Originally from the Dandenong Stingrays, Leppitsch made his debut in 1993 for the Bears as a 17-year old.
His breakout season was in 1999 under new coach Leigh Matthews, when he won the Brisbane Best and Fairest award, was selected as All-Australian for the first time and represented Australia in International Rules. Under Matthews, Leppitsch became a key component of the Lions spine, playing centre half back in the club’s three premiership sides from 2001 to 2003 and earned All-Australian honours in the club’s second and third flags.
Late in his career, Leppitsch battled a chronic hamstring-related back injury which inevitably ended his career. Coinciding with his retirement from the AFL at the end of 2006, Leppitsch moved in to coaching and accepted a role as an Assistant with the Lions. Leppitsch joined Richmond’s coaching ranks at the end of 2009 and was a key factor in the Tigers first Finals appearance for 12 years in 2013. Season 2014 saw Leppitsch return to where it all began, taking the reins as Senior Coach of the young and exciting Brisbane Lions. His first season in charge was highlighted by the club winning six of its final 12 games, laying the foundations for a promising future ahead. Leppitsch has returned to Richmond as an assistant coach, following three seasons as senior coach of the Brisbane Lions.
