How to Become a Gasfitter in Australia (2026 Apprenticeship Guide)

Gasfitting is one of the most tightly regulated trades in the country — and for good reason, because gas is unforgiving of mistakes. If you want to install and service gas appliances and pipework legally, here’s the plain-English version of how you get qualified and licensed.

Short version: Gasfitting sits within the plumbing trade. You do a plumbing apprenticeship, complete the gasfitting units of your Certificate III, then get a gasfitting licence from your state’s plumbing and gas regulator. Gas work is licensed in every state — there’s no legal way around it.

What the job actually involves

A gasfitter installs, alters, services and repairs gas pipework and appliances — running gas lines, connecting hot water systems, cooktops, heaters, commercial kitchen equipment and industrial plant, testing for leaks, and commissioning appliances so they burn safely. You work with natural gas and LPG, indoors and out, in homes, businesses and industry.

Because gas can leak, ignite or produce carbon monoxide, the work is precise and compliance-heavy. You need to understand pressures, combustion, ventilation and the standards, and you’re legally responsible for the safety of what you install. Most gasfitters are also plumbers, since the two trades overlap heavily and are trained together.

The trade has real breadth. Domestic gasfitters connect hot water units, cooktops and heaters in homes; commercial gasfitters handle restaurant kitchens, laundries and larger appliances; and industrial gasfitters work on plant, boilers and process gas. As you gain experience you can specialise, move into servicing and diagnostics, take on compliance and certification work, or run your own gasfitting business. Because the trade is licensed and safety-critical, qualified gasfitters tend to hold their value well over a career.

The apprenticeship pathway

Gasfitting is learned as part of the plumbing trade. You complete an Australian Apprenticeship — a paid job with a licensed plumber or gasfitter plus structured training through TAFE or another RTO. The core qualification is the Certificate III in Plumbing, which includes gasfitting units, and it typically takes around four years.

Some workers go on to add further gas-specific qualifications for advanced or specialised gas work. But the foundation is the plumbing apprenticeship, with gasfitting built into it.

How to get started

1. Aim to finish Year 10 or above, with solid maths — the trade uses measurement, pressure and calculation constantly.
2. Get your driver’s licence. You’ll travel between jobs with tools and materials.
3. Find a plumbing apprenticeship with an employer who does gas work, and register with the Australian Apprenticeship Support Network at apprenticeships.gov.au.
4. Sign your training contract with your employer and RTO so your apprenticeship is registered.
5. Complete your Certificate III in Plumbing, making sure you do the gasfitting units.
6. Apply for your gasfitting licence or registration through your state plumbing and gas regulator once you qualify.
7. Get your white card for construction sites.

Licensing and registration

This is where gasfitting is strict: gas work is licensed in every state and territory, and you must hold the right licence or registration to carry it out. The licence is issued by your state’s plumbing and gasfitting regulator, and the classes and names differ by state — but the principle is the same everywhere. Doing gas work without a licence is illegal and dangerous.

You typically move from an apprentice, to a licensed tradesperson working under supervision or in your own right, and eventually you can seek higher-level authorisations that let you certify your own work and supervise others. Licences must be kept current and renewed, and some states require compliance certificates for gas work you complete. Always confirm the exact classes and requirements with your state regulator — they’re not identical across the country.

Pay and the money side

As a plumbing and gasfitting apprentice, you’re paid under an award, starting at a percentage of the qualified rate and rising each year until you reach the full trade rate on completion. Adult apprentices usually start higher. Once licensed, gasfitters — especially those doing commercial and industrial gas — are well paid because the work is specialised and carries legal responsibility.

Don’t rely on a quoted number that goes stale — check your exact rate for your award and year using the Fair Work Pay and Conditions Tool at calculate.fairwork.gov.au. For apprentice support payments and help with training costs, start at apprenticeships.gov.au and servicesaustralia.gov.au. For tax, ABN and super questions, go to the ATO.

The earning picture usually improves after you’re licensed. Higher-level gas authorisations, commercial and industrial work, on-call servicing and the ability to certify your own jobs all push your value up. Plenty of gasfitters eventually run their own business — but before you do, make sure you understand your licensing, insurance and tax responsibilities, because certifying gas work in your own name carries real accountability.

FAQ

Is a gasfitter the same as a plumber?

They’re closely linked. Gasfitting is a specialisation trained within the plumbing trade, and most gasfitters are qualified plumbers too. Your Certificate III in Plumbing includes the gasfitting units, and gas work is then separately licensed.

Do I need a licence to do gas work?

Yes — in every state and territory. Gas work is licensed, and doing it without the right licence is illegal. You apply for your gasfitting licence through your state regulator after you qualify.

How long does it take?

Around four years for the plumbing apprenticeship with gasfitting included. Higher-level gas authorisations come later as you gain experience.

Can I just do a short gas course?

Not to work as a licensed gasfitter. Short courses may cover specific tasks, but the recognised pathway is the plumbing apprenticeship followed by state gas licensing. Confirm the requirements with your state regulator.

Do I need to be good at maths?

Solid, practical maths helps a lot. You’ll size pipework, work with pressures and flow, and follow standards that rely on accurate calculation. You don’t need advanced maths, but you do need to be comfortable and careful with numbers.

Is gasfitting a good career?

Yes — it’s specialised, tightly licensed and in steady demand across housing, commercial and industrial work. Licensed gasfitters generally earn well and can move into running their own business.
