Granted, for the PSN the numbers will be a bit different, but the population of that area of the world is much smaller then the Americas/Europe/Asia. Australia has a population of only 23 million or so. I think Australia/NZ/Surrounding Area is a long way down the line for their own servers, as unfortunate as that may be.
