The pace bowler has taken over 300 dismissals in 71 appearances with an average of 22.10.
Australia's chair of selectors the selector has confirmed that pace spearhead Cummins will play a "major part" in this winter's Ashes series.
Rumors had circulated that Cummins might be unavailable due to a stress fracture in his back that remained unresolved.
Previous updates from the squad suggested no final decision had been made regarding his involvement, with the extended contest set to start on the 21st of November in the WACA.
Bailey expressed that his recovery is on track and felt positive about the prospects of being involved.
"We know that time is getting short and various factors around that, aside from his injury, but further aspects," the selector added.
"We're encouraged. We firmly believe that he will feature a major part. With luck it's the first Test. If not, we'll reassess."
Past Concerns
The captain missed Australia's limited-overs series against India and New Zealand in the previous weeks after examinations confirmed a lumbar bone stress.
Previous incidents include of recurring issues, with flare-ups in 2012-13, 2013-14 and 2015-16 forcing him out of three Australian summers in a short span.
He emphasized he would be ""aggressive" and "take risks" in his rehabilitation process to make the squad for the Ashes.
The selector indicated that there was no confirmation if Cummins had begun bowling as part of his recovery but acknowledged it was "pressing" for him to be fit for the first Test.
Contingency Plans
Should Cummins not be fit, former captain Steve Smith will assume leadership.
Versatile player Green was withdrawn recently from Australia's squad for their one-day international series against India as a precautionary measure because of an abdominal issue.
Bailey described it as a "minor" injury and stated that he's scheduled to appear in the state-level matches, so will be "ideally positioned to be ready to bowl."
"We put so much time has gone into developing the strategy for him to be available for the opening match as an dual-role player," he elaborated.
"Originally, he'd only feature in the initial matches in any case. The way he swings the willow in shorter formats, if it causes any delay for a short period, we opted to adopt a safer strategy."
