What most people call the Sunshine Coast is two council areas. Sunshine Coast Council covers the coast from Caloundra and Kawana through Mooloolaba, Maroochydore and Coolum, inland to Buderim, Nambour and the hinterland around Maleny; Noosa Shire, separate again since 1 January 2014, takes in Noosa Heads, Noosaville, Tewantin and Cooroy. Each council handles its own plumbing approvals and keeps its own backflow register, while Unitywater runs the water and sewer networks for both, and for Moreton Bay. The QBCC licence and advertising rules are the same as anywhere in Queensland, and our Brisbane plumbing page sets them out.
The biggest change for plumbers here is the meter. Unitywater has been rolling out digital meters since early 2026, starting where the infrastructure is older and leaks are more common, and the rollout will widen over the next few years. Owners get a letter up to six months before their meter is changed, and another notice shortly before the visit. Once it’s in, leak notifications go to the primary owner, partly, Unitywater says, so that several owners don’t hire several plumbers for one leak. An owner who leaves a notified leak unfixed can’t claim Unitywater’s concealed leak allowance, so the alert gives them a real reason to call someone.
Older housing brings its own drainage. Sunshine Coast Council explains that a combined sanitary drain is shared by two or more properties and runs to one Unitywater sewer connection point. Maintenance falls to the owners of the connected properties, the owner whose land holds a defective section has to fix it, and whoever applies for a separate connection pays for it. Council’s Plumbing Services can help an owner find out about their sanitary drainage, and copies of drainage plans may be available from council records.
Properties off the sewer follow two sets of rules. On the Sunshine Coast side, a licensed site and soil evaluator assesses the block, a licensed drainage contractor installs the system, servicing runs from quarterly to yearly and service reports go to council. Noosa Council says treatment plants are serviced every 3, 6 or 12 months depending on the system, with a report lodged within 10 days of each visit, and recommends pumping out septic tanks every five years. A plumber servicing both areas can set that out once on the site and save owners a phone call.
Sunshine Coast Council counted about 149,000 dwellings in its area in 2021, projects it will need roughly 90,000 more, and expects about 8,000 new residents a year. New homes need connections and hot water systems, and people who have just moved have no plumber yet.
