Private Detectives and Investigators

Group One Investigation

Group One Investigations is Melbourne’s premier investigative services agency, excelling in the field of private intelligence and surveillance for over twenty years. We provide discreet professionalism in all aspects of corporate and domestic surveillance. If you’re seeking information that has been obscured, you need an expert, and our private investigators have mastered their craft. Don’t let hesitation prevent you from accessing the expertise of a professional who can save you from the sense of regret from not having learned vital information or a valuable truth until it’s too late. Our agency is intimately acquainted with the methods and strategies that individuals will utilise in an attempt to pull the wool over your eyes. The best way to protect yourself from misinformation and to find out the truth is to hire investigators familiar with these deceptions and who have solved these cases before.

People will often attempt to obfuscate the truth, not always out of malice or spite, but sometimes simply because they feel the need to leave out details they believe will prevent them from finding success in life. Even still, it is important to exercise your due diligence in a world where small, delicate details can get lost amongst the abundance of information. Information is power, and while we wish we could all give everyone the benefit of the doubt, it is essential to separate the bad actors from the well-meaning. At Group One Investigations we pride ourselves on our professionalism and reliability. We offer cost-effective investigative solutions in a timely manner. Gaining a thorough overview of a potential client or employee’s background is essential in ensuring that your business interests are protected and can also give you peace-of-mind.

Group One Investigations are experts in surveillance, locating missing persons, intellectual property investigation and more. We offer surveillance, activity reports, undercover operations, investigating extra-marital infidelity, assisting in the safety of your teenagers, polygraph testing, email tracing and internet based investigations, uncovering fraud, employee theft and background checks, and other critical operations. Our agency focuses on results, meaning that our clients’ satisfaction is the foundation upon which we ensure we are the best private investigator agency in Melbourne. We are licensed by the Australian Government, so you can take comfort in knowing that every information gathering technique we employ is legal, and that our relationship with our clients is maintained under strict confidentiality. We are judgment-free and objective in our aims, and our private investigators will pursue every avenue and won’t give up until every option has been exhausted.

What is the first step if I want to begin an investigation?

The first best step is to contact us on 1800 181 880 or  info@grouponeinvestigations.com.au

We will then require as much information as is possible from you on the organisation, individual or debtor you are having investigated. The more information we begin with the faster we can locate them and/or secure the intended information or evidence about any given situation. This will also be helpful in reducing costs to you.

Not all cases are identical and, as such, our investigation will be tailored according to your needs. Group One Investigations exercises the utmost care and confidentiality across all sectors of our work, and we aim to deliver cost-effective private investigation while utilising only legal means of obtaining the desired knowledge.

The debugging equipment is state of the art. Additionally we have a specialist phone examiner and equipment to conduct this type of work, so you can rest easy knowing that we are at the very forefront of private investigative solutions.
