Plumber through the JRP: file prep, Australian plumbing standards, placement

Plumbers and the JRP: overview

Plumbers (Plumber, ANZSCO 334116Verified 19/06/2026 · Source: Australian Bureau of Statistics (ABS)) are one of the skilled trades that TRA assesses through the Job Ready Program (JRP). The JRP requires you to do real work in Australia in a supervised environment — it cannot be completed from overseas.

ANZSCO version: the plumber code 334116 is the ANZSCO 2022 version (used by the CSOL → visas 482/186); under ANZSCO 2013 (MLTSSL/STSOL → visas 189/190/491) the code is 334111. An ANZSCO code is a classification, not by itself visa eligibility — see Plumber migration to Australia.

What makes plumbing distinctive compared with electrical or welding is the broad scope of work: water, drainage, gas fitting and roofing (plumbing). Your file needs to show clearly which areas you have experience in.

See the migration pathway overview in the companion article on plumber migration to Australia.

Differences between overseas and Australian plumbing

Technical standards: Australia uses AS/NZS 3500 (Plumbing and Drainage) — a standard specific to Australia/New Zealand. Overseas, plumbing work often follows national or project-owner standards. Gap training on AS/NZS 3500 is often very necessary for plumbers trained overseas.

Water pressure and systems: Australian water systems operate to specific parameters for pressure, velocity and flow rate under AS/NZS 3500. The way systems are designed and calculated differs from what you may be used to overseas.

Gas fitting: Gas fitting (gas piping) in Australia is very tightly supervised, and this work often requires a separate licence depending on the type of work and the state — check with the relevant licensing authority before taking it on. If you did gas work overseas, list it clearly in your file.

Hot water systems: Australia has specific rules on hot water temperature, Legionella prevention and solar hot water systems — these are often gap-training content.

Water conservation: Standards on water saving (WELS ratings) and low-flow fixtures are an important part of the Australian construction and renovation market.

Scope of work TRA assesses

TRA assesses against the Certificate III in Plumbing. The core areas:

Plumbing (water supply and drainage):

Installing water supply pipework (copper, CPVC, PEX)
Drainage and sewerage systems
Sanitary fixtures: lavatory, basin, shower, bath
Hot water systems: electric, gas, solar

Drainage (below-ground):

Stormwater systems
Sewerage connections
Maintenance holes and inspection points

Roofing (plumbing):

Guttering, downpipes, roof drainage
Flashing systems

Gas fitting (if you have experience):

Domestic gas piping, appliance connections
Gas meter and regulator

Preparing your Stage 1 file

Plumbing qualifications from overseas:

A vocational or college qualification in water supply and drainage, civil construction with a water specialisation, or plumbing trade training
Related trade certificates (if any)
If documents are not in English, check the current translation requirements with TRA before lodging

Letters confirming experience:

Company name, address, period of employment
Specific description: type of project (residential, commercial, industrial, high-rise), type of work (water supply, drainage, gas, roofing)
Scale of the project: a 1–2 storey home is different from a 10-storey commercial building
Role: lead tradesperson, assistant, or both across different stages

Special note on gas: If you installed gas piping overseas, list it clearly with evidence. Gas fitting is a high-value skill and can help you both in the JRP file and when applying for a gas licence in Australia later.

Common gap training for plumbers trained overseas

AS/NZS 3500: This is the most important set of standards to learn. It covers water services, sanitary plumbing and drainage, and stormwater drainage. You need to understand and be able to look up this standard — you do not need to memorise it, but you must know how to apply it.

Plumbing Code of Australia (PCA): Implemented through state standards. Gap training usually covers how the PCA links to the Building Code of Australia.

Water efficiency and WELS: Water Efficiency Labelling and Standards — how to select and install fixtures with the correct rating.

Australian drainage systems: How to install and test trap seals, inspection openings and sewerage venting — there are points of difference from systems used elsewhere.

White Card: For work on a construction site, a White Card is usually required by the employer and the site — check and complete it early with a training provider.

WHS in a plumbing environment: Manual handling, working in confined spaces, working at heights (roofing work) and excavation safety.

Work Placement

Suitable types of employer:

A plumbing contractor (residential, commercial, industrial)
A construction company with an in-house plumbing crew
A facility management company with a water maintenance crew
A company specialising in hot water systems or solar

How to find an employer:

Seek/Indeed: “plumber wanted” or “plumbing technician”
Master Plumbers Australia — the plumbing industry association, which may help you find an employer
Contact plumbing contractors directly in the region where you live
Community networks in the construction industry in Australia

Work logbook: Record each type of plumbing job in detail: type of project, type of pipe/fitting used, type of fixture installed, hours, supervisor’s signature. Ask TRA and your employer to confirm that your supervisor meets the current JRP requirements.

After the JRP: licensing to practise

The TRA assessment is only one part of the journey — practising as a plumber in Australia usually involves a further licensing step from the state authority, which is a separate process and differs by state.

See the companion article on plumbing licensing after TRA for detail.
