The pace bowler has secured 309 Test scalps in 71 five-day games with an stellar bowling average.
The Australian chair of selectors the selector has stated that skipper Cummins will have a crucial role in the forthcoming England-Australia contest.
There were concerns that the 32-year-old might sit out due to a ongoing back issue that remained unresolved.
Previous updates from the squad suggested no official announcement had been made regarding whether he would play, with the extended contest set to start on November 21 in Western Australia.
The selector shared that Cummins is "building up" and remained hopeful about his chances of participating.
"We're aware that the clock is ticking and multiple considerations around that, aside from his injury, but other factors as well," he commented.
"The outlook is good. [We are] really confident that he will feature a major part. With luck from the opening match. Should that not happen, we'll reassess."
Past Concerns
The captain missed the white-ball matches against India and New Zealand recently after scans revealed a lumbar bone stress.
There is a track record of recurring issues, with setbacks in multiple past seasons leading to absences from three Australian summers in a short span.
The bowler mentioned he would be bold in recovery efforts in his rehabilitation process to ensure his availability for the contest.
He mentioned that it was unclear if Cummins had begun bowling as part of his recovery but conceded it was "pressing" for him to be fit for the first Test.
Contingency Plans
If he's unavailable, former captain Steve Smith will assume leadership.
The talented all-rounder was recently pulled out from the ODI lineup for their ODI contests against the subcontinent side as a precautionary measure because of soreness in his side.
The selector characterized it as a "slight concern and mentioned that he'll feature in the state-level matches, so will be "ideally positioned to resume bowling."
"We put so much time has gone into creating the schedule for him to participate for the initial game as an batting and bowling option," he elaborated.
"He was only going to play the starting games in any case. How he handles the willow in shorter formats, should it hinder progress for another day, the choice was made to take a cautious route."
