Marsh will be given first crack on winning the top job, with the talented all-rounder named captain for the T20 component of Australia's white-ball tour of South Africa that commences later this month, an ICC report on Monday said.
While Marsh has only been named as skipper for the upcoming South Africa tour, chief selector George Bailey believes the 31-year-old is capable of holding the job on a full-time basis.
"Mitch has long been a senior player within the white-ball structure, with this an opportunity for him to add to his leadership skills at international level," Bailey said.
"We look forward to him taking that step in South Africa," he added.
Marsh will lead a new-look squad for the three-match T20I component of the tour, with selectors naming a host of fresh faces among their squad for what will be their first 20-over matches since last year's T20 World Cup.
All-rounder Aaron Hardie, opening batter Matt Short and left-arm quick Spencer Johnson are all in line for an international debut during the three-match series, with Steve Smith, Marcus Stoinis, Glenn Maxwell, Adam Zampa and Marsh the only players in the squad that played at Australia's most recent T20I last year.
Marsh previously captained Australia to success at the ICC Men's Under-19 Cricket World Cup in New Zealand in 2010 and has experience leading his state Western Australia at domestic level.
