With over 49 years’ experience, our organisation understands the need for the utmost discretion when it comes to private investigations, which may involve surveillance on a partner or spouse, troubled teenagers, or missing persons enquiries.

Importantly, for your convenience, we operate 24 hours a day, 7 days a week, and therefore have the capability to handle urgent assignments whenever they arise. Our Surveillance Investigators are experienced and fully licensed to ensure the right results are achieved.

This type of investigation can be particularly sensitive and accordingly, you need to engage a reputable, licensed Investigation Company that you can trust to carry out the investigation in a discreet, effective and lawful fashion.

Having been in operation since 1972, you can have absolute peace of mind that the Cox Group will professionally and sensitively service all of your requirements in any private investigation.

In all types of claims, factual investigations play a very important role in establishing the facts and circumstances surrounding the event in question.

One of the crucial issues of factual investigations is the taking of competent statements that provide all necessary information, enabling Insurers and their legal advisers to make important decisions in relation to liability.

Of course, the key ingredient of a competent statement is the careful preparation of questions to be asked of a person during an interview.

In this respect, it should be noted that our Principal, Mr Peter Cox, is a former Senior Detective with the New South Wales Police Service who has extensive experience in the areas of major crime and Scientific Police investigation.

In 1990, at the joint request of the California Department of Justice, Department of Treasury and the Bureau of Alcohol, Tobacco and Firearms, he presented a paper concerning “Investigative Statement Taking” to the International Association of Forensic Sciences. Details of the paper have since been sought by the Home Office, London and the Forensic Division of the Training and Standards Branch, Australian Federal Police.

We offer both Narrative Statements and Digitally Recorded Interviews, whichever a Client may prefer. Computer generated sketch plans, photographs and comprehensive, but concise, reports are all provided in a professional and cost effective manner.


Personal Injury claims often require surveillance to determine the veracity or otherwise of a claim. We have conducted surveillance in relation to a range of Personal Injury claims over the past 49 years, primarily concerning Compulsory Third Party, Public Liability, Income Protection and Workers’ Compensation. We have also carried out surveillance in domestic and sensitive industrial assignments, together with Government work.

Our Principals, Managers and many senior Surveillance staff have a wealth of experience in discreetly observing Subjects, of which we are required to obtain video and photographs.

Surveillance investigations have formed a significant part of our revenue over the past 49 years and therefore, we have been committed to ensuring that our Investigators perform consistently to a high standard.

We are acutely aware of our responsibilities with surveillance concerning privacy and security of information. We are also very conscious of ensuring we report our findings in a professional and unbiased manner.

If, for example, a Claimant appears genuinely restricted, we will certainly not fully utilize the allocated hours on that particular job.

On the other hand, if a Claimant is particularly active and his activities are contradictory to his claims of incapacity, we may liaise with Claims staff and seek additional hours, particularly in order to obtain video evidence over consecutive days.

Whilst experienced Investigators and competent management are essential, it is also important to have suitable equipment and in this regard we use the most advanced cameras available, resulting in unrivalled video quality.
