The pace bowler has claimed 309 Test scalps in 71 five-day games with an stellar bowling average.
Australia's chief selector the selector has declared that skipper Cummins will play a "major part" in this winter's Ashes series.
Rumors had circulated that the 32-year-old might be unavailable due to a persistent back stress problem that remained unresolved.
Earlier indications from the squad suggested no official announcement had been made regarding his involvement, with the five-Test series kicking off on November 21 in Western Australia.
The selector shared that Cummins is "building up" and felt positive about his chances of being involved.
"We know that the window is narrowing and there are permutations involved, aside from the back issue, but other factors as well," he commented.
"We're encouraged. There's strong faith that he will feature a significant role. With luck from the opening match. If not, we'll adjust."
Past Concerns
He was sidelined the white-ball matches against India and New Zealand recently after medical tests showed a lower back issue.
There is a track record of recurring issues, with setbacks in multiple past seasons forcing him out of three Australian summers in four years.
He emphasized he would be ""aggressive" and "take risks" in his comeback strategy to make the squad for the contest.
Bailey noted that it was unclear if the captain had resumed bowling as part of his recovery but acknowledged it was "pressing" for him to regain fitness for the opener.
Backup Options
Should Cummins not be fit, veteran batsman Smith will take over the captaincy.
Versatile player Green was excluded lately from the national team for their limited-overs matches against India as a precautionary measure because of discomfort in his torso.
The selector characterized it as a "slight concern and stated that he's scheduled to appear in the domestic first-class competition, so will be "ideally positioned to deliver overs."
"We put so much time has gone into building out the plan for him to be available for the initial game as an batting and bowling option," Bailey explained.
"Originally, he'd only feature in the starting games regardless. The way he swings the cricket bat in white-ball cricket, even if it just sets him back for a short period, we opted to take a cautious route."
