The Australian skipper has taken 309 wickets in 71 appearances with an stellar bowling average.
The Australian chair of selectors the selector has confirmed that captain Pat Cummins will have a crucial role in this winter's England-Australia contest.
Speculation had been growing that the 32-year-old might be unavailable due to a ongoing back issue that was still troubling him.
Initial reports from team management suggested no final decision had been made regarding Cummins' participation, with the Test matches kicking off on the 21st of November in Perth.
The selector shared that Cummins is "building up" and felt positive about the likelihood of taking part.
"We're aware that the window is narrowing and multiple considerations at play, not just the physical problem, but other factors as well," Bailey remarked.
"We're encouraged. We firmly believe that he will feature a key capacity. Hopefully it's the first Test. Otherwise, we'll reassess."
Past Concerns
The captain missed the ODI and T20 games against both Asian and Trans-Tasman rivals recently after scans revealed a lumbar bone stress.
Previous incidents include of spinal problems, with recurrences in several earlier campaigns causing him to miss three Australian summers in a limited period.
He emphasized he would be ""aggressive" and "take risks" in his comeback strategy to ensure his availability for the Ashes.
Bailey noted that he did not know if he had started his bowling workouts as part of his rehabilitation but acknowledged it was "becoming urgent" for him to be fit for the first Test.
Contingency Plans
If he's unavailable, veteran batsman Smith will assume leadership.
Versatile player Green was excluded lately from Australia's squad for their ODI contests against the subcontinent side as a preventive step because of an abdominal issue.
Bailey described it as a "slight concern and mentioned that he'll feature in the state-level matches, so will be "ideally positioned to be ready to bowl."
"Considerable effort has gone into creating the schedule for him to be available for the initial game as an batting and bowling option," he elaborated.
"Originally, he'd only feature in the first two ODIs anyway. How he handles the cricket bat in white-ball cricket, even if it just sets him back for a short period, we just made the decision to adopt a safer strategy."
