Medical laboratory technicians carry out routine laboratory tests and other procedures used in the diagnosis and treatment of diseases and disorders of the human body.

Medical practitioners diagnose physical and mental illnesses, disorders and injuries, and prescribe medications and treatment to promote or restore good health.

Medical scientists conduct medical laboratory tests to provide information for diagnosing, treating and preventing disease. A medical scientist may specialise in haematology, immunology, transfusion science, clinical biochemistry, microbiology, histopathology, cytology, molecular genetics or virology.

Mental health nurses play a vital role in providing compassionate care, support and treatment to individuals with mental health conditions. They assess patients, develop personalised care plans, administer medications and collaborate with a multidisciplinary team to promote mental wellbeing and improve quality of life.

Metal press operators use automatic or semi-automatic machines or machine tools to shape and form metal products or parts.

Metal surface finishers work in metal fabrication and engineering production operations. They finish metal products by cleaning, polishing, filing or bathing them in acid solutions. They also apply protective and decorative coatings.

Metal trades assistants assist metal engineering tradespeople by performing routine tasks.

Metallurgical technicians test materials as part of mineral processing and metal refining, or for research purposes, and provide technical support to metallurgical engineers.

Metallurgists research, control and develop processes that are used in extracting minerals from ore (rock) for refining metals.

Meteorologists forecast the weather and study the atmosphere to improve the understanding of climate.

Microbiologists study microscopic forms of life such as bacteria, viruses, protozoa, algae and fungi to increase scientific knowledge and develop medical, veterinary, industrial, environmental and other practical applications.

Midwives provide care, education, advice and support to women and their families during pregnancy, labour and birth, and provide postnatal care to women and babies in the early weeks following birth.

Milliners design and make hats and other headgear such as caps, berets, bonnets, fascinators and bridal headpieces, using materials such as felt, fabric, fur, leather, straw and artificial flowers.

Miners operate equipment to excavate, load and transport coal, ore, mineral sand and rock, either underground or in open-cut mines.

Mineral processing operators use equipment to process mineral ores until the final form or a concentrate is produced. Commonly processed minerals include gold, silver, nickel and iron ore. Mineral-bearing ore is subjected to various processes to extract the minerals. The ore is first crushed, then processing equipment (such as screens, grinding mills, filters, flotation cells, tanks and conveyors) is used to extract concentrated minerals. At the end of the treatment process the minerals may be produced into their final form by smelting, or as a bulk concentrate in preparation for shipment from site.
