Former Kerry star Tommy Walsh is finally set to make his Australian Rules debut for St Kilda in the pre-season NAB Cup.

The former Young Footballer of the Year moved to the Melbourne club following Kerry’s All-Ireland win in 2009, and spent last season learning the ropes at Sandringham, St Kilda’s junior club, in the Victorian Football League.

St Kilda coach Ross Lyon said on the club's website that he was hoping to use Walsh in several roles during the upcoming NAB Cup matches with Essendon and Brisbane, and that the Tralee man has exceeded expectations since moving to the club.

'He will play at full-back, in the ruck (midfield) and forward. He is a key position player. He might not like hearing he's going into the ruck but it's an opportunity for him,' Lyon said.

'He came fourth or fifth in the Sandringham best and fairest last season. It's a pretty high standard and to deliver on that has exceeded everyone's expectation.'
