He has lost his pace and form and don't deserves place in test squad. Don't go over his performance in practice match. International cricket and practice matches are different things.
still australia will win , most of the time we have seen the player who perform in practice match dont perform in main match, like rohit sharma performing well in practice match but flop in T20 match
without binga who returned back to form in the practise match the aussies are really gonna struggle as england at the moment looks a much balanced side
