Civil engineering technologists assist civil engineers in the research, design, construction and maintenance of civil engineering projects. Typical projects include dwellings, large buildings, railways, roads, bridges, airports, ports and docks, dams and water supply systems.

Computer engineers are involved in the installation, repair and servicing of computers and associated equipment.

Outdoor council workers are employed by local government bodies to construct and maintain roads, footpaths, gutters, flood controls, fire controls, drainage, sewerage, water mains, parks and gardens, and to dispose of rubbish.

Data and telecommunications cable workers are involved in the installation and maintenance of data and telecommunications cables, which may be located in underground pipes, trenches or overhead systems. They usually work with either copper or fibre optic cables and specialise in a particular procedure or area of expertise.

Doggers attach slings to cranes and direct the movement of loads handled by cranes in locations such as manufacturing plants, construction and mining sites, and the maritime industry.

Electrical engineers design, develop and supervise the manufacture, installation, operation and maintenance of electrical systems. They work on systems for the generation, distribution, utilisation and control of electric power. They also work on electronic systems used for computing, communications and other industrial applications.Electrical engineers may specialise as electrical maintenance engineers, electrical power engineers, electrical design engineers, communications engineers or computer engineers. They may also specialise in areas such as the design and operation of power plants, generators, metal refining, rolling mills, motors and transformers, and in researching new applications of technology or production machinery.

Electrical engineering associates are involved in the planning, design, selection, installation, starting up and maintenance of electrical equipment, facilities, power plant installations, parts and distribution systems. Electrical engineering associates usually work on a range of duties that lie between the trade level and technologist level. Electrical engineering associates may specialise as electrical engineering design drafters, technical officers, substation design officers, test officers and power-system controllers.

Electrical or electronics engineering technologists apply engineering principles to the design, manufacture, installation, commissioning, operation and maintenance of electrical and/or electronic plants and equipment.

Electronic equipment technicians install, service and repair electronic equipment for industrial, commercial and domestic purposes. They work with equipment such as computer networks, mobile phones, radio communications equipment (such as WLAN, two-way radio transceivers, CB radio, and radio and TV broadcast studio equipment), video arcade machines, microphones and public address systems.

Electronics and communications technicians diagnose faults and repair electronic devices, including audiovisual, broadcast, business and medical equipment.

Electronics engineers design, develop, test and maintain electronic parts and systems used in computers, communications, navigation, industry and entertainment.

Electronics engineering associates conduct and assist with the research, design, manufacture, repair and maintenance of advanced electronic equipment and systems. Electronics engineering associates usually have a range of duties that lie between trade and professional engineer levels.

Electronics engineering technicians assist electronics engineers with research, design, manufacturing, operation and maintenance tasks. They may work under the direction of electronics engineers, technologists or associates in all stages of planning, design, maintenance and production.

Engineering managers plan, administer and review engineering and technical operations.

Environmental engineers are concerned with assessing and managing the effects of human and other activity on the natural and built environment. They apply their engineering knowledge and skills to such things as environmental impact assessment, natural resources management and pollution control.
