Research officers plan and conduct research into a variety of issues or areas.

Sampler testers assist engineers, technical officers and other laboratory staff by collecting and preparing samples, carrying out experiments, making measurements with scientific equipment, recording results and presenting results for critical analysis. Sampler/Testers carry out basic sampling and testing, record and present results and clean, maintain and set up equipment for use in experiments. They play an important role in manufacturing quality control.

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.

Statisticians design and apply statistical techniques for creating, collecting and analysing data to draw conclusions, inform decision-making and direct policy within areas such as science, technology, medicine, education, business, finance and government.

Sustainability officers work to create enduring communities that have a positive environmental, economical and social impact.

Taxidermists prepare skins of birds, mammals, reptiles and fish to create life-like 3-D representations for display in museums, or as trophies and memorials. The skin (including fur, feathers or scales) is removed from the specimen, preserved using various methods, and mounted on an artificial frame. Taxidermists in museums also prepare specimens for study, research and collection purposes. They may employ the technique of skeletal assembly to demonstrate the structural and anatomical features of a specimen.

Tissue culture technicians use various techniques to asexually reproduce live tissue, under laboratory conditions, producing specimens that are genetically identical to, or different from, the parent tissue. The process of producing genetically identical specimens is commonly known as cloning. Tissue culture is used for a wide variety of commercially important agricultural and horticultural plants, in the propagation of rare and endangered plant species, and in the growth of tissues or cells used in health and medical research and treatments.

Toxicologists study the harmful effects of chemical, physical and biological agents on living organisms by detecting and examining the symptoms, mechanisms and treatments of poisoning (especially the poisoning of people). They also determine safe or acceptable levels of exposure to particular agents.

Zoologists are biologists who study the structures, characteristics, functions, ecology and environments of animals to increase scientific knowledge and develop practical applications in wildlife management, conservation, agriculture and medicine. Zoologists usually specialise in one aspect of study such as entomology (insects), parasitology (internal and external parasites), ecology (environment of animals), ethology (animal behaviour), ichthyology (fish), mammalogy (mammals), ornithology (birds), herpetology (reptiles) or physiology (functions of animals).
