Fallout 3 gets banned in Australia

What is with the UK and AU always banning games. Maybe they should change their rating system, because our mature rating (which is 17+) is 15+ for them. Maybe if they upped their system, less games would get banned. But I really have to feel bad for these guys, because its one thing to lose a game like Manhunt 2. But to lose one of the best WRPGs of the year (maybe the only good one actually) really blows.
