The pace bowler has claimed 309 Test scalps in 71 Test matches with an impressive average.
Australia's selection chief Bailey has confirmed that skipper Cummins will have a crucial role in the forthcoming historic rivalry.
Rumors had circulated that the 32-year-old might be unavailable due to a persistent back stress problem that had not yet healed.
Earlier indications from team management suggested no definitive call had been made regarding his involvement, with the extended contest set to start on the 21st of November in the WACA.
He revealed that his recovery is on track and remained hopeful about the prospects of being involved.
"It's clear that time is getting short and there are permutations at play, not just his injury, but additional elements," Bailey remarked.
"We're encouraged. There's strong faith that he will feature a significant role. With luck starting in Perth. If not, we'll reassess."
Injury History
He was sidelined Australia's limited-overs series against New Zealand and India in the previous weeks after examinations confirmed a lumbar bone stress.
There is a track record 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 ""aggressive" and "take risks" in his recovery plan to make the squad for the series.
Bailey noted that there was no confirmation if Cummins had begun bowling as part of his rehabilitation but admitted it was "becoming urgent" for him to regain fitness for the initial match.
Contingency Plans
In case of absence, ex-skipper Smith will take over the captaincy.
The talented all-rounder was excluded lately from the national team for their one-day international series against the subcontinent side as a safety move because of an abdominal issue.
He labeled it as a "small issue and stated that Green will play in the Sheffield Shield, so will be "well-prepared to be ready to bowl."
"We put so much time has gone into creating the schedule for him to participate for the initial game as an dual-role player," the selector detailed.
"He was only going to play the first two ODIs in any case. His aggressive style the bat in limited-overs, should it hinder progress for another day, we just made the decision to adopt a safer strategy."
