David Warner will ramp up his bid to bolster the struggling Australian batting line-up when the squad reconvenes for training on Saturday ahead of the third Test against India.
The pugnacious opener is back in the extended squad after missing the first two matches of the Border-Gavaskar series with a groin injury picked up during the ODI series.
In his absence, Australia failed to score more than 200 in any of their three completed innings in Adelaide and Melbourne.
Only makeshift opener Matthew Wade (27.75), Marnus Labuschagne (32.25) and captain Tim Paine (43.50) are averaging more than 23 for the series.
Joe Burns was axed from the squad after an unacceptable return in the Boxing Day Test and seven single-figure scores in eight innings, including three ducks, against touring Indian teams this summer.
Warner, Marcus Harris and possible debutant Will Pucovski, who still needs to be given final clearance after his latest bout of concussion, are all possible inclusions at the top of the order in Sydney.
The Australian players have been given three days off after the eight-wicket defeat in the Boxing Day Test and will train in Melbourne on Saturday before travelling to Sydney on Monday.
If he is cleared to play, prolific left-hander Warner will be a huge boost to Australia for the crucial third Test, with the series tied at 1-1.
"He's a big inclusion for us if he does come back in," Labuschagne said.
"He's someone with over 7000 Test runs and averaging near-on 50, he's a superb player.
"He's in that top calibre of player and his energy around the group and in the field will be terrific.
"It will be great to have him."
Sydney's hosting of the third Test had been in grave doubt because of the city's COVID-19 outbreak, but the schedule has been given the green light by government and health authorities.
Labuschagne has fond recent memories of the SCG, having made his highest Test score there with a magnificent 215 against New Zealand a year ago.
"It's a beautiful venue to bat at and it has been, at times, quite batting-friendly," Labuschagne said.
"But with two world-class bowling attacks it's always hard work, it doesn't matter what the wicket's like."
