The Questioning Partner
Something has changed - unexplained absences, a guarded phone, distance. You need to know the truth before you can decide what comes next.
Infidelity Investigation Services | Private Investigator Australia
Suspicion is painful. Uncertainty is worse. Our discreet investigators provide documented evidence so you can make decisions with clarity and confidence.
Living with suspicion about a partner's fidelity is one of the most emotionally exhausting experiences a person can endure. You deserve the truth - and the ability to make informed decisions about your life. Stirling Investigations conducts discreet, professional infidelity investigations using covert surveillance, digital footprint analysis, and background verification. Our investigators are trained to handle these sensitive cases with the utmost confidentiality and care.
We understand the emotional weight of what you're going through. We document partner movements, meetings, and activities through timestamped photography and video. Our reports provide clear, factual evidence - free from ambiguity or speculation. Whether your findings confirm your concerns or provide the reassurance you were hoping for, you'll have the clarity you need to move forward.
Important: In Australia, infidelity evidence cannot be used as grounds in divorce proceedings. However, it can be relevant to financial settlement negotiations and custody arrangements, and most clients simply need the truth to make the right decision for themselves and their family.

Book Your Free ConsultationNo. Australia operates a no-fault divorce system - infidelity is not a ground for divorce. However, evidence of a partner's behaviour can be relevant to financial settlements (particularly where marital funds were used on a third party) and to custody proceedings where the behaviour affects child welfare.
Extremely. We use unmarked vehicles, plain-clothes investigators, and maintain strict information security. Your case is known only to those directly working on it. We will never approach the subject or reveal your identity.
That outcome is more common than people expect, and it's a valid and valuable result. If our investigation finds no evidence of infidelity, we document that clearly - giving you confidence that your concerns were unfounded. Many clients find this the most important outcome of all.
Most investigations run 2--5 days of surveillance across key activity windows. Complex cases may require longer. We advise the most targeted approach to minimise cost and maximise results.
We recommend speaking with a family lawyer before and after the investigation if separation or custody is likely. We can provide referrals to specialist family law firms. Our reports are written to evidentiary standards.
Surveillance of individuals in public spaces is legal in Australia when conducted by a licensed investigator. We operate within all applicable laws and will advise you immediately if any request falls outside legal parameters.
Our core investigative method - discreet observation with documented evidence.

Claire, a 47-year-old Sydney professional, had noticed unexplained absences and significant changes in her husband's behaviour over several months. After a four-day surveillance operation tracking his movements during claimed "work functions", our investigators documented repeated meetings with a third party at a city hotel. The timestamped photographic evidence gave Claire the clarity she needed to consult her lawyer and begin separation proceedings - with full confidence in her decision and a clear picture of the financial implications.
