Dennis Hart

Dennis Hart

Dennis Hart arrived in Darwin in 1969 and worked in the automotive industry until 1972, when he joined the Northern Territory Police Force as a public servant.
Immediately after Cyclone Tracey Dennis commenced his police training in Adelaide. Dennis remained with the police for over 20 years; serving a short time in uniform before being transferred into the Criminal Investigation Branch. Over the ensuing years Dennis attained the rank of A/Superintendent and was either the lead or support investigator in a number of high profile Northern Territory cases involving drug plantations, murder, fraud and major crime investigations. After spending a number of years in the drug squad, Dennis was made Officer in Charge of that unit and then later went on to become the Officer in Charge of the Criminal Investigation Branch.
For the last 21 years Dennis has been employed by Paspaley Pearling Coy as their Security Manager. During that time Dennis has travelled extensively across the world either coordinating major pearl auctions, providing safe-hand delivery for pearls, or accompanying the company principals on major business trips. In more recent times Dennis has turned his hand to research and has been working on a project to deliver exotic pearl meat to restaurants globally. This has involved extensive consultation with a range of stakeholders including company directors, scientists, DFAT and other businesses that have achieved export and supply chain accreditation for other seafoods.
Now that his overseas travel is down to three or four trips a year Dennis is looking forward to contributing to the NT community through Crime Stoppers Northern Territory.
In his spare time Dennis enjoys fishing the Peron Islands with his two daughters and wife and dabbles in carpentry, welding, mechanical repairs and basically anything that needs fixing!
