Infidelity Investigator Australia- Private Detective for Cheating
Licensed private investigators who confirm or rule out suspected infidelity with documented evidence. Confidential, legally gathered, Australia-wide.
A licensed infidelity investigator uses lawful surveillance, background checks, and evidence collection, photos, video, and activity logs, to confirm or rule out a suspected affair. What’s legal differs by state, since each state licenses investigators and regulates surveillance separately. Evidence gathered lawfully can support a conversation with a family lawyer, and for de facto couples, a property claim generally has to be made within two years of separation.
What is an infidelity investigation?
An infidelity investigation is licensed surveillance and evidence collection that confirms or rules out a suspected affair using photographs, video, and documented movements, not accusations.
Instead of confronting a partner on suspicion alone, a licensed investigator documents where someone actually goes and who they actually meet, over an agreed period. The output is a factual record, not a guess, which is the difference between an argument and an answer.
How do private investigators catch a cheating partner?
Investigators observe and record a subject’s movements and meetings in public spaces, or other legally permitted locations, over an agreed period, without contact or confrontation.
A typical case starts with a planning call to understand the subject’s routine, then moves into scheduled surveillance sessions. Investigators work from unmarked vehicles, keep a discreet distance, and log times, locations, and interactions as they happen, so the final report reads as a timeline rather than a summary written from memory.
Is it legal to hire a private investigator to follow my partner in Australia?
Yes. Surveillance is legal when the investigator is licensed and only observes a person in public places, or other locations without a reasonable expectation of privacy.
What counts as legal, though, is not the same everywhere in Australia. Every state licenses private investigators separately and regulates surveillance under its own legislation, so a method that’s lawful in one state can be a breach in another.

What can a private investigator not legally do?
They cannot trespass on private property, install a tracking device without lawful authority, hack a phone or account, or record a private conversation without consent in most states.
- No entering private property, including a vehicle, without the owner’s or occupier’s consent.
- No hidden cameras in places where someone reasonably expects privacy, such as a bathroom or bedroom.
- No hacking phones, email, or social media accounts, regardless of how the evidence would be used.
- No recording a private conversation without consent, except in the specific circumstances each state’s surveillance law allows.
How much does an infidelity investigation cost?
Cost depends on hours of surveillance, the number of investigators required, and location. Australian market rates commonly fall in the range of $150 to $300 per hour.
The hourly figure above reflects publicly stated rates elsewhere in the Australian market, not AusCovert‘s own pricing. Confirm your current rate card before this goes live, then replace the flagged figure with your actual number, since a specific, accurate rate outperforms a vague “contact us for pricing” line in both search and AI answer engines.
What evidence will I actually receive?
A written report plus timestamped photographs, video footage where relevant, and a log of the subject’s movements and meetings during the surveillance period.
The report is written to stand on its own, a plain-language timeline supported by the evidence, so you’re not left interpreting raw footage yourself. If your case may end up in front of a lawyer, ask your investigator for the report in a format that includes metadata and timestamps intact.
Can the evidence be used in court or a family law matter?
Yes, if it was gathered lawfully. Courts generally accept evidence obtained without trespass or illegal recording, though weight and admissibility are decided case by case.
Lawfully gathered evidence doesn’t automatically decide a family law outcome on its own. It’s one input a solicitor weighs alongside financial records, parenting arrangements, and the couple’s specific circumstances.
What should I do after I receive the investigation report?
Treat the report as information, not a verdict. Typical next steps are a direct conversation, independent legal advice, or counselling, depending on what you want out of the relationship.
This is the step almost no infidelity investigation page covers, and it’s often the part people find hardest. A report tells you what happened. It doesn’t tell you what to do next, and that decision sits with you, not the investigator.
If you’re married or in a de facto relationship and property or separation becomes a live question, the relevant law is the Family Law Act 1975. Section 4AA defines a de facto relationship as two people living together as a couple on a genuine domestic basis, and for de facto couples specifically, a property settlement claim generally needs to be made within two years of separation, unless the court grants an exception for hardship.
Does the law treat married, de facto, and dating relationships differently?
Yes. Married and de facto couples together for two years or more can generally access the same property and maintenance rights under the Family Law Act 1975.

How long does an investigation take?
Some cases resolve in a single surveillance session. Others take several sessions across different days or weeks, since affairs rarely follow a predictable schedule.
Your investigator gives you a realistic timeframe after the initial consultation, based on the subject’s routine and how much you already know about their movements.
Will my partner find out I hired an investigator?
Licensed investigators use unmarked vehicles, secure communication, and covert methods specifically designed so the subject doesn’t notice they’re being observed.
Case details are also kept off any communication channel your partner might see, and updates are sent to you directly rather than through shared accounts or devices.
Is my consultation and case kept confidential?
Yes. Licensed investigators are bound by state licensing conditions and industry codes of conduct requiring confidentiality about your identity and case details.
Your file is not discussed outside the investigation team assigned to your case, and that obligation continues after the report is delivered.
