'Private detective' and 'private investigator' are both terms that are used to refer to licensed professionals whose job is to collect evidence and conduct investigations on behalf of their clients. Some people use the term private detective to only refer to a private investigator who previously worked as a detective with police while others use the two terms interchangeably. So, there's no precise definition.

When something doesn't feel right, it can be difficult to ignore the sense that there's more to the situation. If you'd like to gain clarity, resolve a business dispute or gather admissible evidence for your personal court case, hiring a private investigator in Sydney might be the best next step.
One of our clients, a successful businessman from interstate, suspected something was going on with his partner in Sydney, so he engaged Lyonswood Investigations to learn the truth.
Our private detective in Sydney placed the female under surveillance to see what she got up to when her partner, our client, was out of town. On the first morning of surveillance, we established that she was in a relationship with another man. However, we also discovered that she and her partner had committed a number of serious property crimes with her boyfriend, and they used the proceeds to purchase illegal drugs.
We also followed the female to court, where our private investigator in Sydney saw her defending separate criminal charges, which our client was unaware of. Furthermore, our client had been supporting the woman financially as she had reportedly been dealing with a serious illness. Our investigations revealed that the illness was a lie.
As this case study shows, wrongdoing is often a pattern of behaviour, and if your intuition tells you that something is wrong, you're usually right. If you're involved with a partner, employee, competitor, regulator, family member, litigant, or organisation who you believe is engaging in dishonest or illegal activity, speak to one of our private investigators.
