The pace bowler has secured over 300 dismissals in 71 five-day games with an stellar bowling average.
The Australian chair of selectors George Bailey has stated that skipper Cummins will play a "major part" in this winter's historic rivalry.
Rumors had circulated that the 32-year-old might miss the series due to a ongoing back issue that remained unresolved.
Previous updates from team management suggested no definitive call had been made regarding his involvement, with the Test matches kicking off on November 21 in Perth.
The selector shared that Cummins is "building up" and felt positive about the likelihood of being involved.
"We're aware that the clock is ticking and various factors around that, not only the back issue, but other factors as well," the selector added.
"The outlook is good. [We are] really confident that he'll participate in a key capacity. Hopefully starting in Perth. Should that not happen, we'll reassess."
Past Concerns
The captain missed the white-ball matches against India and New Zealand last month after examinations confirmed a lower back issue.
Previous incidents include of recurring issues, with setbacks in several earlier campaigns leading to absences from several home seasons in four years.
The bowler mentioned he would be proactive in his approach in his recovery plan to secure his spot for the series.
Bailey noted that there was no confirmation if the captain had resumed bowling as part of his recovery but acknowledged it was "getting tight" for him to regain fitness for the initial match.
Contingency Plans
Should Cummins not be fit, veteran batsman Smith will assume leadership.
All-rounder Cameron Green was excluded lately from the national team for their ODI contests against the subcontinent side as a preventive step because of an abdominal issue.
He labeled it as a "minor" injury and mentioned that Green will play in the Sheffield Shield, so will be "ideally positioned to be ready to bowl."
"We put so much time has gone into developing the strategy for him to be available for the initial game as an dual-role player," the selector detailed.
"His involvement was limited to the starting games anyway. His aggressive style the willow in shorter formats, should it hinder progress for 24 more hours, we opted to approach this more conservatively."
