The former Australian opener took over from Darren Lehmann, who resigned in March following the ball-tampering scandal in South Africa.
Langer's tenure includes next year's World Cup, two Ashes series and a World T20 on home soil but he has identified victory on Australia's next Test tour of India as the number one long-term goal.
"The public will be disappointed if we don't play good, hard, competitive cricket", said Langer, dressed in a dark suit and tie alongside Cricket Australia boss James Sutherland.
On the carrier graph the newly appointed coach Langer had represented Australia in 105 test matches and eight ODIs, scoring 7,696 test runs, including 23 centuries.
At the end of a year ago, there were reports that he (Ponting) would soon take over as Australia's T20I Head Coach soon.
"If we can keep mentoring and helping them ... and they want to meet the standards of the Australian cricket team, then of course they'd be welcomed back".
Despite widespread criticism of player behaviour, Langer, who will sit on the panel of Rick McCosker's player-led review of team culture, did not believe an overhaul of Australia's aggressive playing style was necessary but accepted modifications were required.
"We will judge ourselves as a great cricket team if we beat India in India", Langer said.
The former Test opener's first assignment with the Kangaroos will be next month's England tour that features five ODIs and a T20 global.
The ex-players hated the WACA (Western Australia Cricket Association), the WACA hated them back, club cricket hated them, WACA hated them back, media hated the WACA, the WACA hated them back - everyone was angry.
He has led the Scorchers to Big Bash League championships on three occasions, the most of any coach, in 2013-14, 2014-15 and 2016-17, and the Warriors to One-Day Cup titles twice, in 2014-15 and 2017-18. "We can all get better at things".
"They are cricket tragics and they're great kids".
"I look back on my career, the Mount Everest moment was 2004 when we finally beat India in India".
"They've made mistakes, we have all made mistakes and we can all get better", he said. "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".
