Plumbers do far more than fix leaky taps. They install and maintain the water, gas, drainage, roofing and heating systems that make buildings safe and liveable. It's a licensed trade with strong pay, constant demand and real variety. If you want a career where no two days are the same and your skills are always needed, a plumbing apprenticeship is one of the best trades you can pick.
This guide covers what a plumbing apprenticeship involves in Australia — the work, the training, what you'll earn, how long it takes and how to get started.
What the work involves
Plumbing is a broad, licensed trade. Depending on your employer and specialty you might work in general plumbing, gasfitting, drainage, roofing, mechanical services or fire protection.
Typical tasks include:
- Installing and repairing water supply and drainage systems
- Fitting bathrooms, kitchens, hot water systems and appliances
- Gasfitting — installing and connecting gas appliances and lines
- Roof plumbing — guttering, downpipes and flashings
- Reading and interpreting plans and specifications
- Fault-finding, maintenance and emergency repairs
- Working to strict plumbing standards and codes
You'll work in homes, on construction sites and in commercial and industrial settings. It's physical, hands-on work — sometimes in tight or messy spots — but it's also skilled and safety-critical, especially gas and drainage work.
Qualification and training
Most plumbing apprentices complete the Certificate III in Plumbing (CPC32420 or its current equivalent), often followed by further study to gain the endorsements needed for licensing.
Training happens two ways:
- On the job: most of your learning is hands-on with a licensed plumber.
- Off the job: you attend TAFE or an RTO for theory and practical assessment, usually one day a week or in blocks.
Plumbing is a licensed trade, so after your apprenticeship you'll need to gain the relevant licence or registration through your state or territory regulator before you can work unsupervised or as a contractor. You'll also need a White Card for construction sites and usually a driver's licence. To understand how the theory and practical parts fit, read TAFE vs On-the-Job Training.
How long it takes
A plumbing apprenticeship usually runs around four years full-time. It's formalised through a training contract registered with your state or territory training authority. Getting fully licensed can take additional study and experience beyond the apprenticeship, depending on the endorsements you want (like gasfitting or drainage).
There's a probation period at the start — see Apprenticeship Contracts and Probation Explained.
What you'll get paid
Plumbing apprentice wages are set by the Plumbing and Fire Sprinklers Award. Your pay is a percentage of the qualified rate and steps up each year as you progress.
You may also be entitled to:
- A tool allowance
- Travel and fares allowances — see Travel and Fares Allowances on Site
- Overtime and penalty rates
- Superannuation paid on top of your wage
Because wage rates change, use the Wage Calculator for a current estimate and read the Apprentice Pay Guide. The Fair Work Ombudsman is the official source for entitlements. Licensed plumbers are consistently well paid, and those who take emergency call-outs or contract work can earn strongly.
How to get started
Employers value reliability, attitude and problem-solving over top marks, though decent maths helps. The practical path:
- Step 1: Finish school (Year 10 minimum; Year 12 preferred). Maths is genuinely useful here.
- Step 2: Get your White Card and, if you can, a driver's licence.
- Step 3: Consider a pre-apprenticeship in plumbing to build basics and show you're serious — see Pre-Apprenticeship Courses: Are They Worth It?.
- Step 4: Apply for vacancies. Browse apprenticeship jobs and create a free profile to reach employers.
- Step 5: Prepare thoroughly for interviews with our interview tips and How to Practise for an Apprenticeship Interview.
Group training organisations are a common way into plumbing — see How Group Training Organisations Work.
Skills and traits that help
Good plumbing apprentices tend to be:
- Practical, methodical problem-solvers
- Comfortable with physical work in awkward spaces
- Safety-conscious, especially around gas and drainage
- Reliable and punctual — see Reliability Beats Talent
- Good communicators, since a lot of work is in people's homes

- Moving into commercial, industrial or hydraulic services work
- Becoming a leading hand or supervisor — see Becoming a Leading Hand
- Getting your contractor licence — see Getting Your Contractor Licence
