Who runs the pipes
Cairns Regional Council is on the Queensland Government's register as a drinking water provider with water and sewerage services. Outside south-east Queensland that's normal: the state says councils mostly provide sewerage, alongside water.
The exact point where the council's pipe ends and yours begins is something we couldn't confirm. The council's website refused our reader, so rather than guess, we suggest you ask the council when you report a fault. Our guide who owns the sewer pipe shows how other providers split it.
The state's own line for every Queensland water customer: keep the plumbing and drainage on your property in good condition. You can also ask your provider to test a meter you think is wrong, though a fee may apply.
Cairns facts that shape a plumbing job
Two metres of rain
Cairns Aero averages 2019.1 mm a year. January, February and March each average more than 400 mm, and the station records 21.5 days a year with 25 mm or more. Gutters, downpipes and yard drains are working hard for a quarter of the year.
More units than the state average
At the 2021 Census, 15.7% of occupied homes in the Cairns council area were flats or apartments, above Queensland's 12.5%. A further 10.0% were townhouses or semis, and 35.0% of homes were rented.
Humid, never frosty
Mean 9am humidity at the airport is 72% across the year and 78% from February to April. The station has averaged 0.0 days at 2°C or colder since 1942, and its lowest reading is 6.2°C.
A busy water network
In its 2025 figures to the state, the council reported 527 water main breaks, bursts and leaks, 460 of them in the Copperlode/Behana scheme, and 276 sewer main breaks and chokes over 1370.8 km of sewer.
Units, body corporates and shared pipes
If you live in a unit block, check who owns the pipe before you book. Some Queensland apartment buildings have bulk hot water: a central boiler, usually gas, or a bank of heaters, metered for each unit. The body corporate or an energy retailer may own that system, and the state says you're unlikely to be able to change provider.
So for a hot water, drain or leak fault in a unit, start with the body corporate or your building manager. Then book a plumber for anything that's clearly inside your own walls.
Gas in Cairns
Cairns isn't on the Queensland Government's list of places with a natural gas distribution network. Before buying a gas appliance, check whether your home runs on bottled LPG or mains gas, because the burners differ. Any installation or conversion is a job for a licensed gasfitter, and after a flood a gasfitter must inspect your gas installation before it's used again. More on our Cairns gas page.
Checking a Cairns plumber
Plumbers are licensed by the QBCC. Search the business on the QBCC licensee register and the person on the occupational plumber and drainer register; myQBCC runs both. Our guide to checking a licence has the steps.
Licensees must put their licensed name and licence number on their advertising, which the QBCC says includes websites and online directories. When it's missing, ask for it.
For notifiable work, the plumber lodges it with the QBCC within 10 business days of invoicing you, and a copy should reach you within 20 business days of that.

What we would do
Get your drains and downpipes checked in the dry months, before the January to March rain arrives, and know where the water meter and stop tap are. In a unit, find out what the body corporate owns before anything goes wrong, so you know who to ring. When something does fail, ask the council where its pipe ends before paying for digging near the boundary, and look up the plumber in myQBCC before they start.
