Mutual Recognition Across States

Your trade licence is only valid in the state that issued it — until you are recognised in the next one. Mutual recognition lets most licensed tradies register interstate on the back of their home licence, but it is not automatic for every trade, and working before you are recognised is treated as working unlicensed. Here is how it actually works, the short-term-job options, and the traps. (Guidance, not legal advice.)‍‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‍

The Mutual Recognition Act 1992 (classic MR)

Under the MRA, holding an occupational licence in one state entitles you to be registered for the equivalent occupation in another, generally on no more restrictive terms. But the key word is apply: it is a right to apply, not an automatic licence. You must:

be substantively registered at home (current, not suspended or prohibited);
lodge an MR application with the destination regulator, with a certified copy of your home licence, ID, a statutory declaration and your disciplinary history;
pay a fee (low hundreds for contractor-level — e.g. a NSW trade contractor sits around $300/year);
wait — some regulators issue an interim authority on lodgement, others require the full grant before you work. Timing is a few days to several weeks, not instant.

Most trade occupational licences are covered, but MR does not override local OH&S, environmental or consumer-law obligations, and separate national regimes (aviation, maritime, some health/security) sit outside it.

Automatic Mutual Recognition (AMR)

AMR goes further: an eligible worker licensed in one state is automatically recognised in another without a second licence — if both jurisdictions have opted in for that occupation, you notify the second state, and you meet local conditions (insurance, fit-and-proper). The catches:

Not every state, trade or class is under AMR. Notably, Queensland is not in AMR for electrical or gas work, and AMR does not yet cover builders in Tasmania.
AMR does not override bans, suspensions or disciplinary conditions.
It covers the licensing only — you still comply with the destination's building codes, WHS and consumer guarantees, and should carry evidence of your home licence and AMR notification on site.

So the rule of thumb: in some states AMR may cover you; otherwise lodge a formal MR application before working.

Short-term interstate jobs

Three models:

Full MR registration — the safest and most common for electrical, plumbing and builder-contractor work. Apply even for a few weeks. Example: a NSW plumbing sole trader on a 3-month VIC project lodges an MR application with the VIC plumbing regulator (on the NSW licence) before starting, and waits for the interim or full licence. Skip it and you are unlicensed in VIC — prosecution, voided insurance.
AMR notification — if both states and your class are covered, you rely on your home licence and notify the second state. Example: a QLD-licensed carpenter working in NSW under AMR checks the NSW guidance, completes the notification, and shows the QLD licence on invoices. Confirm your specific class is AMR-eligible — do not assume.
Job-specific permits — niche only (environmental/hazardous-activity permits layered on a base licence, or subbie work under a principal contractor's local licence). There is no quick "permit per job" workaround for core licensed trade work.

The cross-state traps

"My licence works everywhere." It does not — it is only valid in the issuing state until you are recognised.
Not realising MR needs an application. It is a shortcut in the application process, not a substitute for it — you still submit, pay and (for non-AMR) wait.
Mis-matching licence classes. Categories do not line up perfectly — a "builder low-rise" may split differently, and gas, backflow or solar may need an extra destination endorsement. Ask both "do I have a licence?" and "does it cover the exact work I will do in that state?"
Ignoring local add-ons. States cannot duplicate core licensing but can require local insurance, home-warranty enrolment and the licence in the correct legal entity's name.

Enforcement across borders

Working without the correct state licence is a criminal or civil offence, not a technicality. Regulators can fine you, prosecute, order the work stopped or rectified by a licensed person at your cost, record a disciplinary finding that follows you back to your home licence, and void your insurance and contract rights. Regulators cooperate across borders — "but I am licensed back home" is not a defence.

Common mistakes

Starting work interstate before the MR application is granted (or assuming AMR when QLD electrical/gas or TAS builders are not covered).
Treating AMR as covering codes and WHS — it only covers licensing.
Working outside the recognised scope after a class mismatch.
Not enrolling in the destination's home-warranty scheme or licensing the right entity.
