Hire a Private Investigator in Australia

People hire a private investigator when they need facts they can rely on, not a hunch. The brief might be an insurance claim that does not add up, a person who needs to be located, a workplace integrity concern, or evidence a solicitor can review. A licensed firm should tell you, before any field work starts, whether the job can be done lawfully and what it will take.

This guide explains how to hire a private investigator in Australia: what to check, how a proper brief is scoped, what affects the fee, and what a useful report looks like. ProFact has taken instructions nationally since 2012. If you already know the matter and the city, you can submit a brief and a senior investigator will tell you whether we can assist.

When should you hire a private investigator?

An investigator is the right next step when ordinary enquiries have stalled and the answer matters. Insurers instruct us to test what a claimant says they can and cannot do. Law firms instruct us to locate a witness, build a chronology, or observe conduct that is relevant to a dispute. Employers and corporate clients instruct us on integrity, conflicts and unexplained loss. Private clients instruct us when a family, property or personal matter needs lawful, documented enquiry rather than guesswork.

You do not need a finished theory before you call. You do need a question. “Is this claim consistent with what we are seeing?” is a brief. “Follow them and see what happens” is not. A senior investigator should narrow the question, say what can be answered, and decline work that cannot be done lawfully.

What hiring a private investigator involves

A professional instruction has four parts.

• Intake. You describe the concern, the people or places involved, any deadline, and what a useful answer would change.
• Scope. The investigator confirms the methods that are lawful for that jurisdiction, the steps required, and what will not be attempted.
• Written terms. Fees, timing, reporting and confidentiality are agreed before deployment. Field work should not start on a verbal nod.
• Report. Findings are dated, sourced and separated from opinion, so a claims handler, solicitor or decision-maker can use them.

Common work includes surveillance, factual inquiry, locate and welfare checks, background screening, and desktop research. Some matters stay at the desk. Others need field investigators. The scope should say which, and why.

Check licensing before you hire a private investigator

Licensing is state and territory based. New South Wales, Victoria, Queensland and several other jurisdictions require an appropriate security or inquiry-agent licence before someone can undertake investigation work. The ACT does not run a standalone private investigator licence, but the activity still has to comply with privacy, surveillance and evidence laws, and cross-border work into NSW has to meet NSW requirements.

Ask for the licence name and number, and check it on the public register for that state. ProFact’s national practice operates under NSW Security Master Licence #000111294, expiry 6 July 2027. Investigators deployed interstate work within that framework and the local rules that apply to the place where the work happens.

Questions to ask before you instruct

1. Who will review the brief, and will that person stay responsible for the file?
2. Which licence covers the work, and in which state or territory will it be done?
3. What methods will be used, and which methods are off the table?
4. What will the report contain, and who else will see it?
5. How are fees structured if the matter runs longer, or finishes early?
6. What happens if the objective cannot be met?

You should get plain answers. A firm that will not explain licensing, confidentiality or the difference between a locate and a week of surveillance is not ready to take the instruction.

How ProFact scopes a brief

A senior investigator reads the enquiry first. If we cannot lawfully help, we say so. If we can, we confirm the objective, the geography, the urgency and the reporting format, then issue written terms. There is no charge for that initial discussion.

Surveillance, locate work and desktop inquiry are scoped differently because they use different time, travel and reporting. A single address in inner Melbourne is not the same file as a Northern Territory deployment or a multi-day surveillance across Sydney. The quotation should show that, not hide it in a day rate.

What it costs to hire a private investigator

Fees follow the work. A desktop check or a single-person locate starts lower than two-operative surveillance or a file that needs travel and a court-ready chronology. Indicative Australian starting points are on the private investigator cost calculator. The longer explanation of what moves a quote up or down is in how much a private investigator costs in Australia.

Treat both as guides. The figure you should rely on is the written quotation for your brief, issued before anyone is deployed. Ask what is included, what would be an extra, and what happens if the objective is met on the first day.

What you should receive in the report

A report is useful when someone who was not on the file can follow it. Dates, times and places should be clear. Observations should be separated from inference. Limits should be stated: if a subject was not seen, or a record could not be checked, the report should say so. Media and notes should be retained so the author can explain the work later if a solicitor, insurer or court asks.

Investigators are not advocates. Their job is to report what the agreed scope asked them to examine. If the material may be used in proceedings, that should be known at scoping, not after the report is written.

Where to hire a private investigator in Australia

ProFact takes instructions nationally, with senior review on every file. Local pages explain how briefs are handled in each city:

• Private investigator in Sydney, from the Ultimo head office, for NSW and ACT work.
• Private investigator in Melbourne, for Victoria and Tasmania.
• Private investigator in Brisbane, for Queensland and the Northern Territory.
• Private investigator in Canberra, including matters that cross into nearby NSW.

The full capability list is on the services page. If your matter does not sit neatly in one city, say so at intake. Travel and the licence that applies are part of the scope, not an afterthought.

What a private investigator will not do

Hiring an investigator is not a way around the law. A competent firm will refuse to hack a phone, enter property without authority, fit a tracker without a lawful basis, or obtain records they are not entitled to see. They will also refuse a brief that is really about harassment, or about finding a private address so someone else can confront a person.

If the objective cannot be met lawfully, the right outcome of the first call is a decline. That protects you as well as the firm.

Frequently asked questions

How quickly can I hire a private investigator?

Urgent files can often be reviewed the same day. Deployment depends on the city, the method and whether written terms are accepted. Regional and interstate work needs more lead time than an inner-suburban instruction.

Do I have to meet in person?

No. Most briefs start by phone, email or the online form. Meetings at the Sydney, Melbourne, Brisbane and Canberra offices are by appointment once a senior investigator has confirmed we can assist.

Will the investigation stay confidential?

Client identity, the brief and the findings are not shared except on your instruction or where the law requires it. Reporting channels are agreed before work starts.

Can the report be used in court?

Lawfully obtained material can support a legal file. Whether it is admissible depends on how it was gathered and the rules of that court or tribunal. ProFact does not give legal advice on admissibility. If court use is likely, say so when you brief us.
