What drives private investigator cost?
Indicative figures are a starting point. The final investment depends on how much time, expertise, travel and reporting your brief requires once it has been scoped properly.
What affects the final fee
No two briefs cost the same. Even where the investigation type is similar, the investment required can change materially once scope is understood. Common drivers include:
- Scope and objectives. A single verify check is priced differently to a multi-subject inquiry or sustained surveillance.
- Field time and operatives. Half-day and full-day blocks, second operatives, and multiple days all change the total.
- Location and travel. Metro deployment is different to regional or remote work, especially where travel exceeds included allowances.
- Urgency. Rush deployment, after-hours work, or tight court dates can require additional resources.
- Reporting and legal requirements. Chronologies, statements, expert-ready reporting and court attendance add time and cost.
- Third-party disbursements. Database searches and specialist reports may be charged at cost plus an agreed margin where applicable.

Private investigator cost FAQs
How much does a private investigator cost in Australia?
There is no single answer. Simple desktop or locate matters may start from lower budgets, while sustained surveillance, multi-party inquiries or forensic work can run to several thousand dollars or more. The calculator above provides indicative guides only. ProFact confirms scope and provides written terms before work begins.
Why do two investigations of the same type cost different amounts?
Investigations deal with the unknown. Subject behaviour, location, availability of records, number of operatives required, reporting depth and urgency all change the work required. That is why we scope every brief individually rather than publishing fixed fees.
Does the calculator show ProFact's exact fees?
No. The tool shows broad indicative guides for common investigation types in Australia. It is designed to help you understand typical starting points, not to quote a final fee. A senior investigator reviews your brief and issues written terms before any work starts.
What is usually included in a surveillance fee?
Typical flat-fee surveillance blocks include field time within the booked period, travel up to an agreed distance, case management, reporting and handling of footage where taken. Administration, extra travel, additional operatives or extra days are scoped separately where required.
Do I pay for an initial consultation?
Consultation and file setup are commonly charged as a separate initial engagement. At ProFact, consult time is often transferable if you proceed with further work under agreed written terms. The calculator includes indicative consultation guides for general and complex matters.
Are search fees and expert reports extra?
They can be. Third-party database searches, specialist forensic analysis, handwriting or audio experts, and court attendance may sit outside a basic field or research budget. Where disbursements apply, they are usually explained in your written scope.
How do I get an accurate quote?
Submit a brief with as much detail as you can: what you need established, relevant dates, locations, subjects and any deadline. A senior investigator will review capability, confirm scope and provide written terms before work begins. You can contact ProFact online or call 1300 464 810.
Can investigation costs vary by state?
Yes. Travel, licensing context, subject location and the amount of field time required can all differ between metro, regional and interstate briefs. ProFact operates nationally and scopes each matter on its facts rather than applying a single national flat fee.
Need a scoped quote for your brief?
Submit your matter confidentially. A senior investigator will review capability, confirm scope and provide written terms before work begins.
