The pace bowler has secured 309 wickets in 71 Test matches with an impressive average.
The Australian chair of selectors George Bailey has confirmed that pace spearhead Cummins will have a crucial role in the upcoming England-Australia contest.
Rumors had circulated that the 32-year-old might be unavailable due to a ongoing back issue that was still troubling him.
Previous updates from the squad suggested no official announcement had been made regarding Cummins' participation, with the five-Test series kicking off on November 21 in Perth.
The selector shared that Cummins is "building up" and felt positive about the prospects of being involved.
"We're aware that the window is narrowing and multiple considerations involved, not just the physical problem, but other factors as well," Bailey remarked.
"It's positive. There's strong faith that he's going to play a significant role. Ideally it's the first Test. Otherwise, we'll adjust."
Past Concerns
Cummins was ruled out Australia's limited-overs series against New Zealand and India last month after examinations confirmed a lumbar bone stress.
Previous incidents include of recurring issues, with recurrences in 2012-13, 2013-14 and 2015-16 leading to absences from multiple domestic campaigns in a limited period.
The bowler mentioned he would be bold in recovery efforts in his recovery plan to make the squad for the series.
The selector indicated that there was no confirmation if he had started his bowling workouts as part of his comeback but conceded it was "getting tight" for him to regain fitness for the first Test.
Backup Options
In case of absence, former captain Steve Smith will take over the captaincy.
The talented all-rounder was excluded lately from the national team for their ODI contests against the Asian giants as a precautionary measure because of soreness in his side.
He labeled it as a "small issue and confirmed that he'll feature in the Sheffield Shield, so will be "in a good place to be ready to bowl."
"Extensive planning has gone into building out the plan for him to participate for the opening match as an all-rounder," the selector detailed.
"Originally, he'd only feature in the first two ODIs in any case. The way he swings the bat in limited-overs, should it hinder progress for another day, the choice was made to adopt a safer strategy."
