The pace bowler has claimed 309 wickets in 71 Test matches with an stellar bowling average.
Australia's chief selector George Bailey has declared that skipper Cummins will have a crucial role in this winter's historic rivalry.
Speculation had been growing that Cummins might be unavailable due to a persistent back stress problem that was still troubling him.
Initial reports from team management suggested no official announcement had been made regarding whether he would play, with the extended contest kicking off on 21 November in the WACA.
He revealed that his recovery is on track and was "optimistic" about the prospects of being involved.
"It's clear that time is getting short and various factors involved, not just the physical problem, but further aspects," Bailey remarked.
"We're encouraged. We firmly believe that he will feature a major part. Hopefully starting in Perth. Otherwise, then we'll pick it up."
Previous Setbacks
He was sidelined the ODI and T20 games against New Zealand and India recently after examinations confirmed a lumbar bone stress.
Previous incidents include of recurring issues, with flare-ups in several earlier campaigns causing him to miss multiple domestic campaigns in a short span.
He emphasized he would be bold in recovery efforts in his comeback strategy to secure his spot for the contest.
The selector indicated that there was no confirmation if the captain had resumed bowling as part of his comeback but conceded it was "getting tight" for him to regain fitness for the opener.
Contingency Plans
Should Cummins not be fit, former captain Steve Smith will assume leadership.
All-rounder Cameron Green was recently pulled out from Australia's squad for their limited-overs matches against India as a preventive step because of an abdominal issue.
The selector characterized it as a "small issue and confirmed that he'll feature in the Sheffield Shield, so will be "ideally positioned to resume bowling."
"Extensive planning has gone into building out the plan for him to participate for the opening match as an batting and bowling option," he elaborated.
"His involvement was limited to the first two ODIs regardless. His aggressive style the bat in limited-overs, should it hinder progress for another day, we just made the decision to adopt a safer strategy."
