I've just done a search for more information regarding this problem, and apparently it is because the austpost module can't provide a valid quote on the first load because it has no way of knowing where the parcel is supposed to be delivered to, or the method of shipping that the user chooses.
This hasn't changed with the ozpost module, so the incompatibilty will still remain with the with ozpost module.
If anyone has any ideas how to overcome this I'll be more than happy to take them into consideration.
Cheers
