The pace bowler has claimed 309 wickets in 71 five-day games with an impressive average.
Australia's chair of selectors George Bailey has stated that captain Pat Cummins will be a central figure in the forthcoming England-Australia contest.
Speculation had been growing that the veteran bowler might be unavailable due to a persistent back stress problem that remained unresolved.
Earlier indications from the Australian camp suggested no final decision had been made regarding his involvement, with the extended contest kicking off on November 21 in Western Australia.
He revealed that the captain is progressing and was "optimistic" about his chances of taking part.
"We're aware that the clock is ticking and various factors around that, not just the physical problem, but further aspects," Bailey remarked.
"We're encouraged. [We are] really confident that he's going to play a key capacity. With luck it's the first Test. Should that not happen, we'll adjust."
Injury History
Cummins was ruled out the white-ball matches against both Asian and Trans-Tasman rivals last month after examinations confirmed a lower back issue.
Previous incidents include of recurring issues, with recurrences in 2012-13, 2013-14 and 2015-16 leading to absences from several home seasons in a limited period.
The bowler mentioned he would be proactive in his approach in his comeback strategy to make the squad for the Ashes.
He mentioned that he did not know if he had started his bowling workouts as part of his rehabilitation but admitted it was "getting tight" for him to be fit for the opener.
Alternative Arrangements
If he's unavailable, veteran batsman Smith will lead the side.
Versatile player Green was recently pulled out from the ODI lineup for their one-day international series against the Asian giants as a safety move because of an abdominal issue.
The selector characterized it as a "small issue and mentioned that he's scheduled to appear in the domestic first-class competition, so will be "well-prepared to deliver overs."
"Extensive planning has gone into creating the schedule for him to be available for the initial game as an all-rounder," Bailey explained.
"He was only going to play the first two ODIs in any case. How he handles the bat in limited-overs, even if it just sets him back for a short period, we opted to approach this more conservatively."
