It's one of the first questions people ask — and one of the hardest to answer without knowing the specifics. Private investigator costs in Sydney vary significantly depending on the type of investigation, how long it takes, and the complexity involved.
This guide gives you realistic figures and helps you understand what you're actually paying for.
The honest answer on pricing
There's no fixed rate card for private investigation work in Australia. Any PI who quotes you a flat fee before understanding your situation is either cutting corners or guessing. Good investigation work is scoped to the specific situation — and so is the pricing.
What we can tell you is the typical range for common types of work in Sydney:
| Type of investigation | Typical starting range |
|---|---|
| Background check (individual) | From $300–$600 |
| Background check (business/entity) | From $500–$1,200 |
| Surveillance (per day) | From $800–$1,500+ |
| Pre-employment investigation | From $500–$1,500+ |
| Missing persons / location | From $400–$1,000+ |
| Due diligence (corporate) | From $1,000–$3,000+ |
These are indicative starting ranges only. Your actual cost will depend on the specific scope agreed before work begins.
At Fortis Analytica, all fees are agreed in writing before any work starts. You will never receive a surprise invoice. If the scope needs to change, we discuss it with you first.
What affects the cost?
Type of investigation
A simple background check on an individual using open sources takes a few hours. A covert surveillance operation that spans multiple days and locations takes significantly more time and resources. The nature of the work is the biggest driver of cost.
Time and complexity
Investigations that involve subjects who are difficult to locate, frequently change location, or require extended monitoring naturally take longer — and cost more. We can't always predict this upfront, which is why we scope engagements carefully and discuss any changes with you before proceeding.
Travel and expenses
Surveillance work across Greater Sydney — from Parramatta to the Eastern Suburbs, North Shore to the CBD — involves travel time and expenses. These are factored into the scope or charged at cost, and always disclosed upfront.
Report requirements
If you need a detailed written report — particularly one prepared for use in court proceedings, insurance claims, or internal HR processes — this adds to the overall cost. A court-ready report takes more time to prepare than a verbal briefing.
Is it worth the cost?
That depends entirely on what's at stake. For someone making a major hiring decision for a sensitive role, spending $800 on a thorough pre-employment investigation is a fraction of the cost of a bad hire. For a business considering a significant commercial partnership, a due diligence investigation could save far more than it costs.
For personal matters — particularly those that may involve legal proceedings — having professionally gathered, court-admissible evidence is often the difference between a case that succeeds and one that doesn't.
What you should watch out for
Unfortunately, like any industry, private investigation has operators at the lower end who cut corners. Be cautious of:
- PIs who can't provide a licence number — unlicensed operation is illegal in NSW
- Unusually low flat-rate quotes before any discussion of your situation
- No written agreement before work starts
- Promises to obtain information through means that sound unlawful
- No clear explanation of what methods will be used
Cheap investigation that produces unusable or unlawfully obtained evidence is not a bargain — it's a waste of money and potentially a legal problem.
