You deserve a straight answer

Suspecting a partner of cheating is exhausting. You notice the small things, ask the questions, and get answers that don’t quite fit. You might check their phone or the bank account and still not be sure. It can take over your sleep, your work and your family life.

A private investigator replaces guessing with facts. In many cases one well-timed day of surveillance is enough. Either you see that your worries were wrong, or you have the proof you need to decide what to do next.

When it might be time to call us

• Your partner suddenly works late, travels more or has new hobbies that take them out of the house
• Their phone is never left alone, and messages get deleted
• There are hours in their day you can’t account for
• They’ve changed how they dress, or how they act towards you
• There’s spending you can’t explain
• A friend has told you something you can’t shake off

How we run a cheating partner investigation in Sydney

1. Talk to us. Call or message any time, day or night. Tell us what’s going on. Everything is kept private.
2. Plan the timing. Together we work out when your partner is most likely to be up to something. The right window makes all the difference.
3. Lock in the job. Pay the first 4-hour block and we book a licensed investigator. We’ll need a few basics, like a photo, the car and where they’ll be leaving from.
4. Surveillance across Sydney. Our investigator knows Sydney’s roads, from the CBD to the Northern Beaches, the Hills and the west. They follow from a distance in an unmarked car and record what happens.
5. Your evidence. Once the balance is paid, you receive a written report with dates, times, locations, photos and video. You can ask for updates while the job is running.

What’s in your report

• A time-stamped log of every move: where they went, how long they stayed, who they met
• Photos and video of what the investigator saw
• A clear layout that’s easy for you, or your lawyer, to follow
• The option to book more days if you need them

The kinds of cases we take

General examples, not real client stories:

• The after-work drink. A partner keeps getting home hours late from the city. We follow from the office to see where the evening really goes.
• The new “friend”. A name keeps coming up, or a contact saved under a fake name. We find out who they are meeting and how often.
• The weekend away. A trip that doesn’t sound right. We check who they’re with when they get there.
• Before you separate. You want the facts before talking to a lawyer or moving out.

Cheating partner investigator Sydney: FAQs

How much does a private investigator cost in Sydney for a cheating partner?

We charge $120 + GST per hour. Every job starts with a 4-hour block at $1,100 + GST, which covers travel time, km, admin and average expenses. Further hours are $120 + GST each.

Is it legal to have my partner followed in NSW?

Yes. It is legal to hire a licensed private investigator in NSW. Our investigators work from public places and stay within the law.

Could my partner notice they’re being followed?

Our investigators are trained to blend in, use unmarked cars and keep their distance. If they think they’ve been spotted, they back off instead of pushing on. We never contact your partner.

How quickly can you start?

We work across Sydney and are available 24 hours to take your call. Once the job is booked and paid, we arrange an investigator for the day and time you choose.

How many days will I need?

Many cases are answered in one or two days when the timing is right. If your partner’s routine is hard to predict, it can take longer. We’ll talk it through with you before you book.

What will I receive?

A written report with dates, times and places, plus photos and video. It’s sent to you once the balance is paid.

What if my partner doesn’t do anything suspicious?

You still receive a full report showing where your partner went. For many people that brings real peace of mind. If you’re still worried, we can help you plan another day at a better time.

Can I get updates during the surveillance?

Yes. Ask when you book and we can keep you updated during the job.

Will the evidence help in a divorce?

Australia has no-fault divorce, so an affair doesn’t change how property is divided. Most clients want the truth to make their own decisions. Evidence can still matter in some family matters, like who is living in the home with your children. Our reports are dated, timed and clear, so your lawyer can use them. Ask your lawyer about your own case.

What information do you need?

Usually a recent photo, the car and number plate, the starting address, and the day and time you’re concerned about. We only ask for what the job needs.

Do you cover all of Sydney?

Yes. We cover the whole Sydney area, including the CBD, Eastern Suburbs, North Shore, Northern Beaches, Hills District, Parramatta, Western Sydney and the south.

Is my call confidential?

Completely. Your details are never shared, and your partner is never contacted.
