Australia on Thursday kept New Zealand guessing as they consider playing two spinners for the third and final Test at Sydney.
The home side, who comfortably won the opening two Test matches, have called up leg-spinner Mitchell Swepson, who might bowl in combination with Nathan Lyon depending on the inspection of the pitch before toss.
"We're just weighing up whether we play the second spinner and if we did, how we would do that," skipper Tim Paine told reporters ahead of the game.
"As JL (coach Justin Langer) touched on yesterday, I think at the moment it would be likely that we would go unchanged but there's still a possibility, if we see that wicket tomorrow morning, that we could play another spinner."
If Australia go ahead with a second spinner, Matthew Wade is likely to face the axe as Travis Head scored his second Test hundred at the MCG.
An unchanged team would mean Lyon, alongside the trio of quicks will be retained as they decimated the opposition with a convincing 247-run win over New Zealand.
Paine said the team was flexible enough to manage things if they whether they dropped a batter or a quick bowler.
"Luckily we could probably do both if we had to," he said.
"We've got some guys around our squad that could provide quite a bit of flexibility and even with someone like James Pattinson can really lengthen our batting anyway."
Australia have won all four Tests this home summer – two each against Pakistan and New Zealand, after retaining the Ashes in English summer.
Paine has termed this ‘teamwork’, with players stepping up in case anyone is having a bad day at the office.
