Geelong (2025) After being overlooked by all 18 clubs in the
national draft earlier that same week, Retschko was drafted by with the club's second pick and the 23rd selection overall in the
2025 rookie draft. He failed to make a debut at AFL level in 2025, instead spending the entirety of the season with the club's reserves side in the
VFL. He finished the season having played 18 matches for that side, placing fourth on the goal kicking tally (13), second on the total disposals tally (379) and averaging 21.6 disposals and four marks per game. Retschko placed fifth in the VFL team best and fairest award, ranking second among players also listed with the AFL side. Geelong announced the club would de-list him at the end of the 2025 season.
Richmond (2026–present) Despite having already agreed to join as a delisted free agent in the forthcoming November signing period, the club opted to acquire him via a trade for draft pick number 99 in the exchange period in October 2025, before his de-listing by Geelong had officially been lodged. Retschko made his first appearances for the club in two pre-season matches in February 2026, before missing selection for the team's round 1 AFL side. He featured in three VFL matches in March and April, recording an average of 23.7 disposals per game before being selected to make his AFL debut in round 6 of the 2026 season, in a match against at
Marvel Stadium. ==Player profile==
