Born in Rosscarbery, County Cork, Hodnett attended Mount Saint Michael's and first began playing rugby with Clonakilty, only committing to the sport when selected for the Munster under-18s clubs team, having previously also played Gaelic games.
Hodnett was selected to represent Munster A during the 2018–19 Celtic Cup, featuring in four of the provinces fixtures. Following his performances for Munster A and Ireland under-20s, Hodnett joined the Munster academy ahead of the 2019–20 season and he made his senior competitive debut for the province in their 2019–20 Pro14 round 11 fixture against South African side Southern Kings in Irish Independent Park, Cork on 14 February 2020, with Hodnett starting at openside flanker. He scored a fantastic solo try and earned the Man-of-the-Match award in Munster's 68–3 win.

He was retained in the under-20s squad for the 2019 World Rugby Under 20 Championship when it was confirmed in May 2019 and started in the opening win against England and the defeat against Australia, before a knee injury brought an end to his participation in the tournament.
As of June 2020, Hodnett has played two games for Munster scoring one try.
