Bio

Kasey Bos is an exciting Australian left-back who has emerged through the A-League Men and earned a move to European football.

The younger brother of CommBank Socceroo Jordy Bos, Kasey enjoyed a breakthrough campaign with Melbourne Victory in 2024/25, contributing four goals and two assists as the club reached the A-League Men Grand Final. His performances earned him a first senior national team call-up in June 2025.

Bos subsequently secured a move to Bundesliga club Mainz 05 before joining Dutch side Excelsior Rotterdam on loan. An energetic and attack-minded full-back, his progression in Europe has seen him remain part of the senior Socceroos set-up as he pushes for his international debut.
