Do you need a carpentry licence in Australia? State-by-state 2026 guide
Unlike electrical and plumbing, carpentry licensing in Australia varies hugely by state, and depends on whether you're a sub-contractor or a builder.
Carpentry is the odd one out in Australian trade licensing. Unlike electrical and most plumbing, you can do some carpentry work without a licence, but the threshold above which you need one varies wildly between states. Get it wrong and your work isn’t covered by insurance, your client can refuse to pay, and you’re not eligible for Home Building Compensation.
The short version
| State | Threshold (work value above which licence required) | Licence type | Regulator |
|---|---|---|---|
| NSW | $5,000 (including labour + materials) | Contractor / endorsed contractor | NSW Fair Trading |
| VIC | All structural building work | Registered Building Practitioner | VBA |
| QLD | $3,300 (incl GST) | Contractor licence | QBCC |
| WA | $20,000+ residential / $40,000+ commercial | Registered builder for structural; carpenter card otherwise | Building & Energy WA |
| SA | $12,000 | Building work contractor | CBS |
| TAS | $20,000 | Building services licence | CBOS |
| NT | Most building work | Building practitioner | Building Practitioners Board NT |
| ACT | Defined construction work | Construction occupations licence | Access Canberra |
Above these thresholds: licence required. Below: usually not, but structural work (frames, load-bearing walls, decks attached to a dwelling) often requires one regardless of value.
What carpentry work commonly needs a licence
Across all states, these almost always require licensing:
- Structural framing of a dwelling
- Roofing structural work
- Decks attached to a dwelling above a certain height (varies, usually 1m)
- Pergolas attached to a dwelling above a certain size
- Internal load-bearing walls
- Anything requiring council approval (DA-required work)
What’s usually exempt (still verify):
- Garden sheds under a defined size
- Free-standing pergolas under defined size
- Furniture-making and joinery (not attached to the structure)
- Decking under defined height (varies. NSW: 600mm)
- Minor repair work below the threshold
NSW
NSW Fair Trading issues building/trade licences. Two main types:
- Trade contractor licence, lets you sub-contract carpentry work
- Endorsed contractor licence, same plus ability to contract directly with home-owners
Cert III + 2 years post-apprenticeship experience + course in business management gets you the contractor licence. NSW requires Home Building Compensation insurance for work over $20,000.
VIC
The Victorian Building Authority requires registration as a Building Practitioner for structural building work. Categories include:
- Domestic Builder (Unlimited / Limited / Manager)
- Domestic Builder. Carpentry (a specific class)
To register: Cert III + Cert IV in Building & Construction + qualifying experience + practitioner exam. The bar in VIC is higher than NSW, and the VBA enforces strictly post-Lacrosse-tower-fire.
QLD
QBCC is strict and runs the lowest threshold in Australia ($3,300). Three classes are relevant for carpentry:
- Trade contractor. Carpentry
- Builder. Open
- Builder. Low Rise
QLD also requires QBCC’s Home Warranty Insurance on residential work over $3,300, clients can refuse to pay if you don’t have it.
WA
WA’s Building Services Board administers builder registration. Carpenters working as sub-contractors on someone else’s licensed jobs can hold a Trade Contractor Authorisation rather than full builder registration. Threshold is higher than the east coast, $20K residential.
SA, TAS, NT, ACT
Lighter regimes but verify:
- SA, $12K threshold; CBS Building Work Contractor licence
- TAS, $20K threshold; CBOS Building Services Provider
- NT. Building Practitioners Board administers
- ACT. Access Canberra, construction occupations regime
Becoming a sole-trader carpenter, the checklist
- Complete Cert III in Carpentry
- Finish apprenticeship (typically 4 years)
- Get post-apprenticeship experience, typically 2 years on the tools as a qualified tradesperson
- Complete Cert IV in Building & Construction (or state-specific equivalent)
- Apply for the state contractor licence
- Take out:
- Public liability insurance ($10M is standard)
- Workers’ comp if you have employees
- Home warranty/compensation insurance per state requirement
- Tool insurance
- Set up ABN and business structure (sole trader vs Pty Ltd)
- Register for GST if turnover will be over $75K
Hiring a carpenter, what to verify
Before signing any contract above the state threshold:
- Ask for the licence number, state issued, and class
- Verify on the regulator’s register, every state has free online search
- Confirm Home Warranty / Compensation insurance is in place
- Check the licence covers structural work if your job involves framing or load-bearing
- Get the contract in writing, required by law in most states for residential work over the threshold
The licence number isn’t the carpenter’s ABN. They’re separate. You need both for legitimate residential work.
Licensing rules change. Always confirm your state’s current requirements with the regulator before paying any fee or hiring any tradesperson.
Frequently asked questions
Do I need a licence to do carpentry work in Australia?
It depends on the state and the type of work. NSW and QLD require a contractor or trade licence above a value threshold ($5,000 in NSW, $3,300 in QLD). VIC requires registration as a building practitioner for structural carpentry. WA and ACT have similar contractor frameworks. SA, TAS, and NT have lighter regimes.
Is a Certificate III in Carpentry enough to start working?
It qualifies you to work as a tradesperson under an employer, but for sole-trader contractor work above the state threshold, you also need a contractor licence (NSW, QLD, VIC, WA) or registration.
How long does it take to become a fully qualified carpenter?
Four-year apprenticeship plus Certificate III in Carpentry. To start your own business, add the time to get the contractor licence, typically a further short course plus business management requirements.
