[3] Curtin's brother Cody plays for Claremont and will nominate for the upcoming 2025 national draft.
Curtin seemed a perfect suitor for Adelaide, who were lacking defensive height due to the departure of Tom Doedee and the injuries of Nick Murray and Jordon Butts.
[6][7] His long-awaited debut was announced on 30 April, 2024, two days prior to the round 8 Showdown versus Port Adelaide.
He was substituted off tactically at three quarter time and replaced by veteran Brodie Smith.
It wasn't until round 22 against the Western Bulldogs that Curtin played an entire game without being substituted, and he made it count by kicking his first two career goals as well as creating three clearances.
