The pace bowler has taken over 300 dismissals in 71 Test matches with an impressive average.
Australia's chief selector George Bailey has stated that pace spearhead Cummins will have a crucial role in the forthcoming historic rivalry.
Speculation had been growing that the 32-year-old might miss the series due to a persistent back stress problem that remained unresolved.
Earlier indications from the Australian camp suggested no definitive call had been made regarding whether he would play, with the Test matches kicking off on November 21 in the WACA.
The selector shared that the captain is progressing and was "optimistic" about the prospects of taking part.
"We know that the window is narrowing and various factors around that, aside from the physical problem, but further aspects," the selector added.
"We're encouraged. There's strong faith that he's going to play a key capacity. Hopefully from the opening match. Should that not happen, then we'll pick it up."
Injury History
Cummins was ruled out the ODI and T20 games against India and New Zealand last month after examinations confirmed a stress reaction in his back.
There is a track record of back injuries, with flare-ups in several earlier campaigns causing him to miss several home seasons in a short span.
Cummins stated he would be bold in recovery efforts in his rehabilitation process to make the squad for the series.
Bailey noted that it was unclear if Cummins had begun bowling as part of his comeback but admitted it was "pressing" for him to regain fitness for the first Test.
Backup Options
In case of absence, former captain Steve Smith will take over the captaincy.
Versatile player Green was excluded lately from Australia's squad for their limited-overs matches against India as a safety move because of an abdominal issue.
Bailey described it as a "minor" injury and stated that he'll feature in the domestic first-class competition, so will be "well-prepared to deliver overs."
"We put so much time has gone into building out the plan for him to participate for the opening match as an dual-role player," the selector detailed.
"His involvement was limited to the first two ODIs anyway. How he handles the cricket bat in white-ball cricket, should it hinder progress for another day, we opted to approach this more conservatively."
