Growing up in
Narrandera in southern NSW, Flynn joined the
Giants Academy at the age of 12. He was selected with pick 41 in the
2015 AFL draft as a developing
ruckman. Flynn didn't make his AFL debut in his first five years at the club, missing an entire year after an
ACL injury in July 2019. He then played 33 games from his debut in 2019, before he spent the end of the 2023 season playing in the VFL as the Giant's preferred
Kieren Briggs as their first choice ruckman. At the end of the
2023 AFL season, Flynn joined as a
free agent. A hamstring injury during preseason delayed his debut for the Eagles until round 12 of the
2024 AFL season. Flynn was also appointed as the ruck coach of the
West Coast Eagles AFL Women's (AFLW) team ahead of the 2024 season. ==Statistics==
