Langer’s departure follows media reports that he reacted angrily during a recent meeting with Cricket Australia over his contract and was asked to reapply for the job.
After another meeting on Friday, Cricket Australia said the two sides were involved in important contract discussions.
Langer’s representatives, Dynamic Sports & Entertainment Group (DSEG), said he had resigned effective immediately.
“DSEG confirms that our client Justin Langer has tendered his resignation as Coach of the Australian Men’s Cricket Team this morning,” the company tweeted.
“The resignation follows a meeting with Cricket Australia last night. The resignation is effective immediately.”
Langer’s tenure culminated in a 4-0 thrashing against England in the Ashes series, and he walks away with one of the best overall records since Australia first appointed a full-time coach in 1985. .
However, there were frequent speculations that he didn’t have the full backing of the dressing room.
Cricket Australia’s senior players and managers met last year as Langer’s intense coaching style rubbed the players the wrong way.
Australian Test captain Pat Cummins recently praised Langer for a “fantastic” job but said it was right for Cricket Australia to carry out an evaluation process before making a decision on renewing his contract.
Langer, 51, is leaving less than a month before Australia’s tour of Pakistan, their first visit to the country in 24 years.
He took over as coach following the ball-tampering scandal in South Africa in 2018 and his contract was due to expire in June.
Langer, who has won 105 Test caps, said last month he was proud of the team’s performance.
“Whatever happens from now on, we can all be incredibly proud of this little period,” he said on Australian radio SEN. [L4N2OZ321]
“We had two missions: to win the World Cup (Twenty20) and to win the Ashes.
“To do this in such a short time is a monumental effort and we’re all really happy with it, we’re all really happy about it, we’re all really, really proud of it.
“I’m sitting here right now feeling really satisfied with the last two sets.”
