Australia chance for Bayliss
Trevor Bayliss will take charge of Australia’s Twenty20 squad when they face South Africa on home soil in November.
Bayliss, the current coach of New South Wales, will temporarily stand in for head coach Darren Lehmann who takes a short break at the start of a busy season.
Cricket Australia said in a statement: "Bayliss has won the Big Bash and Champions League Twenty20 with the Sixers and an IPL title with Kolkata, so we know that while Darren is away the team will be in good hands."
The matches, which open Australia's home season, will be played only days after Lehmann and Australia return from a series against Pakistan in the United Arab Emirates.
From the start of Australia's tour to Zimbabwe in August, Lehmann has no major breaks until the end of the 2015/16 season.
Meanwhile, Cricket Australia insists it will be sending a full-strength team to Zimbabwe for the one-day tri-nation series that also includes South Africa.
And Lehmann has given batsman David Warner his blessing to miss the tour as he prepares to become a father for the first time.
However, Cricket Australia says they have no intention of resting other frontline players.
