The pace bowler has secured 309 Test scalps in 71 appearances with an impressive average.
The Australian chief selector the selector has stated that skipper Cummins will have a crucial role in the upcoming Ashes series.
There were concerns that the 32-year-old might be unavailable due to a persistent back stress problem that had not yet healed.
Previous updates from the squad suggested no definitive call had been made regarding his involvement, with the Test matches set to start on 21 November in the WACA.
He revealed that Cummins is "building up" and remained hopeful about the prospects of being involved.
"We know that the clock is ticking and multiple considerations around that, aside from the physical problem, but further aspects," the selector added.
"It's positive. [We are] really confident that he will feature a key capacity. Hopefully starting in Perth. Should that not happen, we'll adjust."
Previous Setbacks
He was sidelined Australia's limited-overs series against New Zealand and India recently after examinations confirmed a stress reaction in his back.
There is a track record of spinal problems, with recurrences in multiple past seasons causing him to miss several home seasons in a short span.
Cummins stated he would be ""aggressive" and "take risks" in his rehabilitation process to secure his spot for the contest.
The selector indicated that he did not know if he had started his bowling workouts as part of his comeback but acknowledged it was "pressing" for him to recover fully for the opener.
Alternative Arrangements
In case of absence, ex-skipper Smith will assume leadership.
All-rounder Cameron Green was withdrawn recently from the ODI lineup for their one-day international series against the subcontinent side as a safety move because of soreness in his side.
Bailey described it as a "slight concern and stated that he'll feature in the Sheffield Shield, so will be "well-prepared to be ready to bowl."
"Considerable effort has gone into building out the plan for him to take part for the opening match as an batting and bowling option," he elaborated.
"His involvement was limited to the first two ODIs in any case. His aggressive style the cricket bat in white-ball cricket, should it hinder progress for another day, the choice was made to approach this more conservatively."
