Damian Marrett

Former Victoria Police Detective Damian Marrett is a leading investigative professional. Having served as one of Victoria Police’s most successful covert operatives for many years, Damian has been involved in some of Australia’s largest undercover investigations.

Damian’s ability to infiltrate major organised crime groups and investigate major crime offences provides him with a unique and diverse understanding of the work required to source information that will lead to an outcome. It goes without saying, that operating undercover demands a need for discretion – your survival depends on it! 

Damian has worked in most Australian states and understands the individual laws and regulations governing these jurisdictions. He has also worked internationally, most notably as a drug investigation consultant, sharing his expertise with the Norwegian Police Force.

This breadth of experience means Damian has connections in the industry that are second to none.

Following his time serving with Victoria Police, Damian has continued with investigation work and is often invited to provide crime commentary for TV and radio networks as well as various other media platforms. Damian has written three non-fiction true crime novels published by Harper Collins and co-produced a true-crime series - Police Under Fire for the Seven Network. His creative and inventive nature enables him to think ‘outside the box, a necessary skill rarely seen in the Private Investigations Industry.

Damian has been featured on numerous real crime series and has worked with the leading public affairs program, 60 Minutes, appearing in a covert capacity on stories involving global scams throughout South East Asia.

Having a particular affinity with cold case investigations and searching for answers to previously unsolved mysteries – Damian’s investigative skills are comprehensive and wide-ranging. Utilising leading-edge technology and contemporary investigative techniques as well as old school detective skills, no case is too complex nor too small, and providing professional all-round service with a personal touch is what sets Marrett Investigations apart.

Whether it is corporate or domestic clients, Damian knows the importance of tailoring his service to meet your needs. Marret Investigations Australia services have been sought for cases ranging from complex to small; large organisations including schools and sporting groups; small and medium-sized businesses; and many individual personal investigations. Personal cases often involve historical locates of lost relatives and friends, as well as other people of interest.

A strong believer in crime and justice, Damian has also been a Director of Community Against Crime ( a Not-for-Profit role) over the past 10 years.
