The pace bowler has taken 309 wickets in 71 five-day games with an stellar bowling average.
Australia's chief selector George Bailey has confirmed that pace spearhead Cummins will play a "major part" in the upcoming England-Australia contest.
Speculation had been growing that the 32-year-old might sit out due to a persistent back stress problem that remained unresolved.
Initial reports from the squad suggested no official announcement had been made regarding his involvement, with the Test matches kicking off on 21 November in the WACA.
He revealed that his recovery is on track and felt positive about the prospects of taking part.
"We're aware that time is getting short and various factors around that, not only the physical problem, but further aspects," Bailey remarked.
"It's positive. There's strong faith that he's going to play a significant role. With luck it's the first Test. Otherwise, then we'll pick it up."
Previous Setbacks
He was sidelined the white-ball matches against both Asian and Trans-Tasman rivals last month after examinations confirmed a stress reaction in his back.
There is a track record of recurring issues, with flare-ups in 2012-13, 2013-14 and 2015-16 leading to absences from several home seasons in a limited period.
He emphasized he would be ""aggressive" and "take risks" in his recovery plan to ensure his availability for the contest.
He mentioned that he did not know if the captain had resumed bowling as part of his recovery but acknowledged it was "becoming urgent" for him to recover fully for the opener.
Alternative Arrangements
Should Cummins not be fit, former captain Steve Smith will take over the captaincy.
All-rounder Cameron Green was withdrawn recently from Australia's squad for their limited-overs matches against the subcontinent side as a safety move because of soreness in his side.
The selector characterized it as a "minor" injury and mentioned that he's scheduled to appear in the Sheffield Shield, so will be "well-prepared to be ready to bowl."
"Extensive planning has gone into building out the plan for him to take part for the opening match as an batting and bowling option," he elaborated.
"He was only going to play the initial matches anyway. His aggressive style the cricket bat in white-ball cricket, even if it just sets him back for a short period, we opted to approach this more conservatively."
