The pace bowler has secured 309 Test scalps in 71 appearances with an impressive average.
The Australian chair of selectors the selector has declared that skipper Cummins will have a crucial role in this winter's England-Australia contest.
Rumors had circulated that the 32-year-old might be unavailable due to a persistent back stress problem that was still troubling him.
Earlier indications from the squad suggested no official announcement had been made regarding whether he would play, with the Test matches set to start on 21 November in the WACA.
He revealed that the captain is progressing and was "optimistic" about his chances of participating.
"It's clear that the clock is ticking and there are permutations involved, aside from the back issue, but other factors as well," the selector added.
"We're encouraged. We firmly believe that he's going to play a key capacity. With luck from the opening match. Otherwise, we'll adjust."
Injury History
He was sidelined the white-ball matches against both Asian and Trans-Tasman rivals in the previous weeks after scans revealed a lumbar bone stress.
There is a track record of recurring issues, with flare-ups in multiple past seasons forcing him out of three Australian summers in a short span.
He emphasized he would be proactive in his approach in his recovery plan to make the squad for the contest.
The selector indicated that he did not know if Cummins had begun bowling as part of his rehabilitation but conceded it was "becoming urgent" for him to be fit for the initial match.
Alternative Arrangements
If he's unavailable, ex-skipper Smith will lead the side.
The talented all-rounder was excluded lately from the ODI lineup for their limited-overs matches against the subcontinent side as a preventive step because of discomfort in his torso.
The selector characterized it as a "slight concern and mentioned that he's scheduled to appear in the Sheffield Shield, so will be "in a good place to be ready to bowl."
"Considerable effort has gone into creating the schedule for him to take part for the opening match as an batting and bowling option," he elaborated.
"His involvement was limited to the starting games anyway. His aggressive style the willow in shorter formats, if it causes any delay for 24 more hours, we just made the decision to take a cautious route."
