Australia's selection chief the selector has confirmed that pace spearhead Cummins will have a crucial role in the forthcoming historic rivalry.
There were concerns that Cummins might be unavailable due to a stress fracture in his back that remained unresolved.
Previous updates from team management suggested no final decision had been made regarding whether he would play, with the extended contest kicking off on November 21 in Perth.
Bailey expressed that Cummins is "building up" and felt positive about the prospects of being involved.
"We know that time is getting short and various factors involved, aside from the physical problem, but further aspects," Bailey remarked.
"The outlook is good. There's strong faith that he will feature a significant role. With luck it's the first Test. Otherwise, we'll adjust."

Previous incidents include of recurring issues, with setbacks in several earlier campaigns leading to absences from multiple domestic campaigns in a limited period.
Cummins stated he would be bold in recovery efforts in his rehabilitation process to secure his spot for the Ashes.
He mentioned that there was no confirmation if he had started his bowling workouts as part of his rehabilitation but acknowledged it was "becoming urgent" for him to recover fully for the initial match.
Alternative Arrangements

Versatile player Green was withdrawn recently from the national team for their ODI contests against the subcontinent side as a precautionary measure because of soreness in his side.
The selector characterized it as a "slight concern and confirmed that he's scheduled to appear in the Sheffield Shield, so will be "ideally positioned to be ready to bowl."
"Extensive planning has gone into creating the schedule for him to be available for the opening match as an dual-role player," Bailey explained.
"His involvement was limited to the first two ODIs in any case. His aggressive style the bat in limited-overs, should it hinder progress for a short period, we just made the decision to approach this more conservatively."
