Played U19s from 1977 to 1979.
Named in best players on multiple occasions and kicked several goals, including the only two goals for the whole team in the Round 19 U19s game against North Melbourne, strangely Harry was not named in the best players for that game.
Harry Van Koll would later player with St Kilda reserves in 1983 and was listed as No.44 on their playing list.
Brother of fellow U19s player Riny Van Koll.
