Key takeaways
- Most drain cleaning jobs in Australia land between A$150–A$1,300 — known locally as blocked drain plumber.
- Drainage work must be performed by licensed plumbers under state regimes (e.g. VBA in Victoria, NSW Fair Trading, QBCC in Queensland), and sewer connection-point responsibility varies by utility. Root intrusion into earthenware pipes is the dominant blockage cause in older suburbs.
- Prices below are researched national ranges, updated July 2026 — not quotes.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Australia typically run above the national range; smaller towns below it.
How to save
- Get at least three quotes and compare like-for-like scopes, not just totals.
- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.
How to hire a drain cleaning pro in Australia
- Use a licensed plumber — drainage work requires a plumbing licence in every Australian state
- Get a fixed price for the clearance plus the CCTV survey cost
- Ask if they carry both an electric eel and a jetter on the truck — saves a second callout
- For recurring blocks, get a CCTV report; tree roots in clay pipes are Australia's number-one cause
- Check the water utility's responsibility map for shared sewer blockages before paying
- Ask about pipe relining quotes if roots or cracks are found — widely available in AU metros
Red flags
- Unlicensed operators (drainage is licensed plumbing work)
- $0 callout ads with inflated on-site pricing
- Excavation pushed without CCTV evidence
- No compliance certificate for any repair work done

Frequently asked questions
What is the difference between snaking and hydro jetting?
A drain snake (electric eel/auger) bores a hole through the blockage — fast and cheap, but debris and grease remain on pipe walls. Hydro jetting scours the full pipe diameter with high-pressure water, clearing grease, scale and roots properly. Jetting costs more but lasts longer for recurring blocks.
Can chemical drain cleaners fix a blocked drain?
Caustic supermarket products sometimes clear light soap/hair partial blocks, but they don't touch grease plugs or roots, they damage older pipes and seals, and they make the drain hazardous for the plumber who eventually opens it. For a fully blocked drain, go mechanical.
What is pipe relining and when is it cheaper than digging?
Relining inserts a resin-saturated liner into the damaged pipe and cures it in place — a new pipe inside the old one, with no excavation. It usually beats dig-and-replace where the pipe runs under driveways, slabs or landscaping, and most liners carry multi-decade warranties.
When is a CCTV drain survey worth paying for?
After a second blockage in the same line, before buying a house, or when you suspect root intrusion or a collapsed pipe. The camera shows exactly what and where the problem is, so you fix the cause instead of paying for repeat clearances.
Who is responsible for a blocked drain — homeowner, neighbour, or utility?
Generally you own the pipes within your property boundary, while shared or public sewers are the utility's (or body corporate's) problem. If sewage backs up from a shared line, report it to the utility before paying a private contractor — it may be cleared free.
How is drain cleaning priced?
Simple blockages are usually a fixed price per drain (mechanical snake/auger). Stubborn or recurring blockages step up to high-pressure water jetting, and diagnosis of repeat problems adds a CCTV camera survey. Out-of-hours callouts carry a premium.
Why do tree roots block so many Australian drains?
Older suburbs run earthenware (clay) sewer pipes whose joints let roots in, and thirsty natives like figs seek them out. Jetting plus root-cutting clears them temporarily; relining or replacing the affected section is the permanent fix.
