Robert Redenbach spent six years in the Australian Defence Force before pursuing a career in the security industry. He has studied martial arts extensively throughout Asia, managed a security company in Papua New Guinea and between 1994 and 1998 he lived in South Africa where he was a senior defensive tactics instructor of Nelson Mandela's Presidential Protection Unit. He has lectured as a guest speaker at the FBI Academy at Quantico, Virginia, provided unarmed combat training to British and European Special Forces and during the build-up to the Sydney Olympic Games, he taught conflict resolution techniques to instructors from the Australian Federal Police and the Australian SAS. Still involved in the security industry on a select basis, his field experience includes a three month assignment in Iraq (2005), where he provided armed protection to volunteers from not-for-profit organisations involved in writing the new Iraqi Constitution.
