Physical science technical officers support scientists in the physical sciences. They perform laboratory tests on solids, liquids and gases, analyse test data and carry out a range of technical functions. Work in physical science areas such as physics, chemistry, biotechnology and engineering is usually undertaken in support of other scientists.

Science field officers perform support functions in the field by making observations, collecting and analysing samples, recording information, and looking after the practical tasks involved in maintaining a remote field operation, or operating a city-based office, laboratory or workshop. They may specialise in a number of different areas, such as agriculture, environment, forestry, geoscience and marine science.

Agricultural engineers study and advise on the use of engineering science and technology in agricultural production and management of natural resources. They solve problems relating to such things as sustainable agricultural production, the environmental impacts of intensive agriculture and the post-harvest handling of agricultural products.

Architectural draftspeople complete architects' and other designers' concepts by preparing documents (drawings or plans) and liaising with builders and contractors.

Astronomers study planets, stars, galaxies and other objects in the observable universe and use this information for theoretical and practical purposes.

Biochemists study the chemistry of living systems to increase scientific knowledge and develop ways to apply this knowledge in areas such as medicine, veterinary science, agriculture, environmental science and manufacturing. Biochemistry provides a basis for all the life sciences.

Biomedical engineers apply engineering and scientific methods to find solutions to problems in medicine and the life sciences.

Building surveyors advise on, interpret and enforce laws and regulations regarding building construction and safety.

Cartographic technicians assist cartographers with the analysis of field survey and land management data, aerial photographs and other geographic information sources to prepare maps, plans, charts and diagrams.

Conservators plan, organise and undertake the preservation and conservation of materials and objects in private, public and community collections, including libraries, archives, museums, art galleries, art centres, and historical and archaeological sites. Conservators specialise in a range of areas, including paper, paintings, photographs, social and cultural artefacts, bookbinding and archives, furniture, archaeological materials, buildings and historic sites, outdoor sculpture and large technology objects, textiles and preventative conservation.

Dietary aides assist dietitians to maintain high standards of nutritional care for patients in hospital settings.

Dietitians apply the art and science of human nutrition to help people understand the relationship between food and health, make healthy dietary choices, and prevent and treat illness and disease.

Exercise scientists assist sportspeople to achieve the best possible sporting performance by applying knowledge and techniques from the areas of biomedical science, physiology, biomechanics (the study of human movement), nutrition, psychology and sport assessment.

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.

Geological engineers identify and try to solve problems involving soil, rock and groundwater, and design structures in and below the ground, using the principles of earth science. Geological engineering includes a number of ground engineering specialities such as geotechnical engineering, land remediation, rock mechanics, groundwater hydrology and engineering geology.
