Electrical lineworker courses in Australia: Cert III, costs and where to study

The qualification

The current qualification is UET30621 Certificate III in ESI - Distribution Overhead, at Release 3 on training.gov.au (August 2025). It replaced UET30619 Certificate III in ESI - Power Systems - Distribution Overhead, which replaced UET30612, so you will still hear the old Power Systems name. It is 24 units: 20 core and 4 electives. The core includes the dogging licence, the boom-type EWP licence (11 metres or more) and chainsaw operation.

Related streams in the same training package include UET30521 Certificate III in ESI - Transmission Overhead for tower and high voltage transmission work, UET30821 Certificate III in ESI - Distribution Underground for cable jointers, and UET30721 Certificate III in ESI - Rail Traction for train and tram overhead lines. Each is its own apprenticeship.

What you will actually learn

• •Working safely near live electrical apparatus, including approach distances, isolation and earthing (UETDREL005)
• •Operating trucks, EWPs and other plant near energised lines without contacting them
• •Electrical theory: DC and AC circuits, single and multiple path circuits, magnetism and transformers
• •Reading network drawings, diagrams, standards and specifications
• •Fabricating and assembling line components such as crossarms and hardware
• •Installing and maintaining poles, structures and hardware (UETDRIS012)
• •Stringing, tensioning, joining and terminating overhead conductors and cables
• •Installing transformers, fuses, switches and other overhead apparatus
• •Connecting low voltage overhead services to customers' premises
• •Inspecting, testing and verifying the overhead network, including maintenance on energised low voltage lines
• •Dogging, rigging and EWP operation to high risk work licence standard, plus chainsaw use
• •Electives such as switching to a schedule, public lighting, vegetation control, mobile generators and drone inspections

Year by year: how the training usually runs

Every employer and training provider structures this differently, and progression is competency based, so you move on when you are signed off, not just when the calendar ticks over. This is a typical pattern for a four-year distribution overhead apprenticeship.

• •First year: induction and long blocks at the training centre covering WHS, electrical theory and pole yard basics, plus EWP and dogging licences once you are old enough. On the job you are a ground hand: digging, rigging, traffic, framing up crossarms on the ground and keeping clear of anything live.
• •Second year: more circuit theory and practical units on poles, hardware and conductors. On the job you start climbing and working from the EWP on isolated, earthed lines under close supervision, helping with pole replacements, conductor work and service lines.
• •Third year: units on transformers, apparatus and energised low voltage work. On the job you take on more of each task, start live LV work under strict procedures once assessed, and go out with the crew on faults and storm restoration.
• •Fourth year: testing, verification and switching units and your final assessments. On the job you lead tasks with a qualified worker checking, build the logged experience your state licence or network authorisation needs, and get ready to work as a qualified lineworker.

How enrolment actually works

You do not enrol first and look for work later. TAFE NSW, for example, says apprentices must be employed in the industry and registered with an Apprenticeship Connect Australia provider. Holmesglen requires you to be employed and registered as an apprentice with an ESI provider. In practice, you win a spot in a network or contractor intake, your employer and an Apprenticeship Connect Australia provider sign you up to a training contract, the contract is registered with your state training authority, and your employer chooses the training provider, which is often its own enterprise RTO.

What it costs, state by state (as at October 2026)

Course fees for this qualification can be large, but in practice the employer pays them in almost every case. These are the current settings for apprentices in each state and territory.

• •NSW: apprenticeships funded under Smart and Skilled are fee-free for training that commences before 30 June 2027. Check the Skills NSW fee-free apprenticeships page and confirm with your provider.
• •VIC: training is delivered with Victorian and Commonwealth funding. Holmesglen lists indicative fees for this course of $26,400 government-subsidised apprenticeship tuition for the whole course ($5,280 concession), plus a $4,602 materials fee and other mandatory fees. That looks scary, but in practice the employer pays: see who pays below.
• •QLD: UET30621 is listed on the Queensland Skills Gateway as funded under Free Apprenticeships for Under 25s, which covers course fees for eligible apprentices who start before 30 June 2027 and continues until they finish. Over 25s should check the Skills Gateway and their provider.
• •WA: apprenticeship fees are subsidised and capped through Jobs and Skills WA, and some qualifications are fee-free. Western Power trains apprentices through its own RTO (listed on training.gov.au as Electricity Networks Corporation). Check the live Jobs and Skills WA fee-free and low-fee list for this qualification.
• •SA: SA Power Networks delivers this course through its own Enterprise RTO under a registered training contract with subsidised training, and eligibility conditions are on the Skills SA site. No public fee is published, so check with your employer.
• •TAS: TasNetworks delivers it through its own RTO (Tasmanian Networks Pty Ltd). The Tasmanian Government's apprentice and trainee training fund helps cover fees. Check the live Skills Tasmania page.
• •ACT: apprenticeship training is subsidised through Skills Canberra's User Choice program, and RTOs must charge a minimum student fee. No ACT-based provider is listed for this qualification, so check the live ACT apprenticeships page and ask your employer.
• •NT: apprenticeship training is subsidised by the NT Government. No NT-based provider is listed for this qualification and no public fee is published for this qualification, so check the live NT Government apprenticeships page and ask your employer.

Who pays

If you are on the Electrical Power Industry Award 2020 (MA000088), clause 15.2(b)(iv) says apprentices who show satisfactory progress must be reimbursed all fees they have paid, and clause 15.2(b)(vii) makes the employer cover excess travel and accommodation costs when block release training needs an overnight stay. Your time at training counts as time worked. Enterprise agreements at the network businesses usually go further, and most networks pay the fees directly. If you work for a contractor on a different award or agreement, check its clauses. Fair Work has the award text and the Pay Calculator.

Where to study

Twenty registered training organisations currently have UET30621 on their scope on training.gov.au. Many are the network businesses themselves. Search the qualification on training.gov.au and open the RTO tab to see the full current list, because scope changes.

• •NSW: TAFE NSW, plus the enterprise RTOs of Endeavour Energy and Essential Energy
• •VIC: Holmesglen (Chadstone) and Chisholm Institute
• •QLD: Ergon Energy Corporation's RTO, which trains Energy Queensland apprentices
• •WA: Western Power's RTO (Electricity Networks Corporation)
• •SA: SA Power Networks Enterprise RTO (RTO 40170)
• •TAS: TasNetworks' RTO (Tasmanian Networks Pty Ltd)
• •ACT and NT: no territory-based provider is listed, so employers use national-scope providers or industry RTOs
• •Industry RTOs with national or multi-state scope include NECA Training, Energy Skills International, Ironbark Training and Performance Training

Doing it without an apprenticeship

You cannot do this course as a school leaver off the street. TAFE NSW offers a non-apprentice route, but only for people who are at least 21, already employed in the industry and have at least two years of relevant experience, usually through recognition of prior learning plus gap training. That suits people already working as line assistants or in related network roles. For everyone else, the qualification is only useful with the network authorisations and on-the-job experience that come with an apprenticeship, and Victoria's lineworker licence specifically requires a four-year contract of training. Put your energy into getting an apprenticeship.
