Peter Siddle said that Australia are fine with the Stuart Broad incident and they have moved on with it.

Controversy was back to hound the first Ashes Test at Trent Bridge on Day Three in the form of umpire Aleem Dar and England all-rounder Broad, who appeared to have nicked the ball before it hit wicketkeeper Brad Haddin’s gloves and deflected into the hands of Michael Clarke at first slip. However, to the utter shock of 11 Australians on the field and a few more in the dressing room, Dar did not see it and turned down the appeal.
 
The Australians had exhausted all their Decision Review System (DRS) referrals for the innings, having wasted one on Jonny Bairstow earlier, and were understandably incensed. Broad, for all his cherubic boy-next-door looks, put on a poker face and carried on with his game. It was the second DRS-related incident in the match, after Jonathan Trott was given out to an inside edge on Day Two that Hot Spot failed to catch. You win some, you lose some, goes the saying. Both sides have now benefitted from umpiring and technological errors, but Australia would consider themselves to have gotten the rough side of the deal as Broad (47 not out) went on to share a potentially match-winning unbeaten 108-run seventh-wicket partnership with Ian Bell (95 not out) to take England to stumps on Day Three at 326 for six, with a healthy lead of 261 runs.
