How do I become one?
Education and training
To become a diesel motor mechanic, you usually have to undertake an apprenticeship in automotive technician (heavy vehicle road transport). The apprenticeship usually takes between 42 and 48 months to complete, and is available as a school-based apprenticeship.
Apprenticeships and traineeships
As an apprentice or trainee, you enter into a formal training contract with an employer, enabling you to complete training towards a nationally recognised qualification. You spend time working and learning practical skills on the job and you spend some time undertaking structured training with a registered training provider.
You can do an apprenticeship or traineeship if you are a school-leaver, re-entering the workforce or as an adult or mature-aged person wishing to change careers. You can even begin your apprenticeship or traineeship while you're still at school.
If you are still at school you can access an apprenticeship through your school. Talk to your school's VET Co-ordinator to start your training now through VET in Schools. If you are no longer at school you can apply for an apprenticeship or traineeship and get paid while you learn and work.
