The pace bowler has secured 309 wickets in 71 appearances with an impressive average.
Australia's selection chief the selector has confirmed that pace spearhead Cummins will have a crucial role in the upcoming Ashes series.
Rumors had circulated that the 32-year-old might be unavailable due to a ongoing back issue that was still troubling him.
Previous updates from the squad suggested no final decision had been made regarding whether he would play, with the extended contest scheduled to begin on the 21st of November in Western Australia.
Bailey expressed that the captain is progressing and felt positive about the prospects of participating.
"We know that the clock is ticking and multiple considerations involved, aside from his injury, but further aspects," the selector added.
"The outlook is good. We firmly believe that he will feature a major part. With luck from the opening match. If not, then we'll pick it up."
Past Concerns
The captain missed the ODI and T20 games against New Zealand and India in the previous weeks after medical tests showed a lower back issue.
Previous incidents include of back injuries, with setbacks in 2012-13, 2013-14 and 2015-16 forcing him out of several home seasons in four years.
The bowler mentioned he would be proactive in his approach in his comeback strategy to secure his spot for the contest.
Bailey noted that it was unclear if the captain had resumed bowling as part of his recovery but admitted it was "getting tight" for him to be fit for the initial match.
Backup Options
Should Cummins not be fit, veteran batsman Smith will lead the side.
All-rounder Cameron Green was withdrawn recently from the ODI lineup for their one-day international series against India as a precautionary measure because of discomfort in his torso.
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 be ready to bowl."
"We put so much time has gone into creating the schedule for him to take part for the initial game as an batting and bowling option," he elaborated.
"Originally, he'd only feature in the starting games anyway. The way he swings the willow in shorter formats, even if it just sets him back for 24 more hours, we just made the decision to take a cautious route."
