As Mortal Kombat has been refused classification in Australia, it is considered objectionable material. It is therefore a prohibited good and illegal to import into Australia.

Customs and Border Protection works closely with Attorney General?s Department to identify imported games that are banned in Australia. This includes games purchased over the Internet from foreign websites. Attorney General?s Department regularly updates Customs and Border Protection about classification decisions on publications, films, and computer games, including the reclassification of material, and about different versions of computer games (some of which may be refused classification), and how to identify those versions at the border. This information is then used to assist in identifying and seizing banned versions of games.

Any copies of the games detected at the border, including via international mail, will be seized.
