Clarke was recruited to for the 1933 season, having been considered one of the best juniors in Western Australia the previous season. Clarke had an outstanding season, winning the
Sandover Medal for the
fairest and best player in the competition, despite his club winning the
wooden spoon that season. He again won the medal in 1934, becoming the first back-to-back winner of the award. He missed the 1938 premiership win while undergoing training in England with the
Royal Air Force (RAF), having worked his way overseas and back on a freighter. During the
1939 season, Clarke played in Claremont's premiership-winning team and also played his 100th game for the club. In the off-season, he purchased a
mercery business in
Busselton, and thus did not play in the WANFL in 1940. He returned to Perth prior to the beginning of the 1941 season, with Claremont enlisting his services for one final season. Clarke finished his WANFL career with 133 games and six goals. He also represented
Western Australia in eight interstate matches, captaining the side against South Australia at
Leederville Oval in 1934 and playing in the
1937 Australian National Football Carnival, which Perth hosted. ==Military career and death==
