The pace bowler has claimed 309 wickets in 71 appearances with an average of 22.10.
The Australian chief selector Bailey has stated that skipper Cummins will play a "major part" in the forthcoming historic rivalry.
Speculation had been growing that Cummins might miss the series due to a stress fracture in his back that remained unresolved.
Initial reports from team management suggested no final decision had been made regarding whether he would play, with the five-Test series scheduled to begin on 21 November in the WACA.
He revealed that his recovery is on track and was "optimistic" about the likelihood of participating.
"We're aware that time is getting short and multiple considerations at play, not just the back issue, but additional elements," the selector added.
"The outlook is good. We firmly believe that he'll participate in a major part. Hopefully starting in Perth. Otherwise, then we'll pick it up."
Past Concerns
He was sidelined Australia's limited-overs series against both Asian and Trans-Tasman rivals recently after medical tests showed a lower back issue.
Previous incidents include of back injuries, with flare-ups in 2012-13, 2013-14 and 2015-16 causing him to miss several home seasons in a limited period.
Cummins stated he would be proactive in his approach in his rehabilitation process to ensure his availability for the contest.
The selector indicated that there was no confirmation if Cummins had begun bowling as part of his recovery but admitted it was "getting tight" for him to recover fully for the first Test.
Contingency Plans
If he's unavailable, former captain Steve Smith will lead the side.
All-rounder Cameron Green was excluded lately from the national team for their ODI contests against the subcontinent side as a safety move because of discomfort in his torso.
Bailey described it as a "slight concern and confirmed that he's scheduled to appear in the state-level matches, so will be "in a good place to deliver overs."
"Extensive planning has gone into developing the strategy for him to take part for the first Test as an all-rounder," he elaborated.
"His involvement was limited to the first two ODIs in any case. His aggressive style the willow in shorter formats, should it hinder progress for another day, we opted to approach this more conservatively."
