Steve Waugh believes Pat Cummins would be the "logical choice" to replace the disgraced Tim Paine as Australia Test captain.
Paine sensationally resigned in shame on Friday and was reduced to tears as he apologised for being embroiled in a sexting scandal.
The wicketkeeper, who is married with two children, revealed the decision was based on an explicit text exchange with a female former Cricket Tasmania colleague in 2017.
Vice-captain Cummins is expected to take over from Paine, who will still be available for selection to face England.
Former Australia skipper Waugh endorsed paceman Cummins to step up.
"Pat Cummins is definitely the front-runner to lead the side in Brisbane for the first Test, he's the vice-captain and there is a lot of talk of him taking over Tim Paine sooner or later even without this incident. So, I think he is the logical choice," Waugh told WA Today.
"For the vice-captain, I don't know, someone like a Steve Smith might be a good vice-captain, he's experienced."
Mark Taylor is another ex-Australia captain to back Cummins for the role three years after Smith's reign as skipper ended due to the Newlands ball-tampering scandal.
"I think CA [Cricket Australia] will probably want to go for someone fresh and clean. The timing will make it a more comfortable decision for CA to make Pat the captain," Taylor told The Age and The Sydney Morning Herald.
"It will be hard to go back after another controversy to Steve. I know Pat very well, he's a terrific fella. I think it is harder for a quick bowler to be captain. In terms of leadership he will be very good because he’s a good, solid human being."
Australia batter Travis Head thinks Cummins would be a good appointment.
"Obviously Pat’s been well spoken about, named as vice-captain, it's hard to go past him, or give him the opportunity to," he said.
"He's someone who oozes leadership, not only in the way he presents himself and speaks and the way he goes about things and the way he trains, but also when he's on the field."
