The pace bowler has claimed 309 Test scalps in 71 Test matches with an average of 22.10.
Australia's chair of selectors George Bailey has declared that pace spearhead Cummins will play a "major part" in this winter's historic rivalry.
Rumors had circulated that the 32-year-old might sit out due to a persistent back stress problem that remained unresolved.
Initial reports from the squad suggested no final decision had been made regarding whether he would play, with the Test matches kicking off on the 21st of November in Perth.
The selector shared that the captain is progressing and was "optimistic" about the likelihood of being involved.
"It's clear that time is getting short and various factors around that, not just his injury, but additional elements," the selector added.
"The outlook is good. We firmly believe that he'll participate in a major part. With luck starting in Perth. Otherwise, we'll reassess."
Previous Setbacks
Cummins was ruled out the white-ball matches against New Zealand and India recently after medical tests showed a lower back issue.
Previous incidents include of spinal problems, with recurrences in several earlier campaigns forcing him out of three Australian summers in a short span.
Cummins stated he would be bold in recovery efforts in his recovery plan to ensure his availability for the Ashes.
The selector indicated that it was unclear if Cummins had begun bowling as part of his comeback but acknowledged it was "getting tight" for him to regain fitness for the first Test.
Alternative Arrangements
Should Cummins not be fit, ex-skipper Smith will take over the captaincy.
The talented all-rounder was recently pulled out from the ODI lineup for their limited-overs matches against India as a precautionary measure because of soreness in his side.
He labeled it as a "slight concern and mentioned that he'll feature in the domestic first-class competition, so will be "ideally positioned to resume bowling."
"We put so much time has gone into developing the strategy for him to be available for the opening match as an all-rounder," the selector detailed.
"His involvement was limited to the first two ODIs anyway. His aggressive style the cricket bat in white-ball cricket, if it causes any delay for 24 more hours, the choice was made to approach this more conservatively."
