A member of Fremantle's Next Generation Academy, Western represented Western Australia at the U16 Championships in 2018, and since then, has had two impressive seasons for Claremont at WAFL colts level. No player at colts level over the past two years has had more contested possessions, ground ball gets and inside 50s than Western and he has also had the second most disposals, score involvements and running bounces in those seasons. His regular good form was recognised when he won Claremont's Most Consistent Award in 2020. Western was also a major contributor in Claremont's premiership-winning season in 2019; he recorded 23 disposals, 15 contested possessions, four clearances and six tackles in the grand final. Having played primarily as a midfielder over the last two years, Western is equally effective as a small forward where he can utilise his lightning speed, clean hands, defensive pressure and goal sense. The 18-year-old didn't test at the 2020 WA Combine, but his 2.73 seconds 20m time in February 2019 would be quicker than the all-time national combine record, set in 2010.
