How to Prepare for a WHS Audit in Your Construction Business

A visit from a WHS inspector is not a routine formality. In construction, where fatalities and serious injuries are more common than in almost any other industry, inspectors take their job seriously — and the consequences of being found non-compliant can include prohibition notices (site shutdown), improvement notices, infringement fines, and in serious cases, prosecution.

The best time to prepare for a WHS audit is before one is triggered. For broader context, see our construction compliance checklist. This guide explains what inspectors look for in construction businesses, what documentation you need to have ready, and how to conduct your own pre-audit review.

What Triggers a WHS Audit?

Construction sites are audited in several circumstances:

Notifiable incident: If a serious injury, illness, or dangerous incident occurs on your site, you must notify the WHS regulator immediately. An inspector will typically attend the scene — this is not technically an audit, but it functions as one.

Complaint: A worker, subcontractor, or member of the public can report a WHS concern to the regulator. All complaints are investigated.

Proactive audit campaign: WHS regulators conduct planned audit programs targeting specific industries or risk types. Construction is almost always on the list, with a focus on common fatal risk categories (falls from height, being struck by plant, being caught in/under plant, electrocution).

Referral from other agencies: Building surveyors, council inspectors, or local government may refer WHS concerns to the regulator.

Who Are the Inspectors?

WHS inspectors are employees of state and territory WHS regulators:

• NSW: SafeWork NSW
• VIC: WorkSafe Victoria
• QLD: Workplace Health and Safety Queensland (WHSQ)
• WA: WorkSafe Western Australia
• SA: SafeWork SA
• TAS: WorkSafe Tasmania
• ACT: WorkSafe ACT
• NT: NT WorkSafe

Inspectors have significant powers under the model WHS Act, including:

• Right to enter any workplace at any time (usually during ordinary business hours, but with power to enter at other times)
• Right to inspect and copy documents
• Right to take samples and conduct tests
• Right to take photographs and recordings
• Right to require persons to answer questions
• Power to issue prohibition notices (immediately stopping dangerous work)
• Power to issue improvement notices (requiring specified action within a set period)
• Power to issue infringement notices (on-the-spot fines)

You cannot refuse a WHS inspector entry to your site. You can, however, have a legal representative present if you wish.

What Inspectors Look For in Construction

1. Fall Prevention

Falls from height are the leading cause of fatalities in Australian construction. Inspectors specifically look for:

• Edge protection on any structure or surface where workers are at risk of falling more than 2 metres
• Scaffolding — is it erected correctly? Is there a handover certificate? Are fall protection measures in place?
• Is the correct type and condition of fall protection equipment in use?
• SWMS for fall-risk work
• Are workers using fall protection equipment correctly?

A common trigger for prohibition notices: Roof work proceeding without adequate edge protection or safety nets.

2. SWMS for High-Risk Work

Inspectors will check whether a SWMS exists for all high-risk construction work on the site, and whether:

• It was prepared before the work commenced
• It is site-specific and task-specific (not generic)
• Workers have reviewed and signed it
• It is accessible on site
• It reflects current work conditions

3. Site Entry and Induction

Inspectors will assess whether there is a site entry and induction process in place:

• Is there a defined site entry point?
• Are all persons entering the site inducted (including visitors)?
• Does the induction cover site hazards, emergency procedures, and site rules?
• Are induction records maintained?

4. High-Risk Licences and Plant Certificates

Inspectors will check that:

• Workers performing high-risk work hold the required high-risk work licences (e.g., scaffolding, rigging, crane operation, forklift, explosive power tools)
• Plant requiring registration (e.g., forklifts, cranes, elevating work platforms) has current plant registration
• Operators of registered plant hold the required licence

Common finding: Unregistered plant in use (often older equipment where registration has lapsed).

5. WHS Management Plan

For notifiable construction work (projects valued above the threshold — check your state's regulations, but typically projects costing over $250,000), the principal contractor must have a WHS management plan for the site. Inspectors will check:

• That the plan exists
• That it covers the required content (site rules, coordination arrangements, emergency procedures)
• That subcontractors have been given access to the plan

6. Subcontractor Management

Inspectors will look at how you're managing subcontractors from a WHS perspective:

• Are subcontractors inducted?
• Do they have SWMS for their high-risk work?
• Are they complying with site rules?
• Do you have a system for monitoring their WHS performance?

7. Hazardous Materials — Asbestos and Silica

Inspectors are increasingly focused on:

• Asbestos: Is there an asbestos register for the site (if applicable)? For demolition or renovation of buildings constructed before 2003, has an asbestos survey been conducted? Is any identified asbestos being managed or removed correctly?
• Silica dust: Are exposure controls in place for work that generates silica dust (cutting engineered stone, concrete, sandstone)? Are dust suppression, water suppression, or LEV controls in use? Is appropriate RPE being worn?

8. First Aid

Is first aid equipment available on site? Is there at least one trained first aider for the number of workers on site? Are emergency services contact details accessible?

9. Worker Consultation

Under the model WHS Act, PCBUs must consult with workers on WHS matters. Inspectors may ask whether workers have been consulted about hazards and controls on the site. Having evidence of toolbox talks and worker participation in safety matters is useful.

Conducting Your Own Pre-Audit Site Review

Before an inspector arrives, run a site inspection against the key areas above. Walk the site and ask:

• Is any work proceeding without adequate fall prevention?
• Does every high-risk work activity have a current SWMS on site?
• Can all workers demonstrate their relevant high-risk licences?
• Is plant registered? Are operators licensed?
• Are workers using required PPE?
• Is the first aid kit fully stocked and accessible?
• Does the site entry record show all workers are inducted?

Document your inspection — a site inspection checklist, signed by the supervisor, with any issues noted and corrective actions taken, is evidence of your proactive WHS management.

What Happens If an Inspector Finds a Problem?

Verbal advice: For minor issues, the inspector may simply advise you on what needs to be done. No formal action.

Improvement notice: A formal notice requiring you to remedy a specific issue within a set timeframe (typically 1 to 8 days). You must comply with the notice by the deadline. Failure to comply is an offence.

Prohibition notice: If a work activity involves an immediate risk to health and safety, the inspector will issue a prohibition notice stopping that work immediately. The work cannot resume until the notice is complied with and cleared. For a busy construction project, a prohibition notice on a critical trade is a significant commercial and safety event.

Infringement notice: On-the-spot fine for specific offences. Fines vary by jurisdiction and offence.

Prosecution: In serious cases — particularly where there has been a fatality or serious injury, or where non-compliance is repeated or deliberate — the regulator will prosecute in court. Category 2 offences (failure to comply with a WHS duty, exposing persons to risk) carry maximum penalties of $1.82 million for corporations under the model Act.

Building a Culture of Ongoing WHS Compliance

Audit readiness is not a one-time preparation exercise — it's a product of an ongoing commitment to WHS compliance. Businesses that sail through WHS audits are the ones that treat site safety as a daily practice: regular site inspections, consistent SWMS use, genuine toolbox talks, and supervisors who actually intervene when they see unsafe behaviour.

The paper trail matters — but the behaviour it's supposed to describe matters more.
