Forensic scientists apply scientific procedures and techniques to the
examination of potential evidence that may assist in legal investigations.
Forensic scientists use a range of techniques to
examine and analyse materials and objects that are believed to be associated
with a crime.
They often undertake biological analysis in order to detect the presence of
poisons or drugs. Forensic scientists also write reports on their findings,
and may be required to give evidence in court or to provide training to
police staff in collecting evidence from crime scenes. Forensic scientists
may be enlisted to help solve crimes that have occurred anywhere in
Australia.

evidence, which is used in courts of law as part of criminal and civil
investigations.

A wide range of expertise is required for forensic investigations. A
forensic scientist may specialise in chemistry, biochemistry,
entomology, molecular
biology, botany, pharmacology, toxicology,
firearms examination, fingerprint and document examination.

Duties and Tasks
Forensic scientists may perform the following tasks:
- identify illicit drugs
- analyse drugs and poisons in human tissue and body fluids, including
blood alcohol results
- examine and compare materials such as fibres, paints, cosmetics,
oils, fuels, plastics, glass, metals, soils and gunshot residues
- examine human and animal biological material to be compared with
victims and suspects using DNA profiling
- conduct botanical identification of plant materials at trace levels
and whole-plant identification (e.g. cannabis)
- conduct document examinations, both physical (e.g. handwriting,
typewriting) and chemical (e.g. analysis of inks and papers)
- analyse computers and obtain data from electronic devices
- identify firearms and ammunition (forensic ballistics)
- detect, enhance, recover and identify latent fingerprints,
footprints, tool marks, shoe marks, tyre marks and tracks
- examine fire and explosion scenes to establish the origin and cause
- improve the clarity of, and analyse, audio and video recordings
- produce reports, appear in court and present scientific and/or
opinion testimony accurately and in a manner which is readily understood
by the court
- make presentations to a wide variety of audiences on the work of
forensic scientists
- keep contact with, and provide advice to, police investigators,
legal practitioners, scientists and pathologists across a broad range of
disciplines.
Working conditions
Forensic scientists work in the offices and laboratories of government
justice departments and law enforcement bodies. They may be exposed to unpleasant or
disturbing situations, and may be exposed to bodily fluids, firearms,
explosives, or chemical hazards. Forensic scientists travel locally to
attend court cases. They usually work regular hours.

Tools and technologies
Forensic scientists use specialised analytical scientific equipment such as
microscopes, drug detection kits, UV lights and fingerprinting kits. They
also work with computer forensics investigation, analysis and presentation
devices, which detect the molecular make-up of sample materials. They
usually need to wear gloves and may need to wear other protective clothing
such as masks or goggles, depending on the kind of materials they are
working with. They also use laboratory instruments such as test tubes,
pipettes, and portable meters to measure the pH (acid/alkaline level),
conductivity, and dissolved oxygen and ion concentration of samples.
Education and training/entrance requirements
To become a forensic scientist, you usually need to study a degree in
forensic investigation, forensic toxicology and biology or a related area,
followed by a postgraduate course in forensic science.
To become a forensic scientist you usually have to
study forensic science at university (preferably at honours level), followed
by a postgraduate qualification in forensic science. You may also consider
degrees in other relevant areas, which may provide entry into various areas
of forensic science. Relevant areas include biology, botany, chemistry,
physics, dentistry or medicine. To get into the degree courses you usually
need to gain your HSC/ACT Year 12. Prerequisite subjects, or assumed
knowledge, in one or more of English, mathematics, chemistry, physics and
biology are normally required. Most universities in Australia offer degrees
in these areas. Entry to postgraduate courses usually requires completion of
an appropriate bachelor degree.
Employment Opportunities
The main employers of forensic scientists are state and federal government
health departments and state, territory and federal police forces. The
Australian Federal Police, through its Forensic and Data Centres Division in
Canberra, employs forensic scientists in the disciplines of crime scene
examination, fingerprint identification, firearms and ammunition
identification, document examination, forensic biology and forensic
chemistry.
