FAQs
Why do plumbing prices vary so much between jobs?
The range on this page covers 17 different kinds of plumbing work, from small repairs to large installations, so the spread is wide. Within one job the price moves with size, access, materials and urgency. A tradie who has seen the job can quote it; a page cannot.
Do these prices include GST?
Yes. Every figure here is GST-inclusive and assumes a standard residential job with reasonable access. A written quote from a licensed business must also show whether GST is included.
Why is plumbing dearer in some states?
Labour rates, licence requirements, insurance thresholds and the cost of getting materials to site all differ by state, and metro rates run above regional ones. The state table applies a cost index for each capital city to the national range; regional prices can sit outside it.
