All-Ireland Senior Football Championship following some impressive NFL performances in the full-forward line. Walsh made his championship debut came against Clare in the
Munster Senior Football Championship, scoring a point. He regained his place and a number of impressive performances saw him named as
All Stars Young Footballer of the Year. Players' agent Ricky Nixon described it as a 'big coup' for the AFL and said '"I can't tell you if he'll want to play or stay or if he'll be good enough but he's definitely one of the best talents that I've seen."

2009 National Football League In 2009, Walsh suffered injury in the early part of the championship, which saw
Cork knock Kerry out of the
2009 Munster SFC. Kerry came through the qualifiers to meet
Dublin in the
2009 All-Ireland SFC quarter-final, but Walsh was not on top form and was replaced before half-time. He was dropped from the team but came on as a substitute during the second half of the semi-final, and a more impressive performance saw him regain his place for the final. In the
2009 All-Ireland SFC final, in which Kerry overcame Cork, Walsh notched up four points from play (two with each foot). ==Australian rules football==
