Picked up Swan Districts in 1934, Krepp played for most of the season.[5] Krepp had an impressive season and the 168 centimetres (5.5 ft) and 64 kilograms (141.1 lb) winger was pressing for state selection. He was noted for his sharp turns and evasive maneuvers and precise kicking skills with both feet.[6]
A speedy and rugged wingman,[7] Krepp was one of Swan Districts' best players and won the club's fairest and best award three times.
As part of his excellent 1935 season Krepp also played for the state team which was defeated by the Victorian side by 13 points. Krepp shone on the wing and was one of the few centre-line players who outplayed his opponent.[8] He was selected again to play for the state against South Australia later the same year.[9]
He was the first Swan Districts player to win a Sandover Medal when he tied with Lou Daily from Subiaco in 1935.[2][10]
In 1936 Krepp was gain selected to play for his state against the South Australians. Western Australia lost the game by a single point with Krepp playing a good game until he was injured late in the game and was replaced by "Bluey" Matthews.[12]
Krepp married Gladys Reid in 1939 in the Ross Memorial Church.[13]
