Quick answer: A sole trader in Australia who is a PCBU typically needs a WHS policy, SWMS for any high risk construction work, Safety Data Sheets for any hazardous chemicals used, plant and tool maintenance records, current licences and tickets for the work performed, and appropriate insurances including public liability and personal accident cover. The exact documents required depend on your trade, the nature of your work, and what head contractors ask for when you work as a subcontractor.
Last reviewed: 12 June 2026
Being a sole trader does not mean being exempt from WHS obligations. Under the model Work Health and Safety Act 2011, a sole trader who conducts a business or undertaking is a person conducting a business or undertaking (PCBU) — and PCBUs carry a primary duty of care to ensure health and safety, so far as is reasonably practicable. That duty applies even when you work alone, and it brings with it a practical need for certain documents.
This guide sets out the realistic minimum set of WHS documents a sole trader needs, explains the purpose of each, and covers what you are likely to be asked to produce when working as a subcontractor for a head contractor or principal contractor.
Note: WHS legislation in Australia is based on the model Work Health and Safety Act 2011, but each state and territory has its own laws and regulators. Always check the requirements in your jurisdiction.

SWMS for high risk construction work
If you carry out high risk construction work (HRCW), you must have a SWMS in place before that work commences — regardless of whether you have employees. Working alone does not reduce this obligation, and in some cases working without another person nearby increases the risk.
High risk construction work includes activities such as:
- Work at heights greater than 2 metres
- Work in or around confined spaces
- Excavation deeper than 1.5 metres
- Demolition of load-bearing structures
- Work near energised electrical installations or services
- Work involving pressurised gas distribution mains or piping
- Work in or near water or other liquids involving a risk of drowning
- Work in areas with artificial extremes of temperature
A SWMS must identify the HRCW activity, the hazards associated with it, and the risk controls that will be applied. It should be accessible at the worksite and reviewed if conditions change or a new project begins. Principal contractors will commonly ask to see your SWMS before you start work.
For a detailed breakdown of when and why a SWMS is required, see our guide: Does a sole trader need a SWMS?
WHS policy
A WHS policy is a brief, written statement of your commitment to health and safety. As a sole trader PCBU, you are expected to have one — and it is one of the first things a head contractor, principal contractor, or client will ask for.
A sole trader WHS policy does not need to be lengthy. It should cover:
- Your commitment to managing health and safety risks in your work
- Your key duties as a PCBU, including self-care obligations
- How you will identify and manage hazards
- How you will report and respond to incidents
Even a one-page policy is sufficient, provided it is genuine, current, and signed by you. Review it at least annually or when your work activities change significantly.
Safety Data Sheets and chemical management
If you use or store any hazardous chemicals in the course of your work — whether that is two-pack coatings, adhesives, solvents, cleaning products, or any other substance that is classified as hazardous — you are required to:
- Obtain and keep a current Safety Data Sheet (SDS) for each hazardous chemical
- Make the SDS accessible at the location where the chemical is used or stored
- Maintain a chemical register listing the hazardous chemicals you have on hand
An SDS is provided by the manufacturer or supplier of the chemical and must conform to the GHS (Globally Harmonised System of Classification and Labelling of Chemicals) format. SDS documents expire after five years, so check that yours are current.
For most sole traders, the chemical management obligations are relatively straightforward — a simple register and a folder of SDS documents (physical or digital) is usually sufficient.
Plant and tool maintenance records
As a PCBU, you are responsible for ensuring that the plant and equipment you use is safe. This means conducting regular inspections, carrying out or arranging maintenance, and keeping records that demonstrate your equipment is in a safe condition.
Plant and tool maintenance records for a sole trader typically cover:
- Power tools and hand tools: Regular inspection for damage, worn guards, faulty cords or switches
- Portable electrical equipment: Electrical testing and tagging in accordance with the relevant Australian Standard (AS/NZS 3760) — required in many states and commonly expected on construction sites
- Ladders and access equipment: Pre-use inspection and periodic formal inspection records
- Vehicles and trailers: Registration, roadworthy status, and any regular servicing records relevant to your work
- Specialised plant: Any larger plant items such as compressors, generators, or elevated work platforms — inspection and service records, along with operator competency
You do not need a complex maintenance management system. A simple log — whether on paper or in a spreadsheet — that records the date, item inspected or serviced, the outcome, and any action taken is sufficient for most sole traders.
Licences, tickets, and certificates
Certain types of work require a formal licence or certificate of competency before you can legally perform them. Common examples for trades people and sole traders include:
- High risk work licences (HRW licences): Required for activities such as scaffold erection, dogging, rigging, crane and hoist operation, and forklift operation
- Electrical work licence: Required for any licensed electrical work — requirements vary by state and territory
- Plumbing and gasfitting licence: Required for licensed plumbing, draining, and gasfitting work
- Construction induction (White Card): Required for anyone carrying out construction work
- Asbestos removal licence: Required for Class A or Class B asbestos removal work
- Demolition licence: Required for certain demolition activities depending on jurisdiction
Keep physical or digital copies of all current licences accessible. If a licence is due for renewal, allow enough time to complete renewal before it lapses — working on an expired licence can have serious legal consequences and may void your insurance.
