The pace bowler has secured 309 Test scalps in 71 Test matches with an stellar bowling average.
Australia's chair of selectors George Bailey has confirmed that skipper Cummins will play a "major part" in this winter's England-Australia contest.
Speculation had been growing that Cummins might sit out due to a ongoing back issue that remained unresolved.
Previous updates from team management suggested no official announcement had been made regarding his involvement, with the five-Test series kicking off on November 21 in the WACA.
Bailey expressed that the captain is progressing and felt positive about his chances of being involved.
"It's clear that the window is narrowing and various factors around that, not only the back issue, but additional elements," he commented.
"We're encouraged. We firmly believe that he's going to play a significant role. With luck starting in Perth. If not, we'll reassess."
Injury History
The captain missed the ODI and T20 games against both Asian and Trans-Tasman rivals recently after scans revealed a lower back issue.
He has a history of back injuries, with flare-ups in 2012-13, 2013-14 and 2015-16 causing him to miss multiple domestic campaigns in a limited period.
The bowler mentioned he would be ""aggressive" and "take risks" in his recovery plan to secure his spot for the Ashes.
He mentioned that it was unclear if Cummins had begun bowling as part of his comeback but conceded it was "pressing" for him to be fit for the opener.
Contingency Plans
Should Cummins not be fit, ex-skipper Smith will assume leadership.
The talented all-rounder was excluded lately from the ODI lineup for their one-day international series against the Asian giants as a precautionary measure because of an abdominal issue.
Bailey described it as a "slight concern and mentioned that he's scheduled to appear in the Sheffield Shield, so will be "in a good place to be ready to bowl."
"We put so much time has gone into creating the schedule for him to be available for the initial game as an all-rounder," the selector detailed.
"He was only going to play the first two ODIs in any case. His aggressive style the cricket bat in white-ball cricket, if it causes any delay for a short period, the choice was made to take a cautious route."
