Toxicologists test samples, read studies and interpret exposure data to judge whether a substance is harmful and at what dose. Most work in laboratories attached to hospitals, research institutes, government agencies or pharmaceutical companies, alongside chemists, clinicians and regulators. The role sits close to pharmacology, but where pharmacologists study how drugs act in the body, toxicologists concentrate on harm, from medicines and industrial chemicals through to pesticides and contaminated water.
How much do toxicologists earn?
The median full-time salary for a toxicologist is $103,000 per annum, before tax, up $21,900 since 2018.
Sector moves pay more than anything else: pharmaceutical, consulting and senior regulatory roles generally sit above hospital, university and government laboratory positions. A PhD or a specialist reputation opens the higher bands, and experienced toxicologists who shift into regulatory affairs or private consulting tend to earn at the top of the range. Part-time and fixed-term contracts are common in research, which changes total annual earnings even when the hourly rate is similar.
What does a toxicologist do day to day?
The list below is what fills most weeks; the exact mix shifts with seniority and whatever stage the current work is at.

Is the job growing?
About 1,800 people work as toxicologists in Australia, and employment is projected to grow 6% over the decade to 2035. That's modest growth: demand is steady rather than booming.
How do you become a toxicologist?
Here's the path most toxicologists take, step by step.
- 1Complete a science degree
A bachelor degree in toxicology, pharmacology, chemistry or biochemistry is the standard entry point, usually three years full time. Some universities offer toxicology as a major, otherwise you build the subject through a pharmacology or chemistry degree with toxicology electives. About 52% of people working as toxicologists hold a bachelor degree as their highest qualification.
- 2Add postgraduate study
A fourth-year honours project or a master's in toxicology builds the research and analytical skills employers ask for, and around 26% of toxicologists hold a postgraduate qualification. A PhD is usual for research institutes and some regulatory science roles, though not for hospital or poisons information work.
- 3Get laboratory experience
Vacation work, a research assistant role or a hospital laboratory position gives you time on instruments such as LC-MS/MS and GC-MS, and on the quality systems around them. Graduate employers ask for this more often than for a higher degree.
- 4Choose a specialty and join the profession
There is no licensing requirement to work as a toxicologist in Australia, but bodies such as the Australasian College of Toxicology and Risk Assessment and the Royal Australian Chemical Institute run meetings and training that help you specialise in clinical, forensic, environmental or regulatory toxicology.
Ready to apply as a toxicologist?
Whether you're working toward becoming a toxicologist or already are one and want a hand with the next step (sharpening your resume for ATS screening, tightening your cover letter, or knowing what you'll actually be asked at interview), here are examples grounded in this specific role, not generic templates.
What jobs can a toxicologist move to?
Moving into Occupational Hygienist typically comes with the biggest pay rise, worth $8,800 a year more on average.
| Move to | Typical pay change | Overlap | Retraining |
|---|---|---|---|
| Occupational Hygienist Toxicologists understand chemical hazards and exposure limits, skills that carry into assessing and controlling workplace health risks. | +$8,800 | 55% | short course |
| Pharmacologist Toxicologists bring a strong grounding in how substances affect the body, which transfers directly to studying drug actions and safety. | +$6,200 | 62% | minimal |
| Medical Laboratory Scientist Toxicologists bring laboratory and analytical experience, though clinical diagnostic training is needed to work in medical testing. | +$3,900 | 62% | requalify |
| Biotechnologist Toxicologists bring laboratory and safety assessment skills that support biotech work on new therapies and their potential harms. | −$1,600 | 57% | short course |
| Forensic Scientist Toxicologists bring analytical skills and knowledge of poisons and drugs, useful for forensic testing and interpreting evidence. | −$7,300 | 54% | short course |
Moves are chosen from Jobs and Skills Australia's Data on Occupation Mobility, which follows income tax records between 2011-12 and 2020-21, together with entry requirements and skill overlap.

What's it like being a toxicologist?
Toxicology mixes laboratory work with desk analysis, and the balance depends on the employer: hospital and poisons roles lean clinical and advisory, while research and industry roles are heavier on testing and reporting. The rhythm is steady rather than fast, though regulatory deadlines bunch the work into intense stretches. It suits people who are comfortable stating what the evidence supports and what it does not.
What people like
- Your findings change real decisions. A safety assessment can shift a medicine's label, a workplace exposure limit or a pollution clean-up plan, so the reasoning you write has a visible consequence.
- The science is varied. One week might be a batch of blood samples, the next a literature review on a pesticide and a call with a poisons centre about a specific case.
- Room to specialise. Clinical, forensic, environmental and regulatory toxicology are distinct paths, and you can move between them without starting your career over.
- Careful work is valued. Accuracy and documentation matter more than speed in this field, which suits people who like getting the details right.
What people find hard
- The evidence is often incomplete. You frequently work with limited exposure data and have to state a conclusion with caveats, when the people asking want a plain yes or no.
- Regulatory deadlines. Safety dossiers and submissions have fixed dates, so the weeks before them can be long and the reading is heavy.
- Answers take time. A toxicity study or a long-term exposure assessment can run for months or years before it produces a result.
- Routine testing. Part of every week goes to running batches, calibration and quality control, which is repetitive but not optional.

Will AI replace toxicologists?
Toxicology sits in the middle: the analytical and literature-heavy parts of the job are increasingly automated, while interpretation, case advice and regulatory conclusions still depend on a person. Instruments such as LC-MS/MS and GC-MS have long handled detection and quantification, and machine learning models now offer a first-pass prediction of toxicity from a chemical's structure. What that changes is where the working week goes, not whether the role exists.

Common questions about becoming a toxicologist
Straight answers to the questions people ask most.
How much do toxicologists earn in Australia?
Toxicologists earn a median of $103,000 per year before tax. Sector moves it most, with pharmaceutical, consulting and senior regulatory roles generally above hospital, university and government laboratory positions. It is a median for full-time workers, so half earn less than this.
How do you become a toxicologist?
Most toxicologists start with a science degree in toxicology, pharmacology, chemistry or biochemistry, then add honours, a master's or a PhD. Laboratory experience matters as much as the qualification, so vacation work or a research assistant role is worth chasing early. There is no national licence to practise.
Are toxicologists in demand in Australia?
Toxicologists are currently not in shortage, and employment is projected to grow 6% over the decade to 2035. With only about 1,800 people in the occupation, openings tend to be specialised and often go to people moving across from pharmacology, chemistry or biochemistry. Hospital, government and research institute job lists are worth watching alongside industry sites.
Will AI replace toxicologists?
AI is changing parts of the job rather than the whole of it. Machine learning models can predict likely toxicity from a chemical's structure and screen published studies quickly, which speeds up the background work behind an assessment. Someone still has to decide whether a prediction applies to a real exposure, advise on a poisoning case and take responsibility for a regulatory conclusion.
What can toxicologists move into?
Pharmacology is a close move, because the understanding of how substances act in the body carries straight across, and pay is $6,200 more. Occupational hygiene uses the same knowledge of chemical hazards and exposure limits to assess workplace risk, with pay $8,800 more. Forensic science draws on the analytical skills and poison knowledge too, though pay is $7,300 less.
Do you need a PhD to work as a toxicologist?
No, though about 26% of toxicologists hold a postgraduate qualification and a PhD is usual for research institutes and some regulatory roles. Hospital laboratories, poisons information services and industry testing teams hire on laboratory skill and experience as much as on the degree level. A PhD mainly opens the research and senior scientific pathway.
