The law and procedure around workplace investigations is complex and requires specialist skills and analysis to meet the legal and administrative requirements of courts, the Fair Work Commission, or the relevant Industrial Relations tribunals.

"Between the high dedication to communication and comprehensive in-depth units with good feedback, PICA has helped a lot in my development in and out of the course, and I heartily recommend it to anyone I know interested in studying Private Investigation."

Emma Goulston

“I chose PICA above all other colleges to study with because of the attention to detail the admin staff gave me and nothing was a problem. My accessor gave positive feedback and assessed each work literally the same day. Constructive feedback was vital to get the best understanding of the course and this was brilliantly delivered. I would highly recommend PICA and know you will be in good hands to competently complete your course. If you are looking for the best people to study with you have found them.”

“Cert. 3 in Investigative Services was such an interesting and engaging course. I had wanted to enrol in the course for a long time and I am happy I finally did. I learnt so much from locating a subject, the types of surveillance to writing reports. Plus, any time I was unsure or had trouble with something, I had the help of my tutor Paul, who was always super helpful. I feel more confident in investigative services and definitely recommend this course to whoever wants to start exploring in this field of work.”

John Butler

"I was apprehensive about doing a course online, but when I started the Certificate 3 in Investigative Services provided by Professional Investigators College of Australasia, I was met with great support and easy to understand student material. The course is structured in such a way that you incrementally gain knowledge to confidently move on to the next study modules. I highly recommend PICA training to anyone wanting to complete this course online."


“I would just like to say a huge thank you to everyone that supported me during the final days of securing my qualification. I did lose sight and faith in myself that I could actually finish. I appreciate everything you guys have done to support me to make sure I finished. I could not have done it without all of the support. Thanks again 🙂 I will do PICA proud with my new found knowledge in the area of my expertise that will benefit from the skills and knowledge I have accomplished. Cheers to you all and thanks again."

“I attended the intensive cert 3 course last year. I had been struggling with the solo study, but the 5 day course assisted me immensely. Within two months of attending the intensive course, I had completed my certificate. Thanks to the assistance it gave me, I am now certified as a private investigator. Paul and Greg made the course understandable with their hands on approach to the subjects. Assistance was easily sought and I cannot recommend this intensive course enough for anyone wanting to fast track their entry into the investigative industry.”
