The Certificate III in Engineering – Fixed and Mobile Plant Mechanic (MEM31419) is designed for tradespeople working with heavy machinery, plant equipment, and mechanical systems across industries like mining, construction, agriculture, and transport.

If you’re already diagnosing faults, maintaining equipment, or repairing machinery on-site or in workshops, this qualification helps formalise what you already know.

Through Recognition of Prior Learning (RPL), you can turn years of hands-on experience into a nationally recognised qualification—without stepping away from the job. Instead of starting from scratch, you’re assessed on the real work you’ve already done.

Qualification Overview

This qualification focuses on diagnosing, maintaining, and repairing fixed and mobile plant machinery. It supports workers who already operate in hands-on mechanical roles and want formal recognition to match their capabilities.

What You’ll Learn in MEM30219

Certificate III in Engineering – Mechanical Trade covers the knowledge and skills required by an individual working as an engineering tradesperson within the metal, manufacturing, engineering, or associated industries.

The qualification has been developed with the aim to develop competency through a combination of practical and theoretical strategies, such as those delivered through formal apprenticeship or by formal skills recognition assessment processes.

This qualification is intended to establish a solid foundation of core skills important throughout the metals and engineering industry; the goal is to produce recipients who are qualified to undertake a number of related jobs often closely associated within the workplace.

Basic skills include mechanical cutting, thermal cutting, general machining, tool making, shaping and joining metal, and marking out.

The course also covers more specialised areas of knowledge such as mechatronics, fluid power, computer numerical control machinery, computer-aided drafting, and workplace safety.

Across core and elective units, you’ll master:

Precision measuring, marking-out and hand tooling
Manual and basic CNC machining (turning, milling, drilling)
Fabrication fundamentals: thermal cutting, welding and finishing
Hydraulics, pneumatics and basic fluid-power diagnostics
Workplace safety, quality systems and sustainable practices

By the end, you’ll tackle complex mechanical builds and maintenance tasks with confidence.

Career Outcomes

Graduates of the Certificate III Engineering Mechanical Trade typically move into roles such as:

Mechanical fitter or fitter/turner
CNC machinist or toolmaker
Maintenance technician in mining, manufacturing or defence
Production line setter or shift supervisor

National data shows 89% are satisfied with their RPL training and 87% experience improved work status as a result of it.

In addition, 87.7 percent of certificate holders secure work as technicians and trades workers, with median starting salaries around $104 k. Qualified individuals are most often employed in Other Services (26.5%), Manufacturing (31.6%), and Mining (26.9%).

Licensing and Job Security for Qualified Tradespeople

While most states don’t mandate a licence for general fitting, many mine sites and heavy-industry employers insist on documented trade competence. Holding a mechanical trade certificate:

Satisfies contractor pre-qualification checks
Streamlines High-Risk Work licence add-ons (dogging, rigging, crane)

Demonstrates compliance with ISO 9001 quality frameworks—boosting job security even in downturns
