The pace bowler has taken 309 wickets in 71 five-day games with an average of 22.10.
Australia's selection chief George Bailey has confirmed that pace spearhead Cummins will have a crucial role in this winter's historic rivalry.
There were concerns that the 32-year-old might miss the series due to a ongoing back issue that remained unresolved.
Initial reports from team management suggested no definitive call had been made regarding whether he would play, with the extended contest scheduled to begin on November 21 in the WACA.
Bailey expressed that the captain is progressing and felt positive about the likelihood of participating.
"It's clear that the clock is ticking and multiple considerations around that, not only the back issue, but additional elements," he commented.
"We're encouraged. There's strong faith that he will feature a significant role. Hopefully starting in Perth. Should that not happen, we'll reassess."
Previous Setbacks
The captain missed the ODI and T20 games against India and New Zealand last month after medical tests showed a lumbar bone stress.
He has a history of recurring issues, with flare-ups in several earlier campaigns leading to absences from multiple domestic campaigns in a limited period.
Cummins stated he would be bold in recovery efforts in his comeback strategy to make the squad for the series.
Bailey noted that it was unclear if Cummins had begun bowling as part of his recovery but acknowledged it was "getting tight" for him to regain fitness for the initial match.
Contingency Plans
Should Cummins not be fit, former captain Steve Smith will assume leadership.
The talented all-rounder was recently pulled out from Australia's squad for their limited-overs matches against the Asian giants as a safety move because of soreness in his side.
The selector characterized it as a "small issue and stated that Green will play in the Sheffield Shield, so will be "ideally positioned to resume bowling."
"Considerable effort has gone into developing the strategy for him to take part for the initial game as an all-rounder," the selector detailed.
"He was only going to play the starting games anyway. How he handles the bat in limited-overs, should it hinder progress for a short period, the choice was made to take a cautious route."
