When is a SWMS Required in Australia?

The question "when is a SWMS required?" has a clear legal answer: a Safe Work Method Statement must be prepared before any high-risk construction work commences. Not during. Not after. Before. This is not a best-practice recommendation — it is a legal obligation under the Work Health and Safety Regulation, and breaching it can result in fines exceeding $500,000 for a body corporate and personal liability for officers and directors.

This guide explains exactly when a SWMS is required, who must prepare it, what happens if you do not have one, and the specific activities that trigger the requirement.

The obligation to prepare a SWMS comes from the Work Health and Safety (WHS) Regulation — specifically sections 299 to 303 in jurisdictions that have adopted the model WHS laws (NSW, QLD, WA, SA, TAS, ACT, NT). Victoria operates under separate Occupational Health and Safety (OHS) legislation but has equivalent requirements.

Under WHS Regulation s299, a person conducting a business or undertaking (PCBU) must ensure that a SWMS is prepared before high-risk construction work (HRCW) commences. The SWMS must be prepared in consultation with workers who will carry out the HRCW. Work must not commence until the SWMS is in place and all workers have been briefed.

Under WHS Regulation s300, the principal contractor for a construction project has additional obligations. They must ensure that a SWMS is prepared for all HRCW to be carried out at the workplace, and they must not allow HRCW to commence unless a compliant SWMS is in place. The principal contractor can request copies of any SWMS from subcontractors.

Under WHS Regulation s301, a SWMS must be kept and be readily accessible to workers while the HRCW is being carried out. If a notifiable incident occurs in connection with the HRCW, the SWMS must be retained for at least two years from the date of the incident.

The legislation is deliberately strict about timing. A SWMS prepared after work has started — even if it is technically compliant in content — does not satisfy the legal requirement. The purpose of a SWMS is to force everyone to stop, think, and plan before the high-risk work begins. Preparing it retrospectively defeats that purpose entirely.

A SWMS is required specifically for high-risk construction work. The WHS Regulation defines 18 categories of HRCW. If your work involves any of these activities, a SWMS is legally required before you start.

**Falls and heights.** Work involving a risk of a person falling more than 2 metres. This is the most commonly triggered HRCW category and includes work on roofs, scaffolding, elevated platforms, ladders (where the fall distance exceeds 2m), and any edge or opening where a fall is possible. In practice, this covers almost all roofing work, upper-level construction, facade work, and elevated maintenance. Victoria's OHS legislation uses different thresholds for some work — consult WorkSafe Victoria for current requirements.

**Telecommunications.** Work on a telecommunication tower. All work on towers or masts used for telecommunications, regardless of height or complexity.

**Demolition.** Demolition of a load-bearing structure. Any demolition that removes or compromises structural elements — walls, columns, beams, floors, or roofs that support other building components. This includes partial demolition (strip-outs that affect structure) and full demolition.

**Asbestos.** Work involving the disturbance or removal of asbestos. Any activity that may release asbestos fibres, including removal, encapsulation, drilling through asbestos-containing materials, or maintenance that risks fibre release. Note that asbestos removal also has separate licensing requirements — Class A for friable asbestos, Class B for non-friable asbestos exceeding 10 square metres.

**Confined spaces.** Work in a confined space. A confined space is any enclosed or partially enclosed space not designed for human occupancy, with restricted entry and exit, and a risk of hazardous atmosphere, engulfment, or entrapment. Examples include tanks, silos, pits, sewers, tunnels, ducts, and some roof voids.

**Tilt-up and precast.** Work involving tilt-up or precast concrete elements. Erection, positioning, bracing, or securing of tilt-up panels or precast concrete components. This is one of the highest-risk construction activities due to the potential for panel collapse during erection.

**Pressurised gas.** Work on or near pressurised gas distribution mains or piping. Work in proximity to gas mains, high-pressure gas piping, or gas distribution infrastructure.

**Chemical and fuel lines.** Work on or near chemical, fuel, or refrigerant lines. Work near pipelines containing hazardous chemicals, fuels, or pressurised refrigerants.

**Energised electrical.** Work on or near energised electrical installations or services. Electrical work on live systems, or work performed near energised conductors where there is a risk of contact. This includes work near overhead power lines (even if the worker is not doing electrical work) and underground electrical cables.

**Powered mobile plant.** Work in areas with movement of powered mobile plant. Work in areas where excavators, forklifts, cranes, trucks, bobcats, or other powered mobile plant is operating. This is triggered even if the worker is not operating the plant — the hazard is the interaction between plant and people.

**Extreme temperatures.** Work in areas with artificial extremes of temperature. Work in freezer rooms, furnace environments, smelters, or other artificially heated or cooled environments that create health risks to workers.

**Drowning risk.** Work in or near water where there is a risk of drowning. Work near rivers, dams, tanks, swimming pools under construction, marine environments, or any body of water where a worker could fall in and be at risk.

**Diving.** Work involving diving. All commercial diving operations regardless of depth or duration.

**Underground work.** Work in tunnels, shafts, or trenches deeper than 1.5 metres. Excavation, trenching, tunnel boring, shaft sinking, or any underground work where the depth exceeds 1.5 metres or where there is a risk of ground collapse.

**Explosives.** Work involving the use of explosives. All blasting, explosive demolition, and any work that uses explosives as part of the construction process.

**Roads and railways.** Work on or near roads or railways in use. Work performed adjacent to live traffic or within operational rail corridors, including road construction, bridge work, and infrastructure maintenance.

