Geelong utility Oisin Mullin has penned a two-year extension, taking him to at least the end of 2027 after enjoying stellar form under Chris Scott.

Mullin was signed at the end of 2021 as a Category B Rookie following his dominance back in Ireland as a Gaelic footballer, playing in two All-Ireland finals at just the age of 21, while also earning GAA All-Star selection and Young Footballer of the Year in 2020.

He arrived at the Cats following their 2022 premiership success, and debuted shortly after in Round 9 the following season.

The 25-year-old played 18 matches in his first two years at the club, but has since doubled that number, playing all but one contest in 2025, featuring across half back and the midfield, including attempting to curb some of the competition's best players.

Geelong EGM of Football Andrew Mackie said Mullin has shown "enormous growth in a short space of time" and that his contract extension was well and truly warranted.

"Oisín has shown enormous growth in a short space of time and continues to impress us with his work ethic and willingness to learn," Mackie said.

"As with all our Irish players, we understand the enormity of the decision to move to Australia. We love having Oisín as part of our program, and we can't wait to see him play an important role for us over the next two years and beyond." 

Mullin becomes the latest to recommit to the Cats in 2025, after young defender Connor O'Sullivan signed a two-year contract extension last week, tying him to the Club until at least the end of 2028.

Geelong will look to push for a top-two spot as they enter the final four matches of the home and away campaign, starting with Port Adelaide in Round 21.
