The pace bowler has secured over 300 dismissals in 71 appearances with an stellar bowling average.
The Australian chief selector the selector has stated that skipper Cummins will have a crucial role in this winter's Ashes series.
Rumors had circulated that the veteran bowler might sit out due to a ongoing back issue that had not yet healed.
Earlier indications from the Australian camp suggested no final decision had been made regarding his involvement, with the extended contest scheduled to begin on the 21st of November in Perth.
The selector shared that his recovery is on track and remained hopeful about his chances of taking part.
"It's clear that time is getting short and various factors involved, not just the physical problem, but further aspects," Bailey remarked.
"It's positive. We firmly believe that he will feature a significant role. With luck from the opening match. If not, then we'll pick it up."
Previous Setbacks
He was sidelined the ODI and T20 games against New Zealand and India last month after scans revealed a stress reaction in his back.
There is a track record of spinal problems, with setbacks in 2012-13, 2013-14 and 2015-16 leading to absences from three Australian summers in four years.
He emphasized he would be proactive in his approach in his comeback strategy to ensure his availability for the series.
Bailey noted that it was unclear if he had started his bowling workouts as part of his recovery but admitted it was "becoming urgent" for him to regain fitness for the first Test.
Alternative Arrangements
In case of absence, former captain Steve Smith will lead the side.
The talented all-rounder was excluded lately from the national team for their limited-overs matches against the subcontinent side as a preventive step because of an abdominal issue.
Bailey described it as a "minor" injury and stated that Green will play in the domestic first-class competition, so will be "ideally positioned to be ready to bowl."
"We put so much time has gone into developing the strategy for him to participate for the first Test as an all-rounder," the selector detailed.
"He was only going to play the first two ODIs in any case. The way he swings the bat in limited-overs, even if it just sets him back for a short period, we just made the decision to approach this more conservatively."
