First of all relise your strenghts if you want to beat the world and indias strenth is not fast bowling or all-rounders for sure, main strenght of india is its batting that can demolish any attack if given the confidence
Tendulkar Should be told to attack weather he fails or succeeds either leave his place for other person or even think to come at one or two down but attack from the world go he is most destructive more than sehwag, dhoni believ it, Saurav should be given a chance and should open with sehwag or have wasim jaffar with sehwag is a good option and sachin at one down and rahul to follow, yuvi, kaif and dhoni to follow
And dont think about winning when playing with australia, play to punch them, hit them as hard as possible with your batting and try to hit their seiky at the max you can lose in the process but you may have you pride intact and i assure you they can be beaten with aggression and will power then your talent and stratagies which they will never allow to succeed. Just humilate them or be ready to be humilated.
