The pace bowler has taken 309 Test scalps in 71 five-day games with an stellar bowling average.
Australia's selection chief Bailey has stated that captain Pat Cummins will play a "major part" in the upcoming England-Australia contest.
There were concerns that the veteran bowler might be unavailable due to a persistent back stress problem that remained unresolved.
Previous updates from the squad suggested no final decision had been made regarding whether he would play, with the Test matches kicking off on November 21 in the WACA.
He revealed that his recovery is on track and was "optimistic" about the likelihood of taking part.
"We know that time is getting short and various factors at play, not only the physical problem, but further aspects," he commented.
"The outlook is good. We firmly believe that he will feature a significant role. Hopefully starting in Perth. If not, we'll reassess."
Injury History
He was sidelined Australia's limited-overs series against India and New Zealand recently after scans revealed a stress reaction in his back.
There is a track record of recurring issues, with recurrences in 2012-13, 2013-14 and 2015-16 leading to absences from several home seasons in four years.
He emphasized he would be ""aggressive" and "take risks" in his rehabilitation process to make the squad for the contest.
Bailey noted that he did not know if he had started his bowling workouts as part of his rehabilitation but admitted it was "becoming urgent" for him to regain fitness for the initial match.
Backup Options
Should Cummins not be fit, ex-skipper Smith will take over the captaincy.
Versatile player Green was excluded lately from the national team for their limited-overs matches against the Asian giants as a precautionary measure because of soreness in his side.
He labeled it as a "slight concern and stated that he's scheduled to appear in the domestic first-class competition, so will be "ideally positioned to deliver overs."
"Considerable effort has gone into building out the plan for him to take part for the initial game as an batting and bowling option," Bailey explained.
"He was only going to play the initial matches anyway. His aggressive style the willow in shorter formats, should it hinder progress for 24 more hours, we opted to take a cautious route."
