Australian captain Aaron Finch is set to resist any call for mass change to his team after Saturday night's flogging at the hands of New Zealand in Sydney to open the Super 12 round of the T20 World Cup.

Australia found themselves on the back foot from the get-go in a game which has put a major dent in their chances of winning through to the semi-finals at the tournament.

Australia will now likely need to win four from four in their remaining matches to have a chance at moving through to the tournaments, and even then the size of Saturday's loss means their net run rate could still be a question.

Further to that, rain continues to hang around Australia and could lead to a no result against one of the other sides - being England, Sri Lanka, Afghanistan and Ireland in their group.

Despite the loss to New Zealand, where Australia were first blown out by Finn Allen during the powerplay, then refused to use more than five bowlers despite having Glenn Maxwell and Mitchell Marsh not bowl an over, before regular wickets saw an 89-run loss, Finch told reporters that he isn't interested in making big changes, with only one up for consideration.

"We still feel as though we have the right structure of team and we've got the right players to win the World Cup," Finch told reporters.

"Whether you go in with an extra spinner or an extra quick, that's the only real decision to be made."

That could pave the way for Ashton Agar to come into the squad, however, the vast majority of questions will hinge on Steve Smith, who could have made a difference against the Black Caps with his ability to rotate strike.

Finch seemed to suggest there would be no changes to the batting line up though.

"You can't go into your shell in T20 cricket. You have to be able to transfer pressure back onto the opposition as quick as you can," he said.

"At times, that comes with risk. You have to prepared to wear the consequences of taking risks.

"We haven't gotten it totally right with bat or ball, we've got to look at ourselves in that regard, but I'm still committed to playing the same way that won us the last World Cup."

Australia will play Sri Lanka on Tuesday night in Perth.
