The pace bowler has claimed 309 Test scalps in 71 five-day games with an stellar bowling average.
The Australian chief selector the selector has stated that skipper Cummins will have a crucial role in this winter's England-Australia contest.
Rumors had circulated that the 32-year-old might be unavailable due to a stress fracture in his back that was still troubling him.
Earlier indications from the Australian camp suggested no final decision had been made regarding his involvement, with the five-Test series set to start on November 21 in the WACA.
He revealed that the captain is progressing and was "optimistic" about the prospects of taking part.
"We know that the window is narrowing and there are permutations involved, not just his injury, but other factors as well," the selector added.
"It's positive. There's strong faith that he'll participate in a significant role. With luck it's the first Test. Should that not happen, we'll reassess."
Past Concerns
He was sidelined Australia's limited-overs series against both Asian and Trans-Tasman rivals in the previous weeks after examinations confirmed a lumbar bone stress.
There is a track record of spinal problems, with setbacks in 2012-13, 2013-14 and 2015-16 leading to absences from several home seasons in four years.
Cummins stated he would be ""aggressive" and "take risks" in his recovery plan to make the squad for the Ashes.
He mentioned that he did not know if he had started his bowling workouts as part of his rehabilitation but conceded it was "pressing" for him to be fit for the initial match.
Backup Options
In case of absence, veteran batsman Smith will lead the side.
The talented all-rounder was recently pulled out from Australia's squad for their limited-overs matches against India as a preventive step because of an abdominal issue.
Bailey described it as a "small issue and mentioned that he'll feature in the state-level matches, so will be "well-prepared to resume bowling."
"Considerable effort has gone into building out the plan for him to take part for the opening match as an batting and bowling option," he elaborated.
"His involvement was limited to the starting games anyway. How he handles the cricket bat in white-ball cricket, if it causes any delay for a short period, we just made the decision to approach this more conservatively."
