No it is not the end of an Australian dominance. Just because we lose 1 match after 17 straight wins it does not mean that we will not be dominant anymore. Thats a stupid thing to say.
And Australia would have won the match if it wasnt for terrible selections. They chose Chris Rogers who has barely played, has not been in form, and was never ever going to be a good test player. They should have chosen Simon Katich, who has been in excellent form scoring at a Bradmanesque average this season, or David Hussey who has been in great form, also scoring 2 centuries against Pakistan or India A(not 100% sure what team).
They also chose Tait who has been injured, and apart from a 7/29 hasnt done anything at FC level this season, instead of Noffke who has been carrying QLD bowling all season, took wickets against Sri Lanka, and has also scored 604 runs @ 55, which would have helped in the first innings when we lost all those wickets, and in the 2nd when we were chasing.
