I actually thought this might happen (thanks to our no R18+ video game law):

"The highly anticipated video game Mortal Kombat, published by Warner Bros. Interactive Entertainment (WBIE) in Australia, has been refused classification by the Australian Classification Board and will not release in Australia. We are extremely disappointed that Mortal Kombat, one of the world's oldest and most successful video games franchises, will not be available to mature Australian gamers."
"WBIE would not market mature content where it is not appropriate for the audience. We understand that not all content is for every audience, but there is an audience for mature gaming content and it would make more sense to have the R18+ classification in Australia.
Violent games don't really interest me at all I couldn't care less when I found out Manhunt was banned in Australia; and Aliens vs. Predators had all its graphically violent content cut from the game for it's aussie release. But this new Mortal Komabat was something I would have liked to check out...
