Regular coach Justin Langer is giving the tour a miss after an intense summer of Test cricket with the reins handed to his assistant Andrew McDonald.
McDonald has had a rapid rise. He was playing in the Twenty20 Big Bash four years ago before turning to coaching and being appointed Langer’s right-hand man in October.
“He’s got great credentials and he’ll keep growing. He’s got a really good opportunity,” Langer told reporters this week.
“I said to him: ‘we’re not reinventing the wheel’. I won’t ring him, I’ll let him go.
“He said ‘I might ring you’. He’ll do a really good job.”
Australia have radically overhauled their squad for the series with in-form batsman Marnus Labuschagne, fresh from an incredible Test summer against Pakistan and New Zealand, set to make his one-day international debut.

Spinner Ashton Agar gets another chance 18 months after his last one-dayer and paceman Josh Hazlewood has been recalled after recovering from injury to once again partner Mitchell Starc and Pat Cummins.
There was no room for high-profile players such as Usman Khawaja, Shaun Marsh, Glenn Maxwell, Marcus Stoinis and Nathan Lyon.
Australia squad: Aaron Finch (capt), Ashton Agar, Alex Carey, Pat Cummins, Peter Handscomb, Josh Hazlewood, Marnus Labuschagne, Kane Richardson, D’Arcy Short, Steve Smith, Mitchell Starc, Ashton Turner, David Warner, Adam Zampa
