"That will be it. It will be a case of too much time, too much travel. For me, I've really enjoyed the role and (am) loving it. We'll just get to that point and work out what we do from there," cricket.com.au quoted Lehmann, as saying.
Lehmann, who is currently managing the national side in all formats of the game, has recently spoken about the demanding nature of his job and indicated earlier that 2019 would be his last year at the helm.
In October, Lehmann had said the packed international cricket calendar may leave him with no choice but to hand over the responsibility of the country's limited-over sides and focus solely on Tests.
