The pace bowler has claimed over 300 dismissals in 71 Test matches with an average of 22.10.
The Australian chair of selectors the selector has declared that skipper Cummins will be a central figure in this winter's Ashes series.
Speculation had been growing that the veteran bowler might sit out due to a stress fracture in his back that was still troubling him.
Earlier indications from team management suggested no official announcement had been made regarding Cummins' participation, with the Test matches scheduled to begin on November 21 in the WACA.
The selector shared that the captain is progressing and felt positive about the likelihood of being involved.
"It's clear that the window is narrowing and multiple considerations around that, not just his injury, but other factors as well," he commented.
"The outlook is good. We firmly believe that he will feature a key capacity. Hopefully from the opening match. Should that not happen, then we'll pick it up."
Injury History
He was sidelined Australia's limited-overs series against both Asian and Trans-Tasman rivals last month after scans revealed a lumbar bone stress.
There is a track record of spinal problems, with recurrences in 2012-13, 2013-14 and 2015-16 forcing him out of multiple domestic campaigns in four years.
Cummins stated he would be ""aggressive" and "take risks" in his rehabilitation process to secure his spot for the contest.
The selector indicated that there was no confirmation if he had started his bowling workouts as part of his rehabilitation but acknowledged it was "pressing" for him to regain fitness for the initial match.
Alternative Arrangements
In case of absence, veteran batsman Smith will assume leadership.
All-rounder Cameron Green was recently pulled out from the ODI lineup for their ODI contests against the subcontinent side as a preventive step because of soreness in his side.
Bailey described it as a "slight concern and confirmed that Green will play in the domestic first-class competition, so will be "in a good place to resume bowling."
"We put so much time has gone into creating the schedule for him to be available for the initial game as an all-rounder," the selector detailed.
"His involvement was limited to the starting games regardless. How he handles the cricket bat in white-ball cricket, even if it just sets him back for a short period, the choice was made to adopt a safer strategy."
