SafeWork inspector: powers and how to handle a visit

A WHS inspector (SafeWork or WorkSafe) can enter a site without notice and issue improvement or prohibition notices. How a builder should handle a visit.

A SafeWork inspector is an authorised officer of the work health and safety regulator with broad legal powers to enter a workplace, investigate, and enforce the safety laws. “SafeWork inspector” is the common name, but the regulator and the Act differ by state, and a building site is squarely in their jurisdiction.

Who they actually are (it varies by state)

The role is the same; the badge is not:

  • Model WHS Act states (NSW, QLD, SA, WA, TAS, ACT, NT, and the Commonwealth): inspectors from SafeWork NSW, Workplace Health and Safety Queensland, SafeWork SA, WorkSafe WA, and the rest, under each state’s Work Health and Safety Act.
  • Victoria: a different regime. Victoria runs the Occupational Health and Safety Act 2004, and the regulator is WorkSafe Victoria with OHS inspectors (verified 2026-05-25).

The powers below are materially similar across both regimes.

What an inspector can do

Once on site, an inspector can:

  • Enter without notice, at any time the work is happening (or when they reasonably believe there is an immediate risk). They do not need an appointment.
  • Inspect, measure, photograph, and take samples of the work, plant, and substances.
  • Examine and copy documents, your SWMS, SDS, induction and training records, plant registrations, incident records.
  • Question people, including interviewing workers, and require a person’s name and address.
  • Require reasonable help to exercise their powers, and seize anything as evidence.

They cannot enter a part of a place used as a residence without the occupier’s consent or a search warrant, which matters on a knock-down-rebuild or an occupied renovation.

The notices they can issue

  • Improvement notice: fix a contravention by a stated date.
  • Prohibition notice: stop the activity immediately because it involves a serious risk, and do not resume until the risk is fixed and (where required) the inspector clears it.
  • Non-disturbance notice (WHS Act states): leave a site or thing undisturbed, typically after an incident.
  • Penalty / infringement notices: an on-the-spot fine for certain breaches. The regulator can also prosecute.

When a builder meets one

Inspectors turn up after a notifiable incident (which you are legally required to report and the site preserved), a worker or neighbour complaint, or a targeted blitz program (falls from height, asbestos, silica, traffic management).

For a builder

  • Do not obstruct. Hindering or obstructing an inspector is itself an offence. Be cooperative and professional; you can ask to see their identity card.
  • A prohibition notice means stop now. That activity halts until the risk is controlled. An improvement notice gives you a deadline; diarise it and fix it.
  • Have your WHS paperwork in order. SWMS, SDS, inductions, and plant records are exactly what gets requested. A tidy, current set turns a visit into a short one.
  • After a notifiable incident, preserve the site. Do not disturb the scene (beyond making it safe or aiding the injured) until an inspector or the regulator releases it.
  • Get advice on serious notices. A prohibition notice or prosecution exposure is worth a call to your adviser or insurer before you respond.
