The pace bowler has secured 309 Test scalps in 71 appearances with an average of 22.10.
Australia's chief selector George Bailey has stated that skipper Cummins will have a crucial role in the upcoming England-Australia contest.
There were concerns that the 32-year-old might miss the series due to a ongoing back issue that was still troubling him.
Earlier indications from team management suggested no final decision had been made regarding his involvement, with the five-Test series scheduled to begin on the 21st of November in the WACA.
Bailey expressed that the captain is progressing and felt positive about the prospects of participating.
"We know that the window is narrowing and multiple considerations at play, not only the physical problem, but other factors as well," he commented.
"The outlook is good. [We are] really confident that he'll participate in a major part. Ideally from the opening match. If not, we'll reassess."
Injury History
He was sidelined Australia's limited-overs series against both Asian and Trans-Tasman rivals last month after scans revealed a lower back issue.
Previous incidents include of back injuries, with setbacks in several earlier campaigns forcing him out of three Australian summers in a limited period.
The bowler mentioned he would be ""aggressive" and "take risks" in his recovery plan to secure his spot for the series.
Bailey noted that there was no confirmation if he had started his bowling workouts as part of his comeback but conceded it was "becoming urgent" for him to recover fully for the opener.
Backup Options
If he's unavailable, ex-skipper Smith will take over the captaincy.
The talented all-rounder was recently pulled out from the ODI lineup for their limited-overs matches against India as a safety move because of soreness in his side.
He labeled it as a "slight concern and confirmed that he's scheduled to appear in the domestic first-class competition, so will be "ideally positioned to deliver overs."
"We put so much time has gone into creating the schedule for him to be available for the opening match as an batting and bowling option," Bailey explained.
"He was only going to play the first two ODIs regardless. His aggressive style the cricket bat in white-ball cricket, even if it just sets him back for a short period, we opted to adopt a safer strategy."
