The Australian skipper has taken 309 wickets in 71 five-day games with an impressive average.
The Australian chief selector Bailey has stated that skipper Cummins will play a "major part" in the upcoming Ashes series.
There were concerns that the 32-year-old might be unavailable due to a stress fracture in his back that remained unresolved.
Previous updates from team management suggested no final decision had been made regarding whether he would play, with the five-Test series scheduled to begin on the 21st of November in Western Australia.
Bailey expressed that his recovery is on track and remained hopeful about his chances of taking part.
"We know that the clock is ticking and there are permutations involved, aside from the physical problem, but further aspects," Bailey remarked.
"The outlook is good. [We are] really confident that he will feature a major part. Hopefully from the opening match. Should that not happen, we'll adjust."
Injury History
Cummins was ruled out the ODI and T20 games against India and New Zealand in the previous weeks after examinations confirmed a stress reaction in his back.
There is a track record of recurring issues, with flare-ups in several earlier campaigns forcing him out of three Australian summers in a short span.
He emphasized he would be ""aggressive" and "take risks" in his recovery plan to secure his spot for the contest.
Bailey noted that he did not know if the captain had resumed bowling as part of his recovery but acknowledged it was "getting tight" for him to recover fully for the first Test.
Backup Options
In case of absence, ex-skipper Smith will lead the side.
Versatile player Green was withdrawn recently from Australia's squad for their ODI contests against the subcontinent side as a safety move because of soreness in his side.
He labeled it as a "small issue and confirmed that he's scheduled to appear in the state-level matches, so will be "ideally positioned to be ready to bowl."
"We put so much time has gone into building out the plan for him to be available for the initial game as an dual-role player," Bailey explained.
"His involvement was limited to the initial matches in any case. How he handles the cricket bat in white-ball cricket, if it causes any delay for 24 more hours, we just made the decision to approach this more conservatively."
