Lohmann made his debut in Round 5 of the 2022 AFL season against Collingwood[2] Although he only managed 8 games in 2 seasons with the Lions, Lohmann still signed a two-year contract extension with the team in September 2023,[3] despite Essendon showing interest in signing him.[4] The contract extension proved to ignite his career, playing every game of the 2024 season as of round 10.[5] Lohmann kicked 5 goals from 14 disposals against Richmond in a 119-point victory at the Gabba in round 10. The performance earned him a rising star nomination.[6]
Lohmann was part of the Brisbane Lions 2024 premiership winning team, kicking 4 goals in the Grand Final.[7] He was one of four players to receive votes for the Norm Smith Medal. Lohmann kicked a total of nine goals in Brisbane's drought-breaking finals series. Along with ten teammates, Lohmann became just the second player to play 27 games in a single AFL season.[8]
