Do gas fitters need a licence in Australia?
Yes. All gas work in every state and territory must be done by a licensed gasfitter. In QLD the licence comes from Resources Safety and Health Queensland, and in WA you need a gasfitting permit from Building and Energy.

Hiring? How to check a licence
- Ask for the licence number and the exact name on the licence.
- Search that number on the official register for your state (links below).
- Check the licence is current, not expired, suspended or cancelled.
- Check the licence class covers your job.
- Make sure the name on the quote or invoice matches the licence holder or business.
- Make sure the licence or permit covers gas, not just water plumbing.
- For LPG in a caravan, boat or car, check the special endorsement or class.
- Ask for the compliance certificate or safety certificate when the job is done.

On ServiceTasker, a business uploads its licence and our team checks it before a licence badge shows on its profile. You see what it holds, never the number or the document.
For businesses: how to get this licence
- Qualify: finish a Certificate III in Gas Fitting or Plumbing with the required gas units (TAS also accepts Certificate III in Mechanical Services plus Certificate IV units).
- Experience: most states want supervised experience. NT asks for 2 years for a general gasfitter licence. WA asks for at least 250 hours of on-the-job training for a Class G permit.
- Documents: ID, a photo, your qualification and results. Some states ask for a police check or a declaration about convictions (WA since 1 July 2025).
- Apply to your state regulator (links below). QLD: RSHQ Portal. WA: Building and Energy gasfitting permit.
- If you will run a business, check if your state also needs a contractor licence.
- Licensed in another state? Automatic mutual recognition (AMR) may let you work under your home-state licence. Notify the regulator before you start. Not every licence class is covered, so check the state page first.
