Andrew McDonald has been appointed as Justin Langer's replacement as the new Australia men's cricket team's head coach on a four-year deal.

McDonald, who has served as Australia's assistant coach since 2019, had been in interim charge of the side since Langer's resignation in February.

The 40-year-old four-time Test all-rounder had been expected to take over from Langer given his popularity among the playing group, who ultimately forced the former coach out.

McDonald took charge of Australia's recent 1-0 three-game Test series victory over Pakistan, while the side lost the ODI series 2-1 and won the sole T20 International.

Cricket Australia (CA) CEO Nick Hockley said that McDonald was the outstanding candidate.

"We interviewed several excellent candidates for this role, which is one of the most important in Australian sport," Hockley said.

"Andrew has already shown he is an outstanding Head Coach and the vision he outlined for the role during the appointment process was both impressive and exciting, making him our clear choice. 

"We are proud of the way the team played and the respect shown throughout the tour of Pakistan under the leadership of Andrew, Pat and Aaron and really pleased Andrew is taking on the role permanently."

McDonald has experience in head coaching, having led Victoria and the Melbourne Renegades previously to all three domestic titles during the 2018-19 season. He has also coached sides in the Indian Premier League and English county cricket.

"I am honoured to be given this incredible opportunity for what is an exciting period ahead," McDonald said.

"The success of the World Cup, the Ashes Series and now Pakistan has been testament to the hard work and leadership of Justin, Pat and Aaron along with the players and the support staff.

"My plan is to build on the growth, depth and experience of the squad while working collectively with the group and across the game.

"There are many challenges in the short term which I know excites the leadership group, the players and the staff. I’d also like to thank my family for their support."

McDonald has been appointed across all three formats but CA noted he may step aside for some white-ball series given the workload of the role.

Australia are due to take on Sri Lanka in all formats in June and July, while they will defend their title on home soil at the T20 World Cup in October and November too.
