Why hire John W. Pettit?


Do you currently have a matter that needs the expertise of a suitably experienced and tertiary qualified security expert & consultant? Well look no further. I have over 35 years of security industry experience and hold tertiary degrees in Security, Criminology and Work, Health & Safety (with a Specialisation in Occupational Safety).

Since 2009, I have been in private practice as a security expert witness and security consultant accepting instructions for the preparation of security-legal reports from law firms from around Australia in relation to security negligence and liability. I am happy to take ‘no obligation’ calls at any time from practicing staff seeking preliminary advice on prospective cases involving security negligence.

Need Help Obtaining Evidence?

The success of all cases hinges on the ability to obtain evidence of sufficient evidentiary weight to support or prove the allegations of negligence on the part of the defendant. With my extensive experience acting as a Security Consultant, Security Expert and Expert Witness, I can assist legal practitioners to identify potential sources of evidence that they might not otherwise have considered or been aware of. For your client, being able to obtain the right evidence of sufficient evidentiary weight can mean the difference between winning or losing their case.

Need an Expert in a Specific Area of Security?

As a tertiary qualified security professional with over 35 years of industry experience, I have reviewed literally hundreds of cases involving security negligence and liability since commencing in private practice in 2009 as a security consultant, security expert and expert witness. Listed below is a summary of my forensic casework in which I have acted in the capacity of a security expert and expert witness.

    I am pleased to provide this testimonial on behalf of Mr John Pettit, Forensic Security Consultant. John was recently retained by my firm to provide a forensic security report in respect to a personal injuries matter that I was involved in before the Supreme Court of NSW. It was refreshing to finally find a security expert who not only had experience, but had relevant formal tertiary qualifications in Security, Criminology and Occupational Health & Safety in order to be able to truly qualify themselves as an expert witness in the field of security. John’s understanding of the legal process was also evident in the manner in which he prepared and structured his reports. I have no hesitation in recommending John as a competent expert witness in the field of security to any other legal practitioner.

    I was singularly impressed with the report provided by John Pettit for use in a matter I was personally involved with, while appearing before the Australian Family Court. The report was of such quality and substance that the opposing legal team were at a loss as to how to respond, deny, refute, or challenge its content.  It was one of the best and most effective and comprehensive expert witness reports that I have seen in over twenty years of legal practice. It is now without reservation or hesitate that I recommend John Pettit to other legal practitioners seeking an expert witness in the discipline of Security Management.
