Mortal Kombat has been refused classification in Australia, IGN AU reports. According to the site's sources, retail outlets have been asked to remove all promotional materials, as well as cancel preorders.

Warner Bros. Interactive Entertainment, the game's publisher, said in a statement that it's "extremely disappointed" that the title will not be available to "mature Australian gamers." Due to Australia's lack of an R18+ rating for games, all titles must fit the category of "MA 15+" or be refused classification, and thereby be banned from sale in the country.

We're currently following up with WBIE to find out if it's planning an appeal.
