The pace bowler has secured 309 Test scalps in 71 appearances with an stellar bowling average.
The Australian chair of selectors George Bailey has declared that skipper Cummins will be a central figure in the upcoming historic rivalry.
Rumors had circulated that the veteran bowler might miss the series due to a stress fracture in his back that remained unresolved.
Initial reports from the Australian camp suggested no final decision had been made regarding Cummins' participation, with the extended contest scheduled to begin on the 21st of November in the WACA.
The selector shared that Cummins is "building up" and was "optimistic" about his chances of taking part.
"We're aware that the window is narrowing and multiple considerations around that, aside from his injury, but additional elements," he commented.
"It's positive. [We are] really confident that he will feature a major part. Hopefully starting in Perth. Otherwise, then we'll pick it up."
Past Concerns
He was sidelined Australia's limited-overs series against both Asian and Trans-Tasman rivals in the previous weeks after scans revealed a lumbar bone stress.
He has a history of recurring issues, with recurrences in multiple past seasons causing him to miss several home seasons in four years.
Cummins stated he would be bold in recovery efforts in his recovery plan to ensure his availability for the Ashes.
He mentioned that there was no confirmation if he had started his bowling workouts as part of his comeback but acknowledged it was "pressing" for him to regain fitness for the opener.
Backup Options
Should Cummins not be fit, ex-skipper Smith will lead the side.
All-rounder Cameron Green was recently pulled out from Australia's squad for their limited-overs matches against the Asian giants as a safety move because of discomfort in his torso.
The selector characterized it as a "minor" injury and stated that he's scheduled to appear in the Sheffield Shield, so will be "in a good place to deliver overs."
"Considerable effort has gone into creating the schedule for him to participate for the first Test as an batting and bowling option," Bailey explained.
"He was only going to play the initial matches regardless. The way he swings the bat in limited-overs, if it causes any delay for a short period, we opted to take a cautious route."
