Australia doesn't have one national licensing system for trades — each state and territory runs its own registration and licensing scheme, with its own rules for plumbers, electricians and builders. That's one of the biggest reasons people get caught out: a licence check that's valid in one state doesn't automatically mean the same tradie is compliant in another.
Before you hire anyone through TradieDirectory.com or elsewhere, it's worth spending five minutes confirming their licence is current in the state the job is happening in.
In Victoria, building work and licensed trades are overseen through Consumer Affairs Victoria, with industry bodies like the Master Builders Association of Victoria also maintaining member directories of registered builders. Always ask for a registration number and check it against the relevant public register before work begins.
NSW licensing for trades and home building work is administered by NSW Fair Trading, which runs a searchable public register of licensed tradespeople. The Master Builders Association of NSW is another useful reference point for builders and contractors operating in Sydney and across the state.
Queensland requires most building and trade contractors to be licensed through the Queensland Building and Construction Commission (QBCC), which also publishes a free online licence checker — one of the most straightforward tools of any state for confirming a contractor is legitimate before you sign anything.
If you're not sure which state body applies, Master Builders Australia is the national umbrella body and can usually point you toward the right state association or regulator.
In practice, this comes down to three quick steps: ask for the licence or registration number, search it on the relevant state register, and confirm the name on the licence matches the business you're dealing with. It takes a few minutes and it's the single best protection against unlicensed operators.
