South Australia is looking to restrict the sale of MA15+ titles to customers under the age of 18, the Attorney-General has said.
Speaking to GamespotAU, a spokesperson for John Rau said a new 18 and over classification is likely to be introduced to State Parliament in May, but that this could also directly affect the sale of games rated 15, effectively eliminating the difference between the two.
"Complementary South Australian legislation [on R18+ for games] is likely to be introduced in State Parliament in May," said the spokesperson.
"However, my long-stated position has been to protect children by creating a clearer distinction between games that may be suitable for children and those that are suitable only for adults."
"Therefore, my intention is that the South Australian legislation will prevent the sale of MA15+ games to minors. This move will give parents greater certainty about the appropriateness of games for their children."
The move, which will be policed at retail, would mean that customers under 18 would not legally be able buy titles such as Skyrim, Call of Duty: Modern Warfare 3 or Mass Effect 3.
The R18+ bill currently going through Australian parliament has been delayed by numerous inquiries into the matter, although it is hoped that the new classification will be turned in to legislation by January 2013.
