Private investigators work for law firms, insurers, businesses and private clients, and much of the job happens outside an office: on the road, at an address, or in public records. Unlike police, they have no powers of arrest, search or phone interception, so their evidence comes from surveillance, interviews and open sources and has to stand up in a written report. Most states and territories require an investigator licence, which usually follows a Certificate III in investigative services and a police check.
How much do private investigators earn?
The median full-time salary for a private investigator is $78,000 per annum, before tax, up $16,500 since 2018.
Pay depends heavily on the sector: insurance and corporate investigation generally pays better than general process serving, and the class of licence you hold decides what work you are allowed to take on. Night, weekend and on-call surveillance usually attracts penalty rates or a loading, which can lift a week's earnings above the ordinary rate. Because a large share of investigators are sole traders or work for small agencies, income also follows how much billable work they can keep on the books.
What does a private investigator do day to day?

Is the job growing?
About 500 people work as private investigators in Australia, and employment is projected to grow 4% over the decade to 2035. That's modest growth: demand is steady rather than booming.
How do you become a private investigator?
Here's the path most private investigators take, step by step.
- 1Get the entry qualification
A Certificate III in Investigative Services is the standard starting point and covers surveillance, evidence handling and the legal limits of the work. TAFE and private training providers deliver it, usually over roughly six months full time or part time while you keep working. About 34% of people in the job hold a certificate III or IV as their highest qualification.
- 2Apply for your state or territory licence
Licensing sits with the police or the fair trading agency in each jurisdiction, and the requirements differ, so check the rules for where you plan to work before you enrol in anything. Most ask for a relevant qualification, a national police check and sometimes a period of supervised experience before the licence is granted.
- 3Build supervised casework
New investigators learn the practical side on the job, usually inside an agency, an insurer or a law firm where a licensed supervisor signs off on reports. You build hours across surveillance, interviewing and records work, and many people arrive from insurance claims, security, legal support or policing rather than straight from study.
- 4Choose a specialisation
Most investigators settle into a niche such as insurance claims, fraud, process serving, skip tracing or corporate due diligence, and short courses in open-source intelligence or interview technique help you get there. The Certified Fraud Examiner credential, run by the Association of Certified Fraud Examiners, suits people heading into fraud work and requires relevant experience.
- 5Add a degree if you want corporate or government work
A bachelor's degree in criminology, law or justice opens up government and in-house corporate investigation roles, and around 20% of people in the job hold a bachelor degree as their highest qualification. It is not necessary for general investigative work.
Ready to apply as a private investigator?
Whether you're working toward becoming a private investigator 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's it like being a private investigator?
The work runs in bursts: a surveillance job might mean a 5am start parked near a subject's house, followed by a week of record searches and report writing. Long stretches of watching are normal, and the value of a shift lies in what you notice and note down when something finally happens. The pressure comes from deadlines set by courts and insurers, and from the knowledge that your notes may be read out and tested later.
What people like
- You find out what actually happened. A case usually starts with a version of events someone has a stake in, and the job is to test it piece by piece until the picture holds together.
- Fieldwork and desk work in the same week. A Tuesday might be a title search, a Wednesday a round of witness interviews, and a Friday writing it all up for the client.
- You decide how to run an assignment. Once the brief is agreed, you choose where to park, when to approach a witness and what order to work through the checks, and the supervisor reviews the report rather than your movements.
- Several industries buy the work. Law firms, insurers, employers and government agencies all commission investigations, so there is somewhere to look when one sector slows down.
What people find hard
- Long waits before anything happens. Surveillance can be hours of a quiet street before a short, decisive moment, and you cannot leave until the subject stops moving.
- Nights, weekends and early starts. Subjects move when they move, so shifts fall outside standard office hours and plans change at short notice.
- Your reports can be challenged. A surveillance log or statement may end up in a hearing, where a gap, an assumption or an unclear timestamp can be picked apart.
- Legal limits on what you can do. No special powers come with the licence, so an approach that looks like trespass, harassment or an unlawful recording can end the case and put the licence at risk.

Will AI replace private investigators?
AI exposure in this job is moderate, and it sits mostly on the desk side of the work. Records and open-source searches, report drafting and case management all use software that speeds up the paperwork, but surveillance and interviews still depend on an investigator being present and reading the situation. The licence, the legal boundaries and the need for evidence that survives cross-examination keep the field work largely human.

Common questions about becoming a private investigator
Straight answers to the questions people ask most.
How much do private investigators earn?
Private investigators earn a median of $78,000 per year before tax for full-time work. Pay moves with the sector, your licence class and how much night or weekend surveillance you take on, since those shifts usually attract loadings. Investigators running their own agency or working as sole traders bill by the hour, so their income depends on keeping work on the books.
How do you become a private investigator in Australia?
Most people complete a Certificate III in Investigative Services (CPP30619), then apply for a licence from their state or territory regulator, which also runs a police check. From there you build supervised casework with an agency, insurer or law firm, and plenty of entrants come across from insurance claims, security or legal support.
Are private investigators in demand in Australia?
Private investigators are currently not in shortage, and employment in the occupation is projected to grow 4% over the decade to 2035. With about 500 people working in the field, the number of new roles each year is small, so openings tend to follow turnover and the hiring plans of insurers, law firms and government agencies.
Will AI replace private investigators?
It is reshaping the desk side of the job rather than replacing the work itself. Records and open-source searches now run through platforms that scan social media, court registers and commercial databases in minutes, and drafting tools can produce a first version of a report. Surveillance, interviews and the judgement about whether a piece of evidence is genuine still need an investigator on the ground.
What can a private investigator move into?
Insurance investigation and fraud investigation are the closest moves, since both use the same interviewing and evidence handling, and they pay about $13,000 more and $9,400 more. Compliance officer work pays about $9,400 more and leans on regulatory frameworks more than fieldwork, while court registrar is a lower-paid move at $19,800 less where case management skills carry across with minimal retraining. Many investigators eventually run their own agency or work as sole traders, which is often where earnings grow.
Do you need a licence to work as a private investigator?
In most states and territories you need an investigator licence before you can work for clients, and the regulator is usually the police or the fair trading agency. Requirements vary by jurisdiction, but most ask for a relevant qualification, a police check and sometimes supervised experience. Check your own state's conditions before you enrol in a course, because the licence rules shape the training you need.
