Justin Langer acknowledged he'd lost the support of some players and staff in his resignation letter to Cricket Australia.
The former coach walked away from the job on Saturday after knocking back a six-month contract to stay in the role through to the T20 World Cup.
Cricket Australia, as well as the players, have come under fire for their handling of the situation and failure to support the Ashes and T20 World Cup winning coach.
Langer's resignation letter has now been revealed by The Australian's Peter Lalor, detailing the rationale for the 51-year-old's decision.
The former Test opening batter said he was proud of what he had achieved but felt the decision to walk away was best for the team.
"I want people to know I am happy with my decision and proud of what I have achieved," Langer wrote.
"There has been a great deal of media speculation on my future as the Australian men's cricket coach over the last 12 months and this has taken an enormous toll on my family. I hope through this time, and throughout my tenure, I have held myself with integrity and dignity.
"Last night I was offered a short-term contract until the end of the T20 World Cup in Australia, with the sentiment of 'going out on a high'.
"After careful consideration I have decided not to accept this contract renewal, and as a result I believe it is in everyone's best interests for the Australian cricket team to begin the next chapter immediately.
"If media reports are correct, several senior players and a couple of support staff don't support me moving forward, and it is now apparent the CA board, and you Nick, are also keen to see the team move in another direction. I respect that decision."
Langer appeared to lose support of key members of the playing group mid-way through last year as his style of management began to wear thin.
"My life has been built on values of honesty, respect, trust, truth, and performance and if that comes across as 'too intense' at times, I apologise," he continued.

A host of Langer's former teammates have come out in criticism of the current playing group's perceived treatment of the coach.
Mitchell Johnson said captain Pat Cummins was "gutless" in failing to support Langer, while Matthew Hayden was also critical of the skipper.
Ricky Ponting, Adam Gilchrist and Steve Waugh are also among those to have publicly questioned Cricket Australia's handling of the situation.
Former assistant coach Andrew McDonald has been elevated to head coach in an interim capacity.
