Course in Transfer Cases and Reduction Gears in Off-Road Vehicles — studying from Australia
Off-road and special-purpose vehicles are central to Australia's mining, agriculture, construction and emergency services sectors. Remote geography and harsh conditions create strong demand for robust machinery, including haul trucks, agricultural equipment and specialist fire and rescue vehicles. Engineers work on hydraulics, drivetrains, operator safety and machine automation. Employers include mining equipment manufacturers and dealers, agricultural machinery firms, construction companies and government fleet agencies.
Fees for Australia: A$868 (AUD), with instalments and employer sponsorship available.

Questions from Australia
Will this qualification be recognised by Australian engineering bodies for off-road vehicle work?
SEIUM qualifications are private and not accredited by Engineers Australia or any national body. Recognition is decided by employers or the relevant professional body assessing your application. Engineers Australia assesses competence independently, so check its requirements before enrolling if membership is your goal.
Which Australian employers work with off-road and special vehicles and machinery?
Mining and agricultural equipment makers, fleet operators, defence and emergency service vehicle suppliers, and four-wheel-drive modification businesses are examples. Their hiring decisions depend on their own criteria. Relevant experience and a practical final project are often as important as the qualification.
Can I study this online while working in Australia, and is there support?
Yes, the programmes are 100% online and taught in English, and each student has an assigned technical tutor. You can study from anywhere in Australia without a student visa. Fees are payable in instalments, and employer sponsorship is possible; check the total hours and plan a realistic schedule.

How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: students progress at their own pace within the intake, which makes it possible to combine the course with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is KISSsoft, Romax, SolidWorks, advanced Excel, in free, academic or evaluation versions. Tests are studied using real procedures for dismantling and inspecting transfer cases, traction tests on terrain, analysis of clearances and gear wear. Assessment is continuous, module by module, plus the final integrating project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
