Geographic information systems officers design, develop and customise geographic information systems and provide technical and analytical support to address issues such as environmental management, exploration and mining, land ownership and titles, urban and regional planning, utilities and asset management, and demographic marketing.

Geologists study the nature, composition and structure of the earth to locate materials and minerals, and to increase scientific knowledge. They also advise on the extraction of minerals, as well as on environmental protection, the rehabilitation of land after mining and on civil engineering projects.

Geophysicists study the structure and composition of zones below the surface of the earth by taking measurements using seismic, gravity, magnetic and electrical data collection methods. The two main divisions of geophysics are exploration geophysics, which deals with the search for Earth's resources, and global geophysics, which uses the same techniques to study Earth as a whole and study earthquakes, magnetic fields and other phenomena. Geophysicists often specialise in areas such as seismology and seismic interpretation, borehole geophysics, mineral exploration, engineering geophysics, environmental or groundwater geophysics, or computer processing and software development.

Interior designers design and supervise the construction or redevelopment of building interiors.

Laboratory workers assist scientists, engineers, technical officers and other laboratory staff by collecting and preparing samples, carrying out experiments, making measurements with scientific equipment, recording results and presenting them for critical analysis.

Landcare workers perform a range of tasks to maintain and restore native bushland and farmland.

Law clerks perform a variety of legal tasks under the supervision of solicitors, barristers or clerks of court. Law clerks may assist their employers in all areas of law, including probating (proving the validity of wills), conveyancing (dealings in land and property), criminal law, family law, wills and power of attorney, insurance law, environmental law, human rights law, company law and civil litigation.

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.

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

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.

Natural resource managers develop conservation plans for nature reserves, land and other natural resources, so that people can use these resources in an ecologically sustainable way. Natural resource managers specialising in land and biological resources work in agencies where they can apply ecological and planning principles to the management of renewable resources such as forests, grasslands and agricultural landscapes. Natural resource managers specialising in water and soil resources may apply their skills to several areas, including irrigated agriculture, drainage, water supply, water catchment management, pollution control and rehabilitation after mining activities.

Naval architects design and oversee the construction, survey and repair of marine craft and floating structures, including naval craft, passenger and cargo ships, submarines, high-speed ferries and catamarans, tugs, boats, yachts and oil rigs.

Occupational health and safety officers coordinate health and safety systems in an organisation. They identify hazards, assess risks to health and safety, put appropriate safety controls in place and provide advice about accident prevention and occupational health to management and employees. With experience and sometimes further training, occupational health and safety officers may become auditors, who inspect a workplace's level of compliance with health and safety standards.

Park rangers control, supervise and manage national parks, scenic areas, historic sites, nature reserves and other recreational areas.

Physicists study the behaviour of the physical world at the most basic level and find practical ways to apply new knowledge gained from their research in areas of science and technology.Physicists are usually identified within three broad roles:• theoretical physicists, who develop theories or models of how particular aspects of the world work• experimental physicists, who test these theories, determining their limits and suggesting new approaches to them• applied physicists, who apply these findings in practical settings, such as within industry and through the introduction of new technology.There is interaction between all three roles and physicists generally have skills in each of these areas.
