The pace bowler has secured 309 Test scalps in 71 Test matches with an stellar bowling average.
The Australian chief selector the selector has confirmed that skipper Cummins will have a crucial role in the forthcoming historic rivalry.
Speculation had been growing that the 32-year-old might sit out due to a stress fracture in his back that was still troubling him.
Earlier indications from the Australian camp suggested no definitive call had been made regarding Cummins' participation, with the Test matches kicking off on November 21 in Western Australia.
The selector shared that his recovery is on track and remained hopeful about the prospects of taking part.
"It's clear that the window is narrowing and multiple considerations at play, aside from his injury, but additional elements," he commented.
"The outlook is good. [We are] really confident that he will feature a significant role. Ideally starting in Perth. Should that not happen, then we'll pick it up."
Past Concerns
The captain missed the white-ball matches against India and New Zealand recently after examinations confirmed a lower back issue.
Previous incidents include of spinal problems, with flare-ups in 2012-13, 2013-14 and 2015-16 leading to absences from multiple domestic campaigns in a limited period.
The bowler mentioned he would be bold in recovery efforts in his recovery plan to secure his spot for the contest.
The selector indicated that it was unclear if the captain had resumed bowling as part of his recovery but admitted it was "becoming urgent" for him to be fit for the opener.
Alternative Arrangements
Should Cummins not be fit, veteran batsman Smith will take over the captaincy.
The talented all-rounder was excluded lately from Australia's squad for their limited-overs matches against India as a precautionary measure because of soreness in his side.
The selector characterized it as a "small issue and confirmed that he'll feature in the state-level matches, so will be "in a good place to deliver overs."
"Considerable effort has gone into building out the plan for him to take part for the first Test as an dual-role player," the selector detailed.
"He was only going to play the first two ODIs anyway. The way he swings the cricket bat in white-ball cricket, should it hinder progress for 24 more hours, we just made the decision to adopt a safer strategy."
