The pace bowler has claimed over 300 dismissals in 71 Test matches with an average of 22.10.
The Australian chief selector the selector has confirmed that pace spearhead Cummins will play a "major part" in the forthcoming England-Australia contest.
There were concerns that the 32-year-old might miss the series due to a ongoing back issue that had not yet healed.
Previous updates from team management suggested no official announcement had been made regarding whether he would play, with the Test matches set to start on the 21st of November in Perth.
The selector shared that Cummins is "building up" and felt positive about his chances of being involved.
"We know that the clock is ticking and there are permutations around that, aside from the back issue, but other factors as well," the selector added.
"The outlook is good. There's strong faith that he's going to play a major part. Hopefully from the opening match. Otherwise, we'll adjust."
Injury History
The captain missed Australia's limited-overs series against both Asian and Trans-Tasman rivals in the previous weeks after medical tests showed a lower back issue.
Previous incidents include of spinal problems, with flare-ups in multiple past seasons forcing him out of several home seasons in four years.
Cummins stated he would be bold in recovery efforts in his comeback strategy to make the squad for the Ashes.
The selector indicated that he did not know if he had started his bowling workouts as part of his recovery but acknowledged it was "becoming urgent" for him to regain fitness for the initial match.
Contingency Plans
If he's unavailable, ex-skipper Smith will take over the captaincy.
All-rounder Cameron Green was withdrawn recently from the ODI lineup for their one-day international series against the Asian giants as a preventive step because of an abdominal issue.
Bailey described it as a "slight concern and confirmed that Green will play in the domestic first-class competition, so will be "well-prepared to resume bowling."
"Considerable effort has gone into building out the plan for him to participate for the initial game as an batting and bowling option," the selector detailed.
"Originally, he'd only feature in the initial matches in any case. How he handles the willow in shorter formats, should it hinder progress for another day, we opted to approach this more conservatively."
