What matters for plumbing in Melbourne

Melbourne averages only 575 mm of rain a year at Olympic Park, well under half what Sydney gets, but it falls fairly evenly across every month. That combination of a modest total and long dry spells is what drives the summer shrinkage and winter swelling in the city's clay soils.

In Victoria a licensed plumber must give you a signed compliance certificate for any plumbing work valued at $750 or more, counting labour, materials and fittings. The Building Act sets the trigger at $500 and the Plumbing Regulations lift it to $750, so the threshold is lower than most people expect.

Nearly all gasfitting work in Victoria needs a compliance certificate no matter how little it costs, so a gas cooktop or heater swap is certified even when it falls under the $750 rule. Ask for the certificate before you pay.

Victoria splits plumbers into registered and licensed, and only a licensed plumber can sign a compliance certificate. Higher risk work such as below ground sanitary drains, cooling towers and any job worth $750 or more must be done by a licensed plumber or by someone working under one.
