Why Complete A Heavy Vehicle Mechanic Apprenticeship?
Some key reasons to pursue a career with a Heavy machinery mechanic apprenticeship include:
- In-Demand Skills: The transport industry plays a crucial role in the Australian economy, so this field is always in demand for skilled technicians.
- Job Security: As transport is essential, heavy commercial vehicle technicians can have a permanent job, even during economic fluctuations.
- Competitive Salaries: Skilled technicians earn competitive salaries, making it a financially good alternative for those seeking this as a career choice.
- Hands-On Work: If you prefer hands-on work to desk jobs and enjoy fixing tangible issues, this career is for you as it offers a dynamic environment where apprentices are always on the move.
- Continuous Learning: Technology in heavy vehicles constantly evolves, offering ongoing learning and professional growth opportunities.
Heavy Commercial Vehicle vs Light Vehicle: What Is the Difference?
The main difference between Heavy Commercial Vehicle Technology and Light Vehicle Technology lies in the types of vehicles and skills involved.
Heavy Vehicle Technology focuses on larger, heavy-duty vehicles like trucks and buses, including heavy-duty mechanical, hydraulic, steering, braking and diesel systems.
Light Vehicle Technology focuses on cars and other light vehicles, with training centred on servicing, diagnostics and repair of light vehicle systems and components.
The pathway that suits you will depend on the type of vehicles and mechanical work you are most interested in.

Where Heavy Diesel Apprentices Work
Heavy commercial vehicle apprentices work across transport and logistics fleets, bus and coach operators, truck dealerships, mining and civil contractors, and council depots. Because heavy vehicles are kept in service for far longer than cars, the trade tends to be steady work, and qualified heavy diesel mechanics are consistently in demand across regional and metropolitan Australia. If you would rather work on cars and light commercials, the Certificate III in Light Vehicle Mechanical Technology is the equivalent pathway, and earthmoving and plant work sits under the Certificate III in Mobile Plant Technology.

FAQ
Can a heavy vehicle mechanic work on cars?
A heavy vehicle mechanic can work on cars in practice, but the qualification is not the same. AUR31120 trains you on trucks, buses and heavy diesel systems, including air braking and hydraulics, rather than on light vehicle engine management. Many workshops will accept a heavy vehicle qualified mechanic for general light vehicle work, though some employers and licensing arrangements require the light vehicle certificate specifically.
How long is a heavy diesel mechanic apprenticeship?
A heavy diesel mechanic apprenticeship generally takes three to four years. You are employed and paid for the whole period, working with your host employer and completing off-the-job training towards AUR31120. Progress is measured against competencies, so the exact length depends on how quickly you work through them.
What is the difference between a heavy diesel mechanic and a diesel fitter?
The difference between a heavy diesel mechanic and a diesel fitter is mostly where the work happens and what it covers. A heavy diesel mechanic services and repairs trucks, buses and heavy road vehicles. A diesel fitter more often works on fixed or mobile plant in mining, agriculture and civil construction. The underlying engine and hydraulic skills overlap heavily, and people move between the two.
Do you need a truck licence to be a heavy vehicle mechanic?
You do not need a truck licence to start as a heavy vehicle mechanic apprentice. A standard driver licence is useful from the beginning, and many apprentices gain a heavy vehicle licence during or after their apprenticeship because it makes road testing and moving vehicles around the yard far easier. Some employers will support you to obtain one.
