Dariean served four years as a rifleman in the Australian Army, specialising in Direct Fire Support Weapons (DFSW). After leaving the army, he relocated to Bendigo and devoted himself to training in mixed martial arts.
With high discipline and motivation, Dariean competed in his first amateur mixed martial arts fight within a year of training and secured a victory. Since that win, he has focused on honing his striking skills, with a particular emphasis on boxing, kickboxing and Muay Thai.
