The pace bowler has secured 309 Test scalps in 71 Test matches with an average of 22.10.
Australia's selection chief the selector has stated that skipper Cummins will have a crucial role in this winter's England-Australia contest.
Speculation had been growing that the veteran bowler might be unavailable due to a persistent back stress problem that had not yet healed.
Earlier indications from the squad suggested no final decision had been made regarding his involvement, with the five-Test series set to start on 21 November in Western Australia.
The selector shared that Cummins is "building up" and remained hopeful about his chances of participating.
"It's clear that the clock is ticking and various factors involved, not only his injury, but additional elements," he commented.
"It's positive. We firmly believe that he will feature a key capacity. Ideally from the opening match. If not, we'll adjust."
Previous Setbacks
He was sidelined the ODI and T20 games against India and New Zealand in the previous weeks after medical tests showed a stress reaction in his back.
Previous incidents include of spinal problems, with recurrences in several earlier campaigns forcing him out of three Australian summers in four years.
He emphasized he would be proactive in his approach in his rehabilitation process to ensure his availability for the contest.
The selector indicated that there was no confirmation if the captain had resumed bowling as part of his comeback but acknowledged it was "becoming urgent" for him to recover fully for the opener.
Alternative Arrangements
If he's unavailable, veteran batsman Smith will assume leadership.
All-rounder Cameron Green was recently pulled out from the national team for their ODI contests against the subcontinent side as a safety move because of an abdominal issue.
He labeled it as a "minor" injury and confirmed that he's scheduled to appear in the Sheffield Shield, so will be "ideally positioned to be ready to bowl."
"Extensive planning has gone into building out the plan for him to be available for the opening match as an dual-role player," the selector detailed.
"Originally, he'd only feature in the initial matches anyway. The way he swings the bat in limited-overs, even if it just sets him back for another day, the choice was made to take a cautious route."
