The Australian skipper has secured 309 wickets in 71 five-day games with an impressive average.
Australia's selection chief George Bailey has confirmed that pace spearhead Cummins will play a "major part" in this winter's Ashes series.
There were concerns that Cummins might sit out due to a ongoing back issue that remained unresolved.
Earlier indications from team management suggested no final decision had been made regarding whether he would play, with the Test matches kicking off on the 21st of November in the WACA.
He revealed that Cummins is "building up" and felt positive about his chances of participating.
"We know that the window is narrowing and various factors involved, not just his injury, but other factors as well," Bailey remarked.
"The outlook is good. We firmly believe that he's going to play a significant role. Ideally it's the first Test. Should that not happen, then we'll pick it up."
Previous Setbacks
Cummins was ruled out Australia's limited-overs series against New Zealand and India in the previous weeks after examinations confirmed a lumbar bone stress.
There is a track record of back injuries, with flare-ups in several earlier campaigns leading to absences from multiple domestic campaigns in a short span.
Cummins stated he would be ""aggressive" and "take risks" in his rehabilitation process to make the squad for the contest.
Bailey noted that it was unclear if he had started his bowling workouts as part of his rehabilitation but acknowledged it was "getting tight" for him to regain fitness for the first Test.
Alternative Arrangements
In case of absence, veteran batsman Smith will assume leadership.
The talented all-rounder was recently pulled out from the ODI lineup for their ODI contests against the subcontinent side as a precautionary measure because of soreness in his side.
Bailey described it as a "small issue and mentioned that he'll feature in the state-level matches, so will be "well-prepared to resume bowling."
"Extensive planning has gone into developing the strategy for him to participate for the initial game as an batting and bowling option," Bailey explained.
"His involvement was limited to the first two ODIs anyway. His aggressive style the cricket bat in white-ball cricket, if it causes any delay for a short period, we just made the decision to approach this more conservatively."
