The pace bowler has taken over 300 dismissals in 71 appearances with an average of 22.10.
The Australian chief selector the selector has declared that skipper Cummins will play a "major part" in the forthcoming 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 team management suggested no definitive call had been made regarding whether he would play, with the extended contest set to start on the 21st of November in Perth.
He revealed that his recovery is on track and was "optimistic" about the likelihood of taking part.
"We're aware that the clock is ticking and multiple considerations around that, aside from his injury, but other factors as well," the selector added.
"The outlook is good. We firmly believe that he'll participate in a major part. Hopefully from the opening match. Should that not happen, then we'll pick it up."
Past Concerns
He was sidelined Australia's limited-overs series against India and New Zealand recently after scans revealed a stress reaction in his back.
He has a history of spinal problems, with setbacks in several earlier campaigns leading to absences from several home seasons in four years.
Cummins stated he would be proactive in his approach in his comeback strategy to make the squad for the Ashes.
Bailey noted that there was no confirmation if Cummins had begun bowling as part of his rehabilitation but conceded it was "getting tight" for him to regain fitness for the initial match.
Contingency Plans
In case of absence, veteran batsman Smith will assume leadership.
Versatile player Green was excluded lately from the national team for their one-day international series against India as a preventive step because of soreness in his side.
The selector characterized it as a "small issue and stated that he's scheduled to appear in the state-level matches, so will be "ideally positioned to be ready to bowl."
"Considerable effort has gone into developing the strategy for him to be available for the initial game as an batting and bowling option," Bailey explained.
"Originally, he'd only feature in the first two ODIs in any case. His aggressive style the willow in shorter formats, if it causes any delay for a short period, the choice was made to take a cautious route."
