Standing at 196cm tall, the youngster was used as swingman from the Murray Bushrangers, and was rated among the best key position prospects in the 2018 draft. He had an impressive national U18 championships for the Allies which resulted in an All-Australian selection in the position of fullback.
Koschitzke's AFL career started by playing with the Hawthorn affiliate Box Hill Hawks. Here, under the tutelage of Hawthorn aligned coaches, he spent his first year developing for the rigors of AFL football. A key position player with strong hands and a penetrating kick, he reads the game well. He is composed with the ball in hand and makes good decisions providing defensive rebound.
Koschitzke had to negotiate a difficult COVID-19 affected season. He showed promise during the pre-season games and with scratch matches against other AFL clubs. Later in the year he was moved to the forward line and seemed to thrived.
A big pre-season in 2021 and a dominant game at full forward against North Melbourne in which he kicked six goals showed that he was ready for the big time.
Koschitzke played his first AFL game for Hawthorn as part of the trio that debuted in the opening round of the 2021 AFL season against Essendon at Marvel Stadium.[4]
^The 2020 season was played with 17 home-and-away matches per team (down from 22) and 16-minute quarters with time on (down from 20-minute quarters with time on) due to the impact of the COVID-19 pandemic.
