Nature of WACA Ground pitch on match morning to determine whether or not Peter Handscomb will get the axe
Australia to sleep on naming Test XI
Australia will wait until the morning of day one of the third Ashes Magellan Test against England to name their XI.
Mitch Marsh is expected to be recalled at the expense of Peter Handscomb as the hosts push for an unassailable 3-0 series lead at the WACA Ground.
But captain Steve Smith and selectors are keen to have a look at the pitch on Thursday morning before making a call.
"We haven't picked the team yet," Smith told reporters. "It'll be unlucky if he (Handscomb) misses out.
"If he does miss out there's no reason he won't be back in the team soon.
"It is tough.
"If we do go down that route it's purely for the reason we think we need an extra bowler, nothing to do with anybody's batting."
Smith, who has spoken with teammates about the danger of complacency after comfortable Ashes victories in Brisbane and Adelaide, is hopeful the WACA deck will harden up overnight.
"It's probably not as hard as I would have liked it to be a day out, but 24 hours can change a wicket," he said.
"We'll have another look in the morning. Hopefully it's a bit harder and faster."
Smith has been impressed with Mitch Marsh's batting at domestic level since he underwent a shoulder reconstruction earlier this year.
"He's tightened up his defence quite a lot," Smith said.
"I know speaking to him when he was back in the team a little while ago, we spoke about softening your hands up in defence -- and those good length balls, not going so hard."
