Scared of eavesdropping or private conversations being recorded? Fret not.

When you suspect your partner of cheating, there is an immediate need to substantiate your doubts. If you act on your instincts and confront your partner without any proof, there is a possibility that your relationship may fail on account of wrongly accusing your spouse. Also, your partner may find a fake alibi and get himself/herself out of the testing situation without being caught. Since a lot is at stake in a family matter, you cannot afford to take chances. With our qualified and experienced private investigators in Melbourne, you can be rest assured about finding the truth without any delay. Our detectives are skilled in obtaining photo/video evidence, tracking down vehicles, obtaining records. We are fully licensed to perform these procedures and act with absolute discretion.
The amount of anxiousness and fear that crops up in one’s mind when a loved one goes missing cannot be explained in words. As is the case when someone who owes you money or has committed some fraud is absconding. Both situations lead to sleepless nights thinking about the person and running from pillar to post to find them. With the help of our sharp-witted and quick private investigators in Melbourne, it becomes possible to know the whereabouts of these missing people. It may take some time, but we do not leave the investigations midway and we actively use our contacts and networking to follow leads in identifying where the person maybe in any part of the world. Sometimes the missing person may not want to be found. In such cases, we respect their privacy and offer closure to the family.
With the crime rate rising at an unprecedented rate, it has become more than necessary to take care of your loved ones and your personal belongings. Security is an essential service that can save you from untoward situations and give you the ability to alert the authorities in time to avert any danger. OJT Investigations Group offers unmatched security services which are executed by trained professionals, primarily ex-military and retired members of the Special Forces.

We are well-versed in interviewing and statement taking. Our ability to read between the lines and get the truth out of the witnesses through a causal question answer round is exemplary. We taek pride in conducting the most result-driven interviews that help clients in gaining access to information which can turn the direction of their civil or criminal case.

The areas that we specialise in include harassment statements, traffic accident statements, minor theft statements, child custody statements, work accident statements, insurance statements and more. The statement is taken by our qualified expert and Justice of the Peace, so there is no question that the matter won’t be handled properly.
Gone are the days when surveillance meant following a person or a vehicle from a distance. With changing times, the rules of the game have also changed. The digital era calls for the use of more sophisticated equipment and techniques to unravel the truth.

Our private investigators in Melbourne provide excellent surveillance service using the best technology that acts as a verifiable testimony in court proceedings. Whether it is a domestic dispute or corporate data theft case, we carry out covert surveillance operations to detect potential threats and get answers to all your questions without fail.
