Justin grew up in Viewbank, Victoria with his older brother and sister. He attended Marcellin College in Bulleen and developed a love of footy from an early age.

Known as a lightning-quick endurance machine and a clean user of the footy who’s best used on a wing or at half-back, Justin’s work ethic always impressed his coaches throughout his junior years and continued into his draft year. He made a name for himself in the TAC Cup as one of the hardest workers in the draft whom can break a game open. He went on to represent Vic Metro in the Under 18 Championships where he displayed traits of an AFL footballer in his four matches. As a result, Justin was drafted by the Swans in the 2018 National Draft and was fortunate to debuted in Round 4 of the 2019 season.
