Massage therapists assess and treat the soft tissue of the body for therapeutic purposes.

Master fishers control fishing operations to catch and preserve fish, crustaceans and molluscs in ocean, coastal and inland waters, using equipment such as nets, lines, traps, pots and towed dredges.

Materials engineers investigate the properties of metals, ceramics, polymers, plastics and other materials, and develop and assess their commercial and engineering applications. Materials engineers may specialise in metals, ceramics, polymers, plastics or composites.

Mathematicians apply and develop mathematical principles to solve problems in all areas of the sciences, technology, social sciences, business, industry and commerce.

Meat processing workers perform a wide range of tasks, including handling, slaughtering and processing livestock, operating processing and rendering equipment, dispatching products, and keeping records.

Mechanical engineers plan, design and oversee the development, installation, operation and maintenance of machinery. They conduct research to solve practical engineering problems and improve efficiency.

Mechanical engineering associates assist mechanical engineers and engineering technologists with the design, manufacture, construction, operation and maintenance of machines, manufacturing equipment, mechanical installations and mechanical facilities. They usually have a range of duties carried out under the direction of mechanical engineers and engineering technologists.

Mechanical engineering technicians carry out technical support functions as part of mechanical engineering research, design, manufacture, operations and maintenance. They may work under the direction of mechanical engineers, technologists and associates in all stages of planning, design, maintenance and production.

Mechanical engineering technologists design, inspect, manage and test technologies, systems and procedures in mining, manufacturing or processing industry plants.

Mechatronic engineers design and maintain machinery with electronic and computer control systems, such as aircraft, robots, motor vehicles, cameras, power generators and mining and chemical plant machinery.

Media presenters deliver a variety of radio, television and live programmes, including all music formats, music and chat programmes, interview and talkback programmes, news bulletins and sports programmes. They may also present rock and classical music concerts that are broadcast live to air, and pre-recorded programmes such as documentary and music specials.

Medical imaging technologists operate X-ray and other imaging equipment, such as magnetic resonance imaging (MRI) and ultrasound, to produce radiographic images that are used in the diagnosis and subsequent management of disease or injury. Experienced medical imaging technologists may be able to develop further skills in image interpretation.
