Why hire a Private Investigator? 

A loose definition of a private investigator is a freelance private detective who works for private clients.  Our Brisbane 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 in Brisbane, the Sunshine Coast and on the Gold Coast that are targeted, intelligence driven and tailored to your needs. That is why people across Australia and overseas choose AOSG to help them with their private investigations. AOSG's Sunshine Coast, Gold Coast and Brisbane 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.

“I suspected there was a breach of one of my social media accounts. I contacted AOSG and their cyber security team was able to fix my problem. Although it was small, they treated my case as a high priority. Thank you! I would recommend AOSG for any social media or cyber security issues”

"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

"While I was going through a horrendous domestic violence and family court battle, AOSG were there to help. Their surveillance teams uncovered critical information and a comprehensive report of their findings was presented in court. When it came to the family court hearings, AOSG even provided my family and I bodyguards to protect us. They were so organised and professional I felt safe and protected the entire time.  I cannot thank the AOSG team enough for their continued dedication and commitment over the last two years in support of my case. I would highly recommend the services of AOSG to anyone needing surveillance or security. Thank you!"

T ~ 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."
