The pace bowler has secured 309 wickets in 71 five-day games with an impressive average.
The Australian chief selector the selector has declared that captain Pat Cummins will have a crucial role in the forthcoming historic rivalry.
There were concerns that the veteran bowler might be unavailable due to a stress fracture in his back that remained unresolved.
Earlier indications from the squad suggested no official announcement had been made regarding Cummins' participation, with the extended contest kicking off on 21 November in the WACA.
Bailey expressed that his recovery is on track and was "optimistic" about the prospects of being involved.
"It's clear that the clock is ticking and there are permutations around that, not just the back issue, but other factors as well," the selector added.
"The outlook is good. We firmly believe that he will feature a significant role. Hopefully it's the first Test. Should that not happen, then we'll pick it up."
Past Concerns
The captain missed Australia's limited-overs series against New Zealand and India recently after examinations confirmed a lower back issue.
There is a track record of back injuries, with flare-ups in several earlier campaigns leading to absences from several home seasons in a limited period.
He emphasized he would be ""aggressive" and "take risks" in his rehabilitation process to secure his spot for the Ashes.
The selector indicated that he did not know if he had started his bowling workouts as part of his recovery but conceded it was "pressing" for him to be fit for the first Test.
Alternative Arrangements
If he's unavailable, veteran batsman Smith will take over the captaincy.
Versatile player Green was excluded lately from the ODI lineup for their one-day international series against India as a safety move because of an abdominal issue.
The selector characterized it as a "slight concern and mentioned that he's scheduled to appear in the state-level matches, so will be "well-prepared to be ready to bowl."
"Extensive planning has gone into creating the schedule for him to be available for the first Test as an dual-role player," the selector detailed.
"He was only going to play the starting games regardless. His aggressive style the cricket bat in white-ball cricket, should it hinder progress for 24 more hours, we just made the decision to take a cautious route."
