I didn't have Australia winning it because:
1) Home teams historically don't do that well
2) No front line spinner
3) All batters give you a chance more or less
4) Injury prone pacers
5) Some of their seamers can be erratic
6) They were built up by some as tournament favourites for Bangladesh 2014, saw what happened

Still not as good as they think they are:

Won 1 of their last 15 Tests in the sub-continent.
Not won ICC World Twenty20 in 5 attempts.
Last 4 times played Test series in England not won in 2005, 2009, 2010 (Pak) and 2013.

No ton in 17 Tests. Just 9 50s.
