The Australian skipper has claimed 309 wickets in 71 five-day games with an average of 22.10.
Australia's chair of selectors the selector has declared that pace spearhead Cummins will have a crucial role in the upcoming England-Australia contest.
Rumors had circulated that Cummins might be unavailable due to a persistent back stress problem that was still troubling him.
Previous updates from the Australian camp suggested no final decision had been made regarding Cummins' participation, with the five-Test series kicking off on 21 November in Perth.
Bailey expressed that Cummins is "building up" and remained hopeful about the likelihood of taking part.
"It's clear that the window is narrowing and there are permutations at play, aside from his injury, but additional elements," he commented.
"The outlook is good. There's strong faith that he will feature a significant role. Ideally from the opening match. Otherwise, we'll reassess."
Past Concerns
The captain missed the white-ball matches against both Asian and Trans-Tasman rivals recently after medical tests showed a lower back issue.
There is a track record of spinal problems, with recurrences 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 ensure his availability for the Ashes.
He mentioned that he did not know if the captain had resumed bowling as part of his comeback but admitted it was "pressing" for him to regain fitness for the opener.
Contingency Plans
If he's unavailable, veteran batsman Smith will assume leadership.
All-rounder Cameron Green was withdrawn recently from the ODI lineup for their ODI contests against the Asian giants as a safety move because of an abdominal issue.
He labeled it as a "slight concern and confirmed that he's scheduled to appear in the domestic first-class competition, so will be "in a good place to deliver overs."
"We put so much time has gone into building out the plan for him to participate for the opening match as an dual-role player," he elaborated.
"Originally, he'd only feature in the starting games regardless. His aggressive style the cricket bat in white-ball cricket, if it causes any delay for 24 more hours, the choice was made to approach this more conservatively."
