Im not sure the aussies wanted to go straight through to the final, I think they would prefer to have the practice in the race-off.
As for deliberately dropping points, maybe the aussies have learnt from a couple of years ago when one of the Poles (KK I think), let Crump go past on the line, only for the Poles to be able to use a tactical joker (brought in Hampel) that cost the aussies the World Cup.
I have a question, how many tactical subs can be used?
