Cutting loose ~25million potential customers might actually be a financially rational for some companies. It's not like we here in Australia are really a very big market on the global stage...

Won't surprise me at all to find some businesses (like perhaps Whisper Systems) who's "doing business in Australia" doesn't actually earn them a single cent, yet will open them up to enormous reputational damage if they continue operating in Australia after this, might just choose to take thier app/service out of the .au app stores...
