Callum Brown was an up-and-coming Gaelic Football star playing for County Derry in Ireland before making the switch to AFL. Tall, skilful and athletic, Brown was identified by the GIANTS’ Irish scouting program in July 2017 and undertook a 12-month trial process with the club. Brown flew to Australia in August of 2018 to spend two weeks training with the GIANTS under the eye of head coach Leon Cameron. In October 2018, Brown joined the GIANTS as a Category B Rookie, the first player to join the GIANTS' men’s team directly from Ireland.
