The Australian skipper has taken 309 wickets in 71 appearances with an stellar bowling average.
Australia's selection chief Bailey has confirmed that skipper Cummins will have a crucial role in the upcoming England-Australia contest.
There were concerns that the 32-year-old might be unavailable due to a persistent back stress problem that remained unresolved.
Initial reports from the Australian camp suggested no final decision had been made regarding Cummins' participation, with the five-Test series set to start on the 21st of November in the WACA.
He revealed that his recovery is on track and was "optimistic" about the likelihood of taking part.
"It's clear that the clock is ticking and multiple considerations at play, not only his injury, but further aspects," he commented.
"It's positive. [We are] really confident that he will feature a major part. With luck from the opening match. Should that not happen, we'll reassess."
He was sidelined the white-ball matches against both Asian and Trans-Tasman rivals recently after medical tests showed a lower back issue.
Previous incidents include of spinal problems, with setbacks in multiple past seasons forcing him out of three Australian summers in four years.
He emphasized he would be bold in recovery efforts in his comeback strategy to secure his spot for the Ashes.
He mentioned that he did not know if he had started his bowling workouts as part of his rehabilitation but admitted it was "pressing" for him to regain fitness for the opener.
In case of absence, veteran batsman Smith will take over the captaincy.
Versatile player Green was withdrawn recently from the ODI lineup for their one-day international series against the subcontinent side as a preventive step because of discomfort in his torso.
The selector characterized it as a "slight concern and confirmed that he'll feature in the domestic first-class competition, so will be "well-prepared to resume bowling."
"We put so much time has gone into building out the plan for him to take part for the first Test as an all-rounder," Bailey explained.
"Originally, he'd only feature in the starting games in any case. The way he swings the willow in shorter formats, even if it just sets him back for another day, we just made the decision to adopt a safer strategy."
