Connor Idun played his junior football in Geelong before representing Victoria Country in the NAB Under-18 National Championships. The GIANTS traded up in the 2018 NAB AFL Draft to secure Idun at pick 61. A developing key defender who thrives in one-on-one contests, Idun is a versatile player and - thanks to his speed - is able to play tall or small. Idun only managed three games across his first two years before being selected in round one, 2021 and going on to play 21 out of a possible 22 games, averaging 5.4 marks and 12.6 disposals per game. The 21-year-old was rewarded for his strong performance against Carlton with a NAB AFL Rising Star nomination for round 23. Idun picked up 17 touches and five marks against Carlton, and kept the retiring Eddie Betts to just two goals in the final game of his career.
