Australian batsman Usman Khawaja says Test skipper or white-ball skipper Aaron Finch needs to come out and explain Justin Langer's exit as head coach.
Khawaja, who returned to the Test side during the Ashes after more than two years outside the team, was named in Australia's squad for next month's Pakistan Test series.
The 35-year-old admitted he was sad for "the person" when Langer resigned as Australia head coach amid a messy exit with talk of a player revolt.
Langer spent almost four years in the head coaching role but resigned on Saturday, rejecting a six-month contract extension.
The 51-year-old's exit comes after leading Australia to a 4-0 Ashes triumph and a stunning T20 World Cup victory which has raised eyebrows, yet there have been rumblings of internal issues.
"I just came back in the team two months ago. I've been a little bit out of it, a little bit disconnected, but there's obviously a lot of ex-players coming and talking about the playing group," Khawaja told reporters on Tuesday.
"At some stage, one of the captains, probably Finchy or Patty, will probably have to stand up and answer some questions just to get rid of all the speculation that's going around. To just put an end to it all."
Khawaja said Langer had tried to take on player feedback and insisted "always got along with him".
But several key members of the Australian side, including Cummins, failed to publicly back Langer for a contract extension in the lead-up to Saturday's announcement.
"It's part of speculation which I don't think is really healthy. I just don't want to add to it," Cummins said on Thursday when asked about a contract renewal for Langer.
"That's Cricket Australia's job. It's not my job. I've really loved my time working with JL and we've had an evaluation process. I've been part of that, a lot of other players and staff have been part of that.
"Just like when we get evaluated. I've got huge respect for JL, really like working with him. But it's not my call."
