Trevor Bayliss will step in as acting Australian Team Coach for the Twenty20 International series against South Africa later this year.
Australia's series against Pakistan in the United Arab Emirates ends just four days before the South Africa series, which will open Australia's home summer of cricket in early November, begins
Head coach Darren Lehmann will have a week's break to prepare for the 2014/15 season, which culminates with the World Cup, which Australia are co-hosting with New Zealand.
"With Lehmann in the UAE focused on the Test matches, we have appointed Trevor to focus on the Australian T20 team to give them the best chance of winning the KFC T20 International series against South Africa," Cricket Australia's (CA) Pat Howard said.
"At the same time, on his return Darren will be able to refocus on bringing the ODI team together in a very big year for 50-over cricket.
"Darren will have had the Zimbabwe tri-series and the UAE tour against Pakistan in quick succession immediately before the biggest ever summer of cricket in Australia, so it’s important he has some time to prepare for each series.
"By appointing an experienced coach such as Trevor to prepare this team he will have longer to bring the team together to compete against South Africa.
"The summer finishes with the ICC Cricket World Cup which is then closely followed by a tour of West Indies and then an Ashes Tour.
"The dual benefit of this decision is that it presents a great opportunity for Trevor to work with the Australian team and is another example of Australian cricket working collectively as ‘one team’.
"The Cricket NSW Chairman and CEO have been very supportive in elevating Trevor and CA thanks them for their support.
"Trevor has obviously coached at international level before and more recently has coached NSW to a Sheffield Shield title. He has won the BBL 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."
Lehmann added that although he always wanted to coach every match the Australian team played, he understands the importance of planning and preparation given the huge series and tournaments coming up.
"We’ve got an absolutely huge period coming up. As soon as the tour to Zimbabwe starts in late August this year, we won’t then finish until after the 2015-16 Australian summer in March 2016; it’s pretty much non-stop," he said.
"So with that in mind it’s important as head coach that we plan and prepare as well as we possibly can.
"Trevor is a very good coach with international experience and has led NSW and the Sydney Sixers extremely well so I have no worries handing the team over to him; the players might actually enjoy having a different voice for these matches.
"Given the schedule, it’s also likely that Australia’s key Test players won’t be part of those opening T20 matches, giving them time to get ready and prepare for the one-day and Tests that follow."
Bayliss, who coached Sri Lanka between 2007 and 2011, when they finished as World Cup runners-up, added:
"I’m very grateful for the opportunity to work with some of Australia’s best T20 players.
"Of course it will be hard to leave NSW at the start of the season, but I’m very much looking forward to this opportunity and know that the Blues will be well looked after while I’m away," he added.
