The Australian skipper has taken 309 Test scalps in 71 appearances with an average of 22.10.
The Australian selection chief 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 ongoing back issue that was still troubling him.
Initial reports from the squad suggested no official announcement had been made regarding Cummins' participation, with the extended contest kicking off on the 21st of November in Perth.
He revealed that Cummins is "building up" and was "optimistic" about his chances of being involved.
"We're aware that the clock is ticking and various factors at play, aside from the physical problem, but other factors as well," the selector added.
"We're encouraged. There's strong faith that he will feature a significant role. Hopefully starting in Perth. If not, we'll adjust."
Previous Setbacks
The captain missed the ODI and T20 games against India and New Zealand last month after scans revealed a stress reaction in his back.
There is a track record of recurring issues, with flare-ups in several earlier campaigns leading to absences from multiple domestic campaigns in four years.
The bowler mentioned he would be ""aggressive" and "take risks" in his recovery plan to secure his spot for the Ashes.
Bailey noted that there was no confirmation if Cummins had begun bowling as part of his rehabilitation but conceded it was "becoming urgent" for him to be fit for the opener.
Backup Options
Should Cummins not be fit, ex-skipper Smith will assume leadership.
The talented all-rounder was recently pulled out from Australia's squad for their limited-overs matches against India as a precautionary measure because of an abdominal issue.
He labeled it as a "minor" injury and mentioned that he'll feature in the domestic first-class competition, so will be "well-prepared to resume bowling."
"We put so much time has gone into building out the plan for him to participate for the opening match as an dual-role player," he elaborated.
"Originally, he'd only feature in the starting games in any case. His aggressive style the bat in limited-overs, even if it just sets him back for a short period, we just made the decision to adopt a safer strategy."
