On Thursday he was named head coach, filling a void after Darren Lehmann's resignation in the wake of the ball-tampering scandal at Cape Town that stunned the cricket world and trashed the team's reputation.
He has also been the head coach of Western Australia and has been instrumental in leading Perth Scorchers to titles in the Big Bash League.
I like us all to be tight, not just the players but the support staff, cricket Australia.
But Langer said there was no reason why, after they all "got better" in certain areas, they couldn't play in a team he coaches.
Langer's contract runs for 4 years blanketing two Ashes series, the 2019 World Cup and the World Twenty20.
The whirlwind of controversy that followed saw Bancroft suspended for nine months, while captain Steve Smith and vice captain David Warner received 12 month bans after they admitted to prior knowledge of the incident. That's why it was a surprise they made the mistake they did.
Meanwhile, Virat Kohli's Team India will be traveling to Australia later this year for a full-fledged tour, consisting three-match T20I and ODI series on either side of a four-match Test series.
His staunch refusal to criticise his players publicly, much less sanction them for on-field misconduct, won their loyalty but grew stale for an Australian public increasingly uncomfortable with the team's image.
"He sat me down and said you can either be on the train or you can jump off it".
He also took offence when former England captain Michael Atherton ridiculed the distinctive headgear in 2011, saying it represented a tradition that linked current players to icons such as Donald Bradman.
"We need to modify our behaviours a bit so we're not angry or over aggressive but (we still need to be) aggressive in the mindset we play with the bat and ball. If we do that, I think the outcomes will look after themselves", Langer told a media conference. "We will judge ourselves on whether we're a great cricket team if we beat India in India", he added.
"But ultimately, if I fast forward it, the Indian Test tour in about three or four years' time, to me that's the ultimate". But they are great kids ... we have all made mistakes, we can all get better at things. "In addition to professional development opportunities, this plan has included several coaches [Steve Rixon, Trevor Bayliss, David Saker and Langer] stepping into the head role to relieve Darren at times, and to also provide support roles, including Justin, and forms part of our long-running succession-planning process".
"We firmly believe Justin is the right person to lead this team and have huge confidence in what he will bring to the role".
