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 be a central figure in the upcoming Ashes series.
Rumors had circulated that Cummins might be unavailable due to a ongoing back issue that was still troubling him.
Earlier indications from the squad suggested no final decision had been made regarding whether he would play, with the Test matches scheduled to begin on November 21 in the WACA.
Bailey expressed that his recovery is on track and remained hopeful about the likelihood of being involved.
"We know that time is getting short and there are permutations around that, aside from the back issue, but further aspects," he commented.
"It's positive. There's strong faith that he'll participate in a significant role. Hopefully from the opening match. If not, we'll adjust."
Previous Setbacks
He was sidelined the ODI and T20 games against New Zealand and India in the previous weeks after scans revealed a lumbar bone stress.
Previous incidents include of recurring issues, with setbacks in 2012-13, 2013-14 and 2015-16 causing him to miss several home seasons in four years.
The bowler mentioned he would be ""aggressive" and "take risks" in his rehabilitation process to make the squad for the series.
He mentioned that he did not know if he had started his bowling workouts as part of his recovery but admitted it was "pressing" for him to regain fitness for the initial match.
Alternative Arrangements
In case of absence, former captain Steve Smith will take over the captaincy.
The talented all-rounder was excluded lately from the national team for their limited-overs matches against India as a preventive step because of an abdominal issue.
Bailey described it as a "minor" injury and stated that he'll feature in the state-level matches, so will be "in a good place to be ready to bowl."
"Extensive planning has gone into developing the strategy for him to take part for the first Test as an dual-role player," Bailey explained.
"He was only going to play the first two ODIs anyway. How he handles the bat in limited-overs, should it hinder progress for a short period, the choice was made to adopt a safer strategy."
