The pace bowler has secured over 300 dismissals in 71 appearances with an stellar bowling average.
The Australian chief selector the selector has declared that captain Pat Cummins will have a crucial role in the upcoming historic rivalry.
Speculation had been growing that the 32-year-old might sit out due to a persistent back stress problem that was still troubling him.
Initial reports from team management suggested no final decision had been made regarding his involvement, with the Test matches set to start on 21 November in Perth.
He revealed that the captain is progressing and remained hopeful about the likelihood of being involved.
"It's clear that time is getting short and there are permutations at play, not just the back issue, but other factors as well," Bailey remarked.
"It's positive. [We are] really confident that he's going to play a major part. With luck starting in Perth. Otherwise, we'll reassess."
Injury History
Cummins was ruled out the ODI and T20 games against India and New Zealand last month after scans revealed a stress reaction in his back.
Previous incidents include of recurring issues, with flare-ups in 2012-13, 2013-14 and 2015-16 leading to absences from multiple domestic campaigns in four years.
He emphasized he would be proactive in his approach in his recovery plan to make the squad for the series.
He mentioned that there was no confirmation if Cummins had begun bowling as part of his rehabilitation but conceded it was "getting tight" for him to be fit for the first Test.
Contingency Plans
Should Cummins not be fit, ex-skipper Smith will assume leadership.
Versatile player Green was recently pulled out from the national team for their ODI contests against the subcontinent side as a safety move because of discomfort in his torso.
Bailey described it as a "small issue and mentioned that Green will play in the Sheffield Shield, so will be "well-prepared to resume bowling."
"Considerable effort has gone into building out the plan for him to be available for the opening match as an batting and bowling option," Bailey explained.
"He was only going to play the first two ODIs anyway. How he handles the bat in limited-overs, if it causes any delay for a short period, the choice was made to take a cautious route."
