The pace bowler has secured over 300 dismissals in 71 appearances with an stellar bowling average.
The Australian chief selector the selector has stated that pace spearhead Cummins will be a central figure in the upcoming historic rivalry.
There were concerns that Cummins might sit out due to a persistent back stress problem that had not yet healed.
Earlier indications from the Australian camp suggested no final decision had been made regarding his involvement, with the five-Test series scheduled to begin on 21 November in Western Australia.
Bailey expressed that the captain is progressing and was "optimistic" about the likelihood of being involved.
"We're aware that the clock is ticking and multiple considerations at play, aside from the back issue, but other factors as well," the selector added.
"It's positive. There's strong faith that he's going to play a key capacity. Ideally starting in Perth. If not, then we'll pick it up."
Injury History
The captain missed the ODI and T20 games against New Zealand and India last month after medical tests showed a lumbar bone stress.
Previous incidents include of back injuries, with flare-ups in 2012-13, 2013-14 and 2015-16 leading to absences from several home seasons in four years.
Cummins stated he would be proactive in his approach in his rehabilitation process to ensure his availability for the contest.
Bailey noted that there was no confirmation if the captain had resumed bowling as part of his comeback but conceded it was "becoming urgent" for him to be fit for the initial match.
Contingency Plans
In case of absence, ex-skipper Smith will assume leadership.
The talented all-rounder was recently pulled out from the national team for their one-day international series against India as a precautionary measure because of soreness in his side.
He labeled it as a "minor" injury and confirmed that he's scheduled to appear in the domestic first-class competition, so will be "in a good place to resume bowling."
"Considerable effort has gone into creating the schedule for him to be available for the opening match as an dual-role player," he elaborated.
"Originally, he'd only feature in the first two ODIs regardless. His aggressive style the cricket bat in white-ball cricket, should it hinder progress for another day, the choice was made to take a cautious route."
