David Warner has clapped back at Tim Southee after the New Zealand bowler struck Australian opener Joe Burns with a throw at the stumps.
Bowling his third over on day one at Perth Stadium, Southee fielded a block from Burns and immediately threw the ball back at the batsman.
After what former Australian captain Ricky Ponting described as "a little rush of blood", Southee's actions were admonished by Warner.
The Kiwi told his rival that Burns was "in front of the wicket", suggesting it was Burns's fault for getting in the way of the attempted run out, but Warner disagreed.
"Hey, come on," he said.
"You're supposed to be Mr Nice Guys."
New Zealand great Brendon McCullum jokingly assessed that Southee "got that one horribly wrong" after the ball stuck in his hands.
Ponting described the clash as what's expected out of a Test match between the two nations.
But the Channel 7 commentator hinted Southee could get as much as he gives later.
"I tell you what the Aussies will notice there though," Ponting said.
"There was no apology there. He didn't say sorry at all."
Burns later fell for nine runs when he was trapped lbw by Colin de Grandhomme in a successful bowling change by New Zealand captain Kane Williamson.
The Australian opener opted against a review but replays showed the ball was missing the stumps.
