The pace bowler has secured 309 Test scalps in 71 five-day games with an impressive average.
The Australian selection chief the selector has stated that pace spearhead Cummins will be a central figure in the forthcoming historic rivalry.
Speculation had been growing that the veteran bowler might miss the series 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 extended contest scheduled to begin on November 21 in the WACA.
He revealed that his recovery is on track and was "optimistic" about the likelihood of being involved.
"We're aware that the clock is ticking and multiple considerations around that, aside from the physical problem, but other factors as well," the selector added.
"The outlook is good. There's strong faith that he will feature a significant role. Ideally from the opening match. Otherwise, then we'll pick it up."
Injury History
Cummins was ruled out the ODI and T20 games against New Zealand and India recently after examinations confirmed a lumbar bone stress.
Previous incidents include of back injuries, with recurrences in multiple past seasons forcing him out of multiple domestic campaigns in a limited period.
He emphasized he would be bold in recovery efforts in his rehabilitation process to make the squad for the Ashes.
Bailey noted that he did not know if the captain had resumed bowling as part of his comeback but admitted it was "getting tight" for him to regain fitness for the opener.
Contingency Plans
If he's unavailable, former captain Steve Smith will assume leadership.
The talented all-rounder was withdrawn recently from the ODI lineup for their limited-overs matches against the Asian giants as a preventive step because of discomfort in his torso.
The selector characterized it as a "minor" injury and confirmed that he'll feature in the state-level matches, so will be "in a good place to deliver overs."
"Extensive planning has gone into developing the strategy for him to take part for the initial game as an batting and bowling option," Bailey explained.
"His involvement was limited to the starting games in any case. His aggressive style the bat in limited-overs, should it hinder progress for another day, the choice was made to adopt a safer strategy."
