Cheating partner & infidelity investigations

Suspect your partner is cheating? Start with the facts.

If you suspect a partner is cheating, we can assess discreet factual enquiries and surveillance options across Australia, including Brisbane, Sydney and Melbourne. We start with a confidential conversation, agree the scope and costs, and report what the evidence supports without promising a particular finding.

Start with a short enquiry. We assess suitability and agree the scope and price before payment.

Does this feel familiar?

When uncertainty is changing how you live.

Plans and explanations have changed, and the uncertainty is affecting what you do next.

What we can clarify

We assess whether a defined factual enquiry or observation period is proportionate, then report what occurred without assuming a conclusion.

Discuss an infidelity enquiry

Your first message can be brief. Choose how we can reply safely. We will explain whether this service fits before asking for documents or payment.

Unsure whether surveillance is needed?

When this may help

  • You need facts before making a relationship decision.
  • You want to understand suitable desktop or field options.
  • You need clear reporting rather than assumptions.

What you receive

  • A confidential suitability and scope assessment
  • Agreed factual enquiries and proportionate reporting
  • Written findings and available relevant media for field work

A considered approach

We do not hack devices, access private accounts, trespass or guarantee evidence of infidelity. Field availability and final pricing depend on the location and scope.

What to prepare

Start with a short chronology, the general location and the question you need answered. Tell us when and how it is safe to reply. Relevant details and existing documents can be requested through the client portal after assessment.

Agree the scope before payment

PartnerCheck is licensed to provide investigation services across Australia. Field enquiries are assessed nationally, subject to investigator availability. We agree observation time, travel, reporting and any extra-work approval before payment. Suspected infidelity is a question to investigate, not an assumed conclusion.

Prepare a confidential investigation brief

Before you decide

Answers to the questions that shape your brief.

Do you offer infidelity investigations in Sydney and Melbourne?

Yes. We assess Sydney and Melbourne enquiries and have appropriately licensed local investigators available for suitable surveillance and fieldwork. Start with the location, relevant timing and question you need answered. We confirm investigator availability, observation time, travel, reporting and total cost in your written scope before payment. An enquiry does not guarantee a particular finding.

Can you investigate a suspected cheating partner?

We assess the specific question, relevant locations and information already available. Suitable work may involve factual desktop enquiries or scoped surveillance across Australia, including Brisbane, Sydney and Melbourne. Suspicion alone is not evidence and we do not promise a finding of infidelity.

What is included in a surveillance price?

The package above states its included time and reporting. Before payment, we confirm the location, timing, travel and any additional costs in your written scope. Extra work requires your approval. Unused time and cancellation are handled under the agreed service terms.

What happens if the person is not observed?

The report records the work undertaken, observations and practical limitations. A surveillance period may produce no contact or usable footage. We discuss any proposed further enquiries and their cost before proceeding.

How can I make a discreet enquiry?
