The pace bowler has taken 309 Test scalps in 71 five-day games with an impressive average.
Australia's chief selector Bailey has stated that captain Pat Cummins will have a crucial role in the upcoming historic rivalry.
Speculation had been growing that the veteran bowler might sit out due to a stress fracture in his back that remained unresolved.
Previous updates from the squad suggested no official announcement had been made regarding Cummins' participation, with the five-Test series kicking off on November 21 in Perth.
The selector shared that his recovery is on track and remained hopeful about the likelihood of participating.
"It's clear that time is getting short and multiple considerations around that, not just the back issue, but other factors as well," he commented.
"The outlook is good. There's strong faith that he's going to play a major part. Hopefully from the opening match. If not, we'll reassess."
Past Concerns
He was sidelined Australia's limited-overs series against both Asian and Trans-Tasman rivals recently after scans revealed a lumbar bone stress.
Previous incidents include of recurring issues, with recurrences in 2012-13, 2013-14 and 2015-16 forcing him out of multiple domestic campaigns in a limited period.
The bowler mentioned he would be proactive in his approach in his comeback strategy to secure his spot for the series.
Bailey noted that he did not know if the captain had resumed bowling as part of his comeback but admitted it was "getting tight" for him to regain fitness for the initial match.
Contingency Plans
In case of absence, former captain Steve Smith will assume leadership.
Versatile player Green was withdrawn recently from the national team for their ODI contests against the Asian giants as a safety move because of an abdominal issue.
Bailey described it as a "minor" injury and mentioned that Green will play in the domestic first-class competition, so will be "in a good place to be ready to bowl."
"Extensive planning has gone into building out the plan for him to be available for the initial game as an dual-role player," the selector detailed.
"Originally, he'd only feature in the starting games regardless. His aggressive style the willow in shorter formats, even if it just sets him back for a short period, we just made the decision to take a cautious route."
