How to Become a Plumber in Australia

Training, licensing, earnings, and career pathways

Plumbers hold a critical shortage listing in Australia in 2026, and the trade has never been more secure: every new home, renovation, bathroom and commercial build needs plumbing, and the national housing target of 1.2 million homes means a decade of guaranteed demand. Plumbing is also one of the highest-earning trades — newly qualified plumbers earn $60,000–$80,000, experienced ones $80,000–$110,000+, and sole traders in demand areas clear $140,000–$150,000. It is a trade with real variety: every day is a different job, a different site and a different problem.

Overview

Plumbing splits into several streams that share one apprenticeship: residential and commercial plumbing (water supply, drainage, gas fitting), roofing (stormwater and roof plumbing), mechanical services (air-conditioning and heating systems) and hydraulic services on commercial projects. The common thread is the licensed responsibility for water and gas safety — the reason the trade is regulated in every state. The mechanism that drives demand: water infrastructure is ageing, housing is booming, and every bathroom renovation needs a licensed plumber by law — you cannot DIY plumbing work in Australia the way you can painting or tiling.

The Apprenticeship Pathway

Plumbing apprenticeships run 4 years: paid on-the-job training with a licensed plumbing contractor plus TAFE study (typically one day a week or block release) toward the Certificate III in Plumbing (CPC32420). Entry: Year 10 or 12, with maths important — plumbing involves calculating pipe sizes, fall and water pressure. First-year apprentice award rates run roughly $615–$724 per week in 2026–27 (about $17–$26 per hour depending on age and stage), rising to around $985–$1,116+ by year four; the MIGAS schedule for plumbing apprentices starts at $629.23 per week in year one and reaches $1,099.48 in year four. Adult apprentices (21+) start at a higher stage rate. The off-the-job component is substantial — plumbing is one of the most theory-heavy trades — so expect genuine study time alongside the site work.

Licensing

Plumbing is licensed in every state, and the licence types vary: NSW Fair Trading issues plumbing and gasfitting licences (open and restricted); Victoria's VBA licenses plumbers and gasfitters (with the famous "VBA registration" and the new points-based licence system); Queensland's QBCC and the Plumbing Industry Council handle plumbing licensing; WA's Plumbers Licensing Board covers the state. Most states now use a points or registration system that records your CPD (continuing professional development) — plumbers must log training hours to renew. The mechanism: after your apprenticeship and trade qualification, you typically need 12 months of supervised work experience before holding an open licence, so factor that into your timeline. Specialised endorsements (gasfitting, roof plumbing, backflow prevention) add further scope and earning power.

Wages & Earnings

The award floor for qualified plumbers sits around $29–$31 per hour in 2026–27 (Plumbing and Pipe Trades Employees Award, plus the Building and Construction On-Site Award for construction work), with casual loading and penalty rates on top. The market pays well above: newly qualified plumbers earn $60,000–$80,000, experienced $80,000–$110,000+, and those who specialise in gasfitting, backflow or commercial hydraulics earn a premium. Self-employed plumbers charge $90–$150 per hour and, in high-demand areas like Western Sydney, routinely turn over $140,000–$150,000+ — the shortage means work is never the constraint, capacity is. The mechanism: plumbing earnings are unusually consistent because the work is essential and non-deferrable — a leaking pipe gets fixed this week, not next month.

Specialisations & Career Paths

The specialisation ladder: gasfitting (adds gas work and higher rates), roof plumbing, backflow prevention and fire services (commercial, high-value work), hydraulic design (commercial drafting — a desk job that pays off the trade), and mechanical services (air-conditioning and refrigeration). Many plumbers move into project management, building supervision or their own business with a team. The industry also faces the same demographic wave as every trade — experienced plumbers retiring faster than apprentices qualify — which is why the shortage list is critical, not just high.
