The pace bowler has secured 309 Test scalps in 71 appearances with an average of 22.10.
The Australian chief selector George Bailey has confirmed that skipper Cummins will have a crucial role in the upcoming historic rivalry.
Rumors had circulated that Cummins might sit out due to a ongoing back issue that was still troubling him.
Previous updates from the squad suggested no final decision had been made regarding his involvement, with the Test matches set to start on 21 November in Perth.
The selector shared that Cummins is "building up" and remained hopeful about the prospects of taking part.
"It's clear that the clock is ticking and there are permutations around that, not just the physical problem, but additional elements," Bailey remarked.
"We're encouraged. There's strong faith that he's going to play a key capacity. Hopefully it's the first Test. Otherwise, we'll reassess."
Previous Setbacks
The captain missed the ODI and T20 games against India and New Zealand recently after scans revealed a lumbar bone stress.
Previous incidents include of recurring issues, with setbacks in 2012-13, 2013-14 and 2015-16 forcing him out of three Australian summers in a limited period.
He emphasized he would be ""aggressive" and "take risks" in his rehabilitation process to ensure his availability for the contest.
The selector indicated that he did not know if the captain had resumed bowling as part of his rehabilitation but conceded it was "getting tight" for him to recover fully for the initial match.
Contingency Plans
Should Cummins not be fit, veteran batsman Smith will assume leadership.
The talented all-rounder was excluded lately from Australia's squad for their one-day international series against India as a safety move because of an abdominal issue.
Bailey described it as a "minor" injury and mentioned that Green will play in the Sheffield Shield, so will be "well-prepared to deliver overs."
"Considerable effort has gone into building out the plan for him to participate for the first Test as an dual-role player," Bailey explained.
"Originally, he'd only feature in the initial matches in any case. The way he swings the bat in limited-overs, even if it just sets him back for a short period, the choice was made to take a cautious route."
