequence | Who it affects |
|---|---|
| Improvement notice | PCBU, principal contractor |
| Prohibition notice (work stopped) | PCBU, site as a whole |
| Monetary fines and penalties | PCBU (business), officers, workers |
| Removal from site | Subcontractors, individual workers |
| Increased liability if incident occurs | PCBU, officers, supervisors |
| Criminal prosecution in serious cases | Individuals and bodies corporate |
The legal requirement
Under the WHS Regulations, a PCBU conducting High Risk Construction Work (HRCW) must ensure a SWMS is prepared before that work begins, is available on site, and is followed while the work is carried out.
There is no grey area. If any of those three conditions are not met — prepared, on site, and followed — the legal duty has not been satisfied.
Regulator powers: what an inspector can do
WHS inspectors have broad powers on site. When they arrive and ask for a SWMS, they are not simply doing a paperwork audit. They are checking whether the actual work being done is being managed safely.
Improvement notices
An improvement notice requires the PCBU to remedy a breach within a set timeframe. For a missing or inadequate SWMS, an inspector may issue an improvement notice requiring one to be prepared and implemented before the work continues.
See our guide on improvement notices and prohibition notices for more detail on how these notices work, what they require, and how to respond.
Prohibition notices
A prohibition notice is more serious. It stops a specific activity immediately when an inspector believes it involves a serious risk of death or serious injury. If HRCW is underway without a SWMS, or if the SWMS in place is so inadequate it provides no real control, a prohibition notice can be issued on the spot.
Work must stop and cannot resume until the inspector is satisfied that the risk has been adequately addressed. That means a compliant SWMS must be in place, workers must be briefed on it, and the controls must actually be implemented before the job restarts.
What an inspector looks for
Inspectors do not only check whether a document called a SWMS exists. They also check:
- whether the SWMS identifies the actual HRCW activities on this specific site
- whether the hazards listed reflect the real conditions present
- whether the control measures are appropriate and in the hierarchy of controls
- whether the workers have been consulted and have read and signed the document
- whether the controls described in the SWMS are being followed during the work
- whether the SWMS has been updated when conditions or the method changed
A SWMS that was prepared for a different site, refers to the wrong job, or has not been reviewed since conditions changed will often be treated as having no effective SWMS at all.
Penalties and fines
WHS penalties in Australia are significant. They apply to the business (PCBU), to officers of the business, and in some cases to individual workers.
The exact penalty depends on the jurisdiction and the category of breach. The Model WHS Act classifies offences into three categories:
- Category 3 — failing to comply with a health and safety duty, no awareness of the risk of death or serious harm. Penalties for a body corporate can reach $500,000.
- Category 2 — failing to comply with a duty while being aware of a risk of death or serious harm. Penalties for a body corporate can reach $1,500,000.
- Category 1 — reckless conduct exposing a person to risk of death or serious injury. Penalties for a body corporate can reach $3,000,000, and individuals can face gaol time.
For detail on how penalties apply in each state and territory, see our guide on WHS penalties and fines in Australia.
Principal contractors can remove you from site
Beyond regulator enforcement, there are commercial consequences. Principal contractors are responsible under WHS law for managing health and safety across the site. When a subcontractor or self-employed person is carrying out HRCW without a SWMS, the principal contractor is exposed.
As a result, most principal contractors include SWMS requirements in their subcontract agreements. If you are found on site without a required SWMS, the practical outcomes can include:
- being directed to stop work and prepare a compliant SWMS before continuing
- a formal notice of breach under the subcontract
- being removed from the site for the remainder of the project
- reputational damage affecting future tender opportunities
These outcomes are separate from regulator action and can have a direct impact on your business regardless of whether a formal fine is issued.
Increased liability if an incident occurs
If a worker is injured or killed during HRCW and no SWMS was in place, the absence of the document becomes highly significant in any investigation, coronial inquest, prosecution, or civil claim.
The SWMS is part of the risk management process. Without it, there is no documented evidence that the risks were identified, the controls were chosen, or the workers were briefed. That absence:
- makes it harder to demonstrate that a reasonable and practicable approach was taken
- increases the exposure of the PCBU, officers, and supervisors to prosecution
- strengthens claims in civil proceedings that the duty of care was not met
The SWMS is not just a legal box. It is a record of how the job was planned to be done safely. Its absence speaks for itself.
A SWMS that is not being followed is also a breach
It is worth being clear on one point that is often misunderstood. The obligation is not just to have a SWMS on site. It is to follow it.
If the SWMS says that a spotter is required when operating plant near an excavation, and the spotter is absent when an inspector arrives, that is a breach even if the SWMS document is sitting in a folder on the table.
The WHS Regulations require the PCBU to ensure the work is carried out in accordance with the SWMS. This means:
- the controls in the document must actually be implemented
- if the method changes, the SWMS must be updated before the change takes effect
- workers must be able to follow the SWMS, which requires they understand it
HRCW must not start without a SWMS
The sequencing matters. A SWMS must be prepared and workers must be consulted before HRCW begins. It is not acceptable to start the job and then produce the document later. If the work has already started without a SWMS, the correct course of action is to stop the work, prepare and review a compliant SWMS, brief the workers, and then resume.
Starting work before the SWMS is complete removes the whole point of the document, which is to plan the controls before the risk is present.

Frequently asked questions
Can work be stopped if there is no SWMS on site?
Yes. A WHS inspector can issue a prohibition notice that immediately stops the High Risk Construction Work until a compliant SWMS is in place and the risk is managed.
What fines apply for not having a SWMS?
Fines vary by jurisdiction but can reach hundreds of thousands of dollars for a PCBU and tens of thousands for an individual. Serious breaches involving a risk of death or serious injury carry the highest penalties.
Does a SWMS need to be physically on site?
Yes. The SWMS must be readily accessible to workers and available for inspection. Having a document stored somewhere off site and inaccessible to the crew does not satisfy the legal requirement.
Is it a breach if a SWMS exists but is not being followed?
Yes. A SWMS that exists on paper but is not being implemented is still a breach. The PCBU and workers must follow the controls set out in the SWMS while the work is being carried out.
