The pace bowler has secured over 300 dismissals in 71 five-day games with an stellar bowling average.
Australia's chair of selectors the selector has confirmed that skipper Cummins will play a "major part" in the upcoming historic rivalry.
There were concerns that the 32-year-old might miss the series due to a ongoing back issue that was still troubling him.
Initial reports from the squad suggested no definitive call had been made regarding whether he would play, with the extended contest set to start on November 21 in Perth.
The selector shared that the captain is progressing and remained hopeful about the likelihood of taking part.
"It's clear that the clock is ticking and multiple considerations at play, not just the physical problem, but additional elements," the selector added.
"It's positive. There's strong faith that he'll participate in 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 scans revealed a lumbar bone stress.
There is a track record of spinal problems, with recurrences in multiple past seasons causing him to miss several home seasons in four years.
Cummins stated he would be ""aggressive" and "take risks" in his comeback strategy to secure his spot for the Ashes.
The selector indicated that it was unclear if the captain had resumed bowling as part of his rehabilitation but admitted it was "pressing" for him to recover fully for the initial match.
Alternative Arrangements
In case of absence, ex-skipper Smith will assume leadership.
The talented all-rounder was withdrawn recently from Australia's squad for their ODI contests against the Asian giants as a safety move because of an abdominal issue.
He labeled it as a "small issue and confirmed that he'll feature in the state-level matches, so will be "in a good place to resume bowling."
"Extensive planning has gone into building out the plan for him to participate for the opening match as an batting and bowling option," the selector detailed.
"Originally, he'd only feature in the starting games regardless. The way he swings the cricket bat in white-ball cricket, even if it just sets him back for a short period, we opted to take a cautious route."
