The pace bowler has taken 309 Test scalps in 71 five-day games with an average of 22.10.
The Australian chief selector George Bailey has declared that skipper Cummins will be a central figure in the forthcoming historic rivalry.
Speculation had been growing that the 32-year-old might miss the series due to a ongoing back issue that was still troubling him.
Initial reports from the Australian camp 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.
The selector shared that the captain is progressing and was "optimistic" about his chances of being involved.
"We know that the clock is ticking and various factors around that, not just the physical problem, but additional elements," the selector added.
"We're encouraged. There's strong faith that he'll participate in a major part. Ideally starting in Perth. If not, we'll reassess."
Previous Setbacks
Cummins was ruled out the white-ball matches against India and New Zealand in the previous weeks after medical tests showed a lower back issue.
Previous incidents include of spinal problems, with recurrences in several earlier campaigns forcing him out of several home seasons in four years.
He emphasized he would be bold in recovery efforts in his rehabilitation process to secure his spot for the series.
The selector indicated that he did not know if he had started his bowling workouts as part of his rehabilitation but conceded it was "becoming urgent" for him to be fit for the first Test.
Backup Options
If he's unavailable, former captain Steve Smith will take over the captaincy.
The talented all-rounder was excluded lately from the national team for their ODI contests against the Asian giants as a preventive step because of discomfort in his torso.
Bailey described it as a "small issue and mentioned that he'll feature in the state-level matches, so will be "in a good place to be ready to bowl."
"Extensive planning has gone into developing the strategy for him to be available for the first Test as an batting and bowling option," the selector detailed.
"Originally, he'd only feature in the first two ODIs in any case. The way he swings the bat in limited-overs, if it causes any delay for 24 more hours, the choice was made to adopt a safer strategy."
