All 10 Cost GuidesFrequently Asked Questions
Is DIY electrical work legal in Australia?
No. All electrical work must be performed by a licensed electrician in Australia. DIY electrical work is illegal in all states and territories and can result in fines up to $40,000 and imprisonment. The only exceptions are changing light bulbs, resetting circuit breakers, and installing battery-powered smoke alarms.
Can I do my own plumbing in Australia?
Basic tasks like changing tap washers, shower heads, and toilet cistern parts are DIY-friendly. However, most plumbing work — including pipe installation, hot water systems, and drainage — requires a licence. Gas fitting always requires a licensed gasfitter. Unlicensed plumbing can void your home insurance.
How much can I save by DIY painting?
DIY interior painting can save $2,000–$6,000 for a 3-bedroom home. You pay for materials ($400–$700) instead of the full professional cost ($3,500–$6,000). The trade-off is time — expect 3–5 full days of work. Exterior painting on multi-storey homes is better left to professionals for safety reasons.
Can I install my own solar panels in Australia?
No. Solar installation requires both a Clean Energy Council (CEC) accreditation and a state electrical licence. DIY solar installation is illegal, voids all government rebates (worth $2,000–$4,000), and voids manufacturer warranties. Only CEC-accredited installers can access government incentives.
What happens if I DIY licensed work in Australia?
Consequences include: fines and legal penalties (up to $40,000 for electrical), voided home insurance, failed building inspections when selling, safety hazards, and being required to pay for professional remediation. For electrical work, you may also face criminal charges.
Should I DIY or hire a professional for tiling?
Simple floor tiling (straight lay, small areas) is achievable for handy homeowners. However, waterproofing membranes — required under all wet area tiles — must be installed by a licensed waterproofer in most states. Waterproofing failures are the #1 cause of bathroom leaks and can cost $5,000–$20,000 to fix.
