AFL Women's career
Tonon made her AFL Women's debut in round four of 2022 (S6). She began her professional career playing as a forward, playing a further two games for the year.
While struggling for selection, Tonon managed appearances in the following two seasons, but it wasn't until 2024 that she broke into the team permanently. The utility became a consistent performer for the Crows, featuring in all but two of the club's matches.[4] She also kicked her first goal for the club in round one against Port Adelaide.[5] Prior to the 2025 season, Tonon extended her contract until the end of 2026.[6]
