Professional Infidelity Investigations in Sydney
With over 40 years of experience as private investigators in Sydney, our team can help you uncover the truth discreetly. Having worked on thousands of cheating partner cases, we have seen how important it is to get undeniable proof. This evidence is important not only for your own peace of mind but also can be important if the cheater lies after a separation (which is common) and you need to convince family or friends that you were not the person at fault.
If you’re considering a commitment instead, our marriage background check can offer insights before you take that significant step.

Infidelity Investigations in Sydney FAQs
Our infidelity investigations in Sydney provide various forms of evidence depending on the case specifics, including photographic and video evidence as well as detailed reports on the activities of the subject person.
The duration of infidelity investigations in Sydney varies based on the complexity of the case and the amount of information needed. Some investigations are easily concluded within a few hours, while others take longer as we carefully gather evidence.
Evidence of infidelity is not relevant for court proceedings in Australia but evidence gathered during an investigation may be relevant in other respects, for example in custody or settlement hearings. The cheater’s new partner may be wealthy or may have a serious criminal record and these are factors that can affect the outcome of the care of your children or the division of your assets in a split.
