Can you do your own electrical work in Australia?

No. Unlike some countries, Australia does not have a homeowner exemption for fixed wiring. In every state and territory, work on the fixed electrical installation in your home has to be done by a licensed electrician (often through a licensed or registered electrical contractor).

That covers more than people expect. Queensland’s Electrical Safety Office specifically calls out installing a powerpoint and fitting a ceiling fan as jobs that need a sparky. NSW Fair Trading says you need a licence for any electrical wiring work, whatever the cost of the job. The rule generally includes:

• Adding, moving or replacing powerpoints and light switches
• Replacing a light fitting, downlight or ceiling fan that is wired in
• Connecting a hard-wired oven, cooktop, hot water system or air conditioner
• Any work on the switchboard, including adding or replacing safety switches
• Running new cable, even inside a shed or garage

Buying hard-wired fittings at the hardware store is legal. Connecting them yourself is not. This is general information, not legal advice, so check your state regulator’s website for the exact definition of electrical work where you live.

The jobs that don’t touch fixed wiring are fine for anyone:

• Changing a light globe (switch off first and let it cool)
• Plugging in and using appliances, power boards and extension leads
• Resetting a tripped circuit breaker or safety switch
• Pressing the test button on your safety switches
• Replacing the battery in a battery-powered smoke alarm
• Installing plug-in devices like smart plugs and plug-in timers

Take care with jobs next to electrics too. Drilling into a wall or driving screws can hit hidden cables, so use a stud and cable detector and avoid drilling directly above or below powerpoints and switches, where cables usually run.

• NSW: NSW Fair Trading licenses electricians. A licence is needed for any electrical wiring work.
• VIC: Energy Safe Victoria. It says DIY electrical work is illegal, and a registered electrical contractor should issue a Certificate of Electrical Safety for prescribed work.
• QLD: the Electrical Safety Office (part of WorkSafe Queensland). It runs an online licence search so you can check your sparky.
• WA: Building and Energy (Department of Energy, Mines, Industry Regulation and Safety). Electrical installing work must be done by a licensed electrical contractor.
• SA: the Office of the Technical Regulator sets the safety standards, and Consumer and Business Services handles licensing and licence checks.
• TAS: electrical licensing sat with CBOS, whose functions moved to Consumer Affairs Tasmania and Building Standards Tasmania from 1 October 2026.
• ACT: Access Canberra issues electrical licences.
• NT: the Electrical Safety Regulator within NT WorkSafe, which took over licensing when the Electrical Safety Act 2022 started on 1 July 2024.

Penalties are set by each state’s laws and are expressed in penalty units that change over time, so there is no single national figure. They can run into the tens of thousands of dollars for individuals and more for companies. WA’s regulator, for example, has publicised a $45,000 total in fines against one business for unlicensed electrical work.

If someone is hurt or killed because of illegal work, the consequences are far more serious. Check the current maximum penalties with your state regulator rather than relying on figures quoted in old articles.

It can. If a fire or shock is traced back to unlicensed wiring, your insurer may reduce or refuse the claim, because most policies expect work to be done lawfully. Unlicensed work can also turn up when you sell, when a building inspector looks at the switchboard or when an electrician is called in later and finds non-compliant wiring.

When you do pay a sparky, ask for the compliance paperwork your state uses (in Victoria, the Certificate of Electrical Safety) and keep it with your house records.

A safety switch, or RCD, watches the current flowing through a circuit and cuts power in a fraction of a second if some of it leaks to earth, which is what happens when a person gets a shock. It is different from a circuit breaker, which protects the wiring from overload.

• Press the test button on each safety switch regularly. WA’s regulator suggests every three months. It should trip straight away.
• WA requires homes that are sold or leased to have at least two RCDs protecting all powerpoint and lighting circuits.
• Landlords are generally responsible for safety switches in rentals. If you rent and yours doesn’t trip when tested, tell your property manager.
• Adding or replacing an RCD is switchboard work, so it needs a licensed electrician.

If a safety switch keeps tripping, unplug everything on that circuit, reset it, then plug items back in one at a time. A faulty appliance is a common cause. If it trips with nothing plugged in, call an electrician.

• A burning smell, scorch marks or a hot powerpoint or switch
• A tingle or shock from a tap, appliance or metal fitting
• A safety switch or breaker that trips again as soon as you reset it
• Lights that flicker or dim across the house
• Water getting into lights, powerpoints or the switchboard

If there is fire or someone has been seriously shocked, call 000. For fallen powerlines, stay well clear and call your local electricity distributor’s emergency line.
