Michael Clarke believes none of his players overstepped the mark in their treatment of dismissed New Zealand batsmen in Sunday's World Cup victory at the MCG.

Martin Guptill, Grant Elliott and Dan Vettori each received hefty send-offs, with Australia wicketkeeper Brad Haddin involved in confrontations with Guptill and Elliott.

Black Caps captain Brendon McCullum declined to delve into the issue when pressed on it after the match.

"It wasn't really discussed within the group. Send-offs are send-offs. It's not something we necessarily are concerned about," he said.

"I think the focus should be on how well Australia played and how they deserve this victory, rather than any minor issues on the way through."

Australia captain Clarke said he had not witnessed any behaviour he had been unhappy about.

"I can't remember a player getting a send-off. Maybe I was too far from the action," he said.

"Obviously it's a World Cup final. There's passion, there's excitement, there's adrenalin running through the guys' bodies."

Clarke said if anything did occur, it may have been retaliatory.

"You cop as good as you give. I know this team has copped a fair bit of stick throughout this World Cup," he said.

"The boys have got long memories. Maybe there was something there [from the Auckland match]; I'm not too sure.

"I don't think there was anything that was below the belt."