Insurances
Insurances are not strictly WHS documents, but they are closely linked and are routinely requested alongside your safety documents when you work as a subcontractor.
Public liability insurance
Public liability insurance protects you against claims for third-party personal injury or property damage arising from your work. Most head contractors will require a current certificate of currency before allowing you on site, and many contracts specify a minimum cover amount — commonly $5 million or $10 million. Even when working directly for a homeowner or small business, public liability insurance is a fundamental risk management measure.
Personal accident and income protection insurance
If you are injured at work and cannot earn income, workers compensation does not apply to you as a sole trader — you are generally not covered by the workers compensation scheme in the same way an employee is. Personal accident insurance or income protection insurance fills this gap by providing a benefit if you are unable to work due to injury or illness. This is particularly important for sole traders who have no sick leave entitlements and whose income depends entirely on their capacity to work.
Workers compensation insurance
If you engage workers — including casuals or labour hire — workers compensation insurance is compulsory in all states and territories. The rules on whether an owner-operator needs workers compensation can be complex and vary by jurisdiction, so check with your state insurer or regulator if you are unsure.
What head contractors ask for from sole-trader subbies
When you work as a subcontractor for a principal contractor or larger head contractor, you will typically be asked to provide documentation before you start work and as part of an ongoing subcontractor management process. Common requirements include:
- SWMS for each HRCW activity you will perform on site
- WHS policy — a current, signed copy
- Public liability insurance certificate of currency — often with a minimum cover level specified in your contract
- Relevant licences and tickets — especially for licensed work or HRW activities
- White card (construction induction)
- ABN and contractor details
- Completed site induction form before commencing work
Some larger principal contractors run a formal pre-qualification process, where you complete a WHS questionnaire or submit your policy and key procedures before being approved to work for them. Having your documents in order before you start tendering or quoting work means you are not scrambling to pull things together at the last minute.
Example scenario
Consider a sole trader carpenter in New South Wales who works mainly as a subcontractor on residential construction projects. On a typical job, this sole trader would hold:
- A WHS policy — a brief, signed document covering their safety commitment and key obligations as a PCBU
- SWMS for work at heights (including working on roofs and elevated decking) and any other HRCW activities that arise on the project
- SDS documents for the adhesives, solvents, and timber treatments used on site, kept in a folder in their work vehicle alongside a simple chemical register
- Plant and tool maintenance records — a log tracking inspection of power tools, test-and-tag records for portable electrical equipment, and ladder inspection records
- A current White Card, ABN registration, and any relevant certifications
- A current public liability insurance certificate of currency at $20 million — provided to the head contractor as part of their subcontractor onboarding
- Personal accident insurance providing weekly benefits if they are unable to work due to injury
This sole trader would also keep an incident record to document any injuries or near misses, and would update their SWMS before starting a new project or if the scope of their work changes significantly.
Sole trader documents versus small business documents
Sole traders who begin taking on employees or regularly engaging workers move from sole-trader obligations into the broader set of obligations that apply to small businesses with workers. Additional documents — including a training register, return-to-work program (in most states), and a more formal WHS management system — become necessary at that point.

Frequently asked questions
Is a sole trader a PCBU under the WHS Act?
Yes. A sole trader who conducts a business or undertaking is a PCBU under the model Work Health and Safety Act 2011, regardless of whether they have employees. As a PCBU, a sole trader has a primary duty of care to ensure the health and safety of themselves and any other people who may be affected by their work, so far as is reasonably practicable. This means WHS obligations apply even when you work entirely alone.
Does a sole trader need a SWMS if they work alone?
Yes, if the work involves high risk construction work (HRCW). The obligation to have a SWMS in place before commencing HRCW applies regardless of whether you have employees or work entirely by yourself. Working alone can actually increase the risk associated with some HRCW activities, which makes having a SWMS even more important. See our guide on whether a sole trader needs a SWMS for more detail.
What documents will a head contractor ask for when I work as a subbie?
Most head contractors will ask for your SWMS for any HRCW activities, a current certificate of currency for public liability insurance, your relevant licences or high risk work licences, a completed induction form, and often your ABN and a copy of your WHS policy. Some principal contractors also run a formal subcontractor pre-qualification process that requires you to complete a safety questionnaire or submit your policy and procedures before mobilising. Having your documents ready in advance avoids delays.
How often does a sole trader need to review their WHS documents?
At a minimum, WHS documents should be reviewed annually or whenever there is a significant change to your work activities, equipment, chemicals used, or applicable legislation. SWMS should be reviewed before each new job or if the nature of the work changes materially. Plant and tool maintenance records should be updated every time an inspection, service, or repair occurs. Keeping a review date on each document helps demonstrate that your safety management is active and not just a set-and-forget exercise.
