Would that be #1 ranking in tests, ODI WC win and T20 WC win?
So far only India has achieved the career grand slam. If it manages to win this year's T20 WC and next year's ODI WC then I guess that would also be a calender year Grand Slam!
Australia needs to win T20 WC to achieve the career grand slam. While some of other teams have to do win at least 2 of those.
