The pace bowler has claimed 309 wickets in 71 Test matches with an stellar bowling average.
The Australian chief selector George Bailey has confirmed that captain Pat Cummins will play a "major part" in the forthcoming Ashes series.
Speculation had been growing that the veteran bowler might miss the series due to a stress fracture in his back that remained unresolved.
Earlier indications from team management suggested no official announcement had been made regarding Cummins' participation, with the extended contest scheduled to begin on the 21st of November in Perth.
Bailey expressed that his recovery is on track and was "optimistic" about the likelihood of participating.
"We're aware that the window is narrowing and multiple considerations around that, aside from the physical problem, but additional elements," the selector added.
"It's positive. There's strong faith that he's going to play a key capacity. With luck starting in Perth. Should that not happen, we'll reassess."
Past Concerns
Cummins was ruled out the ODI and T20 games against New Zealand and India last month after scans revealed a lower back issue.
He has a history of spinal problems, with recurrences in 2012-13, 2013-14 and 2015-16 leading to absences from multiple domestic campaigns in four years.
The bowler mentioned he would be ""aggressive" and "take risks" in his rehabilitation process to secure his spot for the series.
He mentioned that there was no confirmation if the captain had resumed bowling as part of his comeback but conceded it was "becoming urgent" for him to be fit for the initial match.
Alternative Arrangements
In case of absence, veteran batsman Smith will lead the side.
Versatile player Green was recently pulled out from Australia's squad for their one-day international series against India as a preventive step because of discomfort in his torso.
Bailey described it as a "small issue and mentioned that he'll feature in the domestic first-class competition, so will be "well-prepared to be ready to bowl."
"Extensive planning has gone into building out the plan for him to participate for the initial game as an batting and bowling option," Bailey explained.
"Originally, he'd only feature in the first two ODIs anyway. His aggressive style the willow in shorter formats, if it causes any delay for 24 more hours, we just made the decision to take a cautious route."
