Gidley became famous for his wing/centre combination with former Knight Timana Tahu. A common play was for the ball to be sent out to the right side of the field where Gidley would run, draw one or two players in before doing the famous Gidley flick pass to Tahu or placing a grubber kick down the line. This play was used at both club and representative level.
2006 saw a rejuvenation of sorts for Gidley seeing him recapture some of his old magic flick pass play with Knights winger Brian Carney. In 2006 Gidley retired from representative football, aiming to focus on playing well at club level. This move was questionable as it was right before the annual City vs Country Origin clash, where many thought Gidley was going to make the Country side in the centre position.
He became only the 4th Newcastle Knight to play more than 200 career games.
In 2011 Gidley returned to the Newcastle Knights as the Business Development Manager before being appointed the CEO of Football Operations in June 2011 by the new owners, Hunter Sports Group. Meanwhile his younger brother Kurt was club captain.
