The pace bowler has taken 309 wickets in 71 appearances with an average of 22.10.
The Australian chief selector George Bailey has declared that pace spearhead Cummins will have a crucial role in the upcoming historic rivalry.
There were concerns that the veteran bowler might sit out due to a stress fracture in his back that had not yet healed.
Earlier indications from team management suggested no final decision had been made regarding his involvement, with the extended contest kicking off on 21 November in Perth.
The selector shared that his recovery is on track and remained hopeful about the likelihood of taking part.
"It's clear that time is getting short and various factors around that, aside from his injury, but other factors as well," the selector added.
"The outlook is good. There's strong faith that he's going to play a key capacity. Ideally from the opening match. If not, we'll adjust."
Past Concerns
He was sidelined the ODI and T20 games against India and New Zealand in the previous weeks after scans revealed a lumbar bone stress.
Previous incidents include of back injuries, with flare-ups in several earlier campaigns forcing him out of multiple domestic campaigns in a limited period.
The bowler mentioned he would be bold in recovery efforts in his recovery plan to secure his spot for the contest.
Bailey noted that it was unclear if Cummins had begun bowling as part of his comeback but conceded it was "pressing" for him to recover fully for the opener.
Alternative Arrangements
In case of absence, ex-skipper Smith will assume leadership.
The talented all-rounder was excluded lately from Australia's squad for their ODI contests against India as a precautionary measure because of soreness in his side.
He labeled it as a "slight concern and mentioned that Green will play in the Sheffield Shield, so will be "ideally positioned to be ready to bowl."
"Extensive planning has gone into building out the plan for him to be available for the opening match as an all-rounder," he elaborated.
"He was only going to play the starting games anyway. His aggressive style the cricket bat in white-ball cricket, should it hinder progress for a short period, the choice was made to approach this more conservatively."