**Airfall and rockfall.** Work at a workplace where there is a risk of airfall or rockfall. Work near cliffs, cuttings, quarry faces, or unstable ground where rocks, earth, or debris could fall on workers.

**Structural alterations.** Work involving structural alterations requiring temporary support. Modifications to existing structures that require propping, shoring, or temporary bracing to prevent collapse — such as removing walls, cutting new openings, or altering load paths.

The PCBU who will carry out the HRCW is responsible for ensuring the SWMS is prepared. In most cases this is the subcontractor or contractor performing the specific high-risk work.

The principal contractor has an oversight obligation — they must ensure that every subcontractor performing HRCW on their project has a compliant SWMS in place before the work starts. Many principal contractors will not allow a subcontractor on site without first reviewing and accepting their SWMS.

The SWMS must be developed in consultation with the workers who will perform the HRCW. This is a specific legislative requirement, not a suggestion. A SWMS prepared by a safety consultant who has never spoken to the workers performing the work is not compliant, no matter how thorough it is.

If a health and safety representative (HSR) has been elected for the workplace, they have the right to be consulted during the preparation of the SWMS and can request a review at any time.

The SWMS must be prepared **before** the HRCW commences. The legislation is clear on this point — the SWMS must exist before the first worker begins the high-risk activity.

In practice, this means the SWMS should be prepared as part of the planning and preparation phase of the project, not on the morning the work is due to start. For subcontractors, the SWMS is typically prepared as part of the tender or pre-start process and provided to the principal contractor for review before mobilisation.

If conditions change during the work — for example, the scope changes, a new hazard is identified, another trade begins working in the same area, or weather conditions deteriorate — the SWMS must be reviewed and revised before work continues. The revised SWMS must be communicated to all workers.

The penalties for performing HRCW without a compliant SWMS are significant and should not be underestimated.

Under the model WHS laws, a PCBU that fails to ensure a SWMS is in place for HRCW commits a Category 2 offence if the failure exposes a worker to a risk of death, serious injury, or serious illness. Maximum penalties for a Category 2 offence are $1,500,000 for a body corporate and $300,000 for an individual (including officers and directors).

Even without an incident, the failure to have a SWMS is a breach of WHS Regulation s299 and can result in an improvement notice, a prohibition notice (which stops work immediately), or an infringement notice (on-the-spot fine).

Beyond regulatory penalties, the absence of a SWMS significantly weakens a PCBU's defence in any civil litigation arising from a workplace injury. A court will ask what safety measures were in place — and the absence of the legally required document is powerful evidence of negligence.

Insurance implications are equally serious. Many workers' compensation and public liability insurers require evidence of SWMS compliance. A claim arising from HRCW performed without a SWMS may be challenged by the insurer, potentially leaving the PCBU to bear the cost.

Strictly speaking, no. The WHS Regulation requirement for a SWMS applies specifically to the 18 HRCW categories, which are defined within the context of construction work. Non-construction activities — even hazardous ones — do not legally require a SWMS.

However, many non-construction employers prepare SWMS-style documents for high-risk activities as a best-practice measure. Manufacturing, mining, oil and gas, and utilities industries commonly use SWMS or equivalent documents for tasks like working at heights, confined space entry, and hot work — even though these are not strictly "construction work" under the WHS Regulation.

For non-construction high-risk tasks, a Job Safety Analysis (JSA) is the more common document. It serves a similar purpose — identifying hazards and controls for a specific task — without the additional compliance requirements of a SWMS. See our comparison: [SWMS vs JSA — What's the Difference?](/swms-vs-jsa).

A SWMS is a living document. It must be reviewed and, where necessary, revised whenever any of the following occur.

The work conditions change — different area of the site, different weather, different equipment, another trade begins working in the same zone. A new hazard is identified that was not addressed in the original SWMS. A notifiable incident occurs in connection with the HRCW covered by the SWMS. A health and safety representative requests a review. At regular intervals determined by the PCBU — many organisations review weekly or at the start of each new work phase.

When the SWMS is revised, all previous versions must be retained. All workers must be re-briefed on the changes and sign the updated document before work continues.

Preparing a SWMS from scratch is time-consuming and carries the risk of missing critical hazards specific to your trade.

### Is a SWMS required for residential construction?

Yes, if the work involves any of the 18 HRCW categories. The trigger is the activity, not the project type. Working at heights above 2 metres on a residential roof requires a SWMS just as it would on a commercial building.

### Is a SWMS required for maintenance work?

If the maintenance work involves one of the 18 HRCW categories — for example, working at heights, confined space entry, or work on energised electrical installations — then yes, a SWMS is required. Routine maintenance that does not involve HRCW does not require a SWMS, though a JSA is recommended.

### Does the principal contractor need to prepare the SWMS?

The principal contractor does not typically prepare the SWMS — the subcontractor performing the HRCW prepares it. However, the principal contractor must ensure that a compliant SWMS is in place before allowing HRCW to commence, and can require revisions if the SWMS is inadequate.

### Can a SWMS be prepared by someone other than the contractor doing the work?

The SWMS can be prepared by anyone, but it must be developed in consultation with the workers who will carry out the HRCW. A SWMS prepared by a safety consultant without worker input is not compliant. In practice, the contractor usually prepares the SWMS with input from their workers.

### What if I'm working in multiple states?

If your work is in a state that has adopted the model WHS laws (NSW, QLD, WA, SA, TAS, ACT, NT), the requirements are essentially the same. Victoria uses separate OHS legislation with equivalent but not identical requirements. Check with the relevant state regulator for any jurisdictional differences.
