The pace bowler has claimed 309 wickets in 71 appearances with an average of 22.10.
Australia's selection chief George Bailey has confirmed that skipper Cummins will have a crucial role in the upcoming Ashes series.
Speculation had been growing that Cummins might sit out due to a stress fracture in his back that remained unresolved.
Previous updates from the Australian camp suggested no official announcement had been made regarding whether he would play, with the extended contest kicking off on the 21st of November in the WACA.
The selector shared that the captain is progressing and remained hopeful about the likelihood of participating.
"We're aware that the window is narrowing and multiple considerations around that, not just his injury, but further aspects," he commented.
"We're encouraged. There's strong faith that he'll participate in a key capacity. Ideally from the opening match. If not, then we'll pick it up."
Past Concerns
The captain missed the ODI and T20 games against New Zealand and India in the previous weeks after scans revealed a stress reaction in his back.
There is a track record of spinal problems, with recurrences in multiple past seasons forcing him out of multiple domestic campaigns in four years.
He emphasized he would be proactive in his approach in his comeback strategy to secure his spot for the contest.
Bailey noted that it was unclear if he had started his bowling workouts as part of his recovery but admitted it was "becoming urgent" for him to be fit for the first Test.
Contingency Plans
In case of absence, veteran batsman Smith will take over the captaincy.
All-rounder Cameron Green was recently pulled out from the national team for their one-day international series against the subcontinent side as a precautionary measure because of discomfort in his torso.
He labeled it as a "small issue and stated that he'll feature in the domestic first-class competition, so will be "ideally positioned to be ready to bowl."
"Extensive planning has gone into developing the strategy for him to be available 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 24 more hours, we just made the decision to approach this more conservatively."
