Why hire a Private Investigator? 

A loose definition of a private investigator is a freelance private detective who works for private clients. Australian private investigators are not government law enforcement employees; however, they may from time to time work for government agencies in an outsourced capacity.

  

It is unlawful for an individual to conduct covert surveillance in Australia unless they hold a valid security licence authorising them to conduct private investigations. AOSG provides affordable private investigation and surveillance solutions that are targeted, intelligence driven and tailored to your needs. That is why people choose AOSG to help them with their private investigations in Australia. AOSG's Australian private investigation team are highly experienced licensed private investigators with the skills and capacity to conduct covert surveillance and private investigations professionally and discreetly with our client's best interests in mind.

Reviews

"I can’t speak highly enough of the work of the team at AOSG. Timely, professional and discrete. One of the best going around!"

T.S ~ Legal, Sunshine Coast

“As a self-represented litigant in a protracted legal proceeding, I engaged AOSG for surveillance and documentation to accurately refute specific inaccuracies by the other party. The team at AOSG were able to quickly grasp my requirements, provide me with a reasonable quote and update me as they proceeded. The subsequent report was concise, the investigator was available to the courts for cross examination and I appreciated their knowledge, speed, accuracy, and professionalism”

L.M ~ Sunshine Coast

"The team at AOSG were extremely helpful in assisting a client involved in a protracted and complicated family law matter. As a corporate investigation company with a focus on international investigations and the travel insurance sector, AOSG provide a client-focused approach to their service delivery. We found AOSG to be professional and that they take all of their matters very seriously. We are very appreciative of their recent support and there surveillance work assisted in practically giving evidence to the Judge that was able to be viewed in the court room."
