Two former England captains have had their say - describing Bairstow as living "in his own bubble" and "dozy":
Former England white-ball captain Eoin Morgan:
"There was a huge sense of frustration [in the crowd] but I can't understand why? It's complete naivety around Bairstow's dismissal.
"The ball is not dead at any stage when Bairstow leaves his crease. He was obviously in his own little bubble - and you cannot do that.
"It's actually really smart from Carey, recognising what is going on - Bairstow living in his own little world - and seeing an opportunity to take a wicket. I don't see it compromising the spirit of the game."
Former England captain, Sir Andrew Strauss:
"Australia are the villains, as far as England fans are concerned - especially Cummins and his decision not to withdraw that appeal of Bairstow.
"Cummins will get plenty of stick for the rest of the series, I would've thought, off the back of that.
"You could argue that it was against the spirit of cricket. In truth, I think there was absolutely nothing wrong with it but, of course, the crowd will see it through English patriotic eyes.
"Bairstow was being dozy going outside of his crease. I was pretty comfortable with what Australia did."
