The pace bowler has taken over 300 dismissals in 71 five-day games with an average of 22.10.
Australia's chair of selectors George Bailey has stated that pace spearhead Cummins will play a "major part" in the forthcoming historic rivalry.
Rumors had circulated that the veteran bowler might be unavailable due to a ongoing back issue that remained unresolved.
Earlier indications from team management suggested no final decision had been made regarding whether he would play, with the Test matches set to start on the 21st of November in the WACA.
He revealed that Cummins is "building up" and was "optimistic" about his chances of taking part.
"We're aware that time is getting short and multiple considerations around that, not only his injury, but further aspects," Bailey remarked.
"We're encouraged. There's strong faith that he'll participate in a significant role. With luck it's the first Test. Should that not happen, we'll adjust."
Past Concerns
He was sidelined Australia's limited-overs series against India and New Zealand last month after medical tests showed a stress reaction in his back.
Previous incidents include of back injuries, with recurrences in multiple past seasons forcing him out of several home seasons in four years.
Cummins stated he would be proactive in his approach in his rehabilitation process to ensure his availability for the series.
Bailey noted that it was unclear if the captain had resumed bowling as part of his comeback but admitted it was "becoming urgent" for him to regain fitness for the first Test.
Contingency Plans
If he's unavailable, former captain Steve Smith will take over the captaincy.
All-rounder Cameron Green was recently pulled out from Australia's squad for their one-day international series against the Asian giants as a preventive step because of soreness in his side.
The selector characterized it as a "slight concern and confirmed that he's scheduled to appear in the domestic first-class competition, so will be "well-prepared to deliver overs."
"Considerable effort has gone into building out the plan for him to take part for the first Test as an all-rounder," the selector detailed.
"His involvement was limited to the first two ODIs in any case. The way he swings the willow in shorter formats, should it hinder progress for a short period, we opted to approach this more conservatively."
