588 Drainers in Australia
A drainer works on drainage systems that move wastewater and stormwater away from a home safely and correctly. They help diagnose blockages, leaks, bad falls, broken pipes and drainage layout problems. For Australian homeowners, a drainer is useful when water is pooling, drains are overflowing, or a new build or renovation needs compliant drainage work. Good drainage protects the home, reduces damage and helps prevent recurring plumbing issues. Every drainer listed here is an ABN-registered business from the Australian Business Register.

Drainer Licensing in Australia
Drainage work is licensed plumbing work in every state (often a plumber-drainer licence). Requirements vary by state, so check the state regulator register before hiring. Confirm the contractor is licensed and authorised for the specific drainage work you need through the relevant regulator, such as NSW Fair Trading, Building and Plumbing Commission VIC, QBCC, Building and Energy WA, Consumer and Business Services SA, CBOS Tasmania, Access Canberra or the NT Building Practitioners Board.
What Affects the Cost
The cost depends on the type of drainage problem, how easy it is to access the pipes, whether excavation is needed, the materials required, and whether the work is a repair, replacement or new installation. Extra complexity can come from tight access, damaged existing pipework, matching older systems, and any compliance work needed. Ask for three written, itemised quotes so you can compare scope, inclusions and exclusions properly.
How to Find a Good Drainer
Look for a licensed drainer with experience in the type of drainage work you need, such as stormwater, sewer or renovation drainage. Ask whether they handle inspections, repairs and compliance work, and whether they can explain the cause of the problem clearly. Check the state regulator register, read recent reviews, and choose someone who provides clear communication and a written scope before work starts.
