The Australian Federal ratings body is the Office of Film and Literature Classification. Their mandate is not to act per se as a censorship body but rather to allow the Australian people to make informed decisions about media content prior to exposing themselves or their children to that content. Note that they can issue an X rating to film media even though X rated material is banned in the majority of Australian states and territories.
The appropriate Federal position should be to allow games to be classified R18+, and then leave individual states to decide what ratings can be sold. (The appropriate State position is to then allow R18+ games to be sold.)
With the recent change in the Australian Federal Government, a change to the classification system may now be in the works, albeit as a depressingly low government priority. However, a major opponent to any change is South Australian Attorney-General Michael Atkinson. In a recent speech in the SA Parliament, he said:
I have consistently opposed an R18+ classification for computer games. I am concerned about the harm of high-impact (particularly violent) computer games to children. [...] I do not want children to be able to get their hands on R18+ games easily. I understand that the lack of an R18+ classification denies some adults the chance to play some games, however, the need to keep potentially harmful material away from children is far more important.This is an inconsistent position for a number of reasons. Firstly, R18+ games would not be worse than R18+ movies. Yes, they are interactive, but the OFLC already takes interactivity into account when issuing a rating. Identical content is given a higher rating where it is interactive, so a M15+ film could received a R18+ rating in an identical but interactive context. This is despite the fact that there is no clear evidence showing any harmful effects on children from exposure to violent or mature gaming content, or evidence showing that interactivity increases the impact of media.
Secondly, he makes two assumptions: (1) that if R18+ games are in Australia, children will play them, and (2) that if they are not, less children will play them. Yes, children will play them, in the same way that children will watch R18+ movies and get access to porn. That's the magic of the internet. It's also the magic of informed parenting, where parents make their own decisions about how worrying they think these things are, and impose various levels of either enforcement or supervision to control and educate their children's access to content. People will see mature content if they want to see mature content; that's a given. With an appropriate classification system parents can be informed about this content and better understand what their children are being exposed to.
On this topic Mr Atkinson goes on to say:
Proponents for the classification say the latest technology allows gaming platforms and computers to be programmed to allow parental locks. Today’s children are far more technologically savvy than their parents. It’s laughable to suggest that they couldn’t find ways around parental locks if R18+ games were in the home.Of course dedicated kids could find their way around parental locks on games. But is Mr Atkinson really saying that kids getting access to their parents' R18+ games is a greater worry than them accessing their parents' pharmaceuticals, firearms or fireworks, all of which are legal in Australia, often without a licence?
The law is a blunt instrument. It should not be used to legislate responsible parenting. If Mr Atkinson is worried about the effects of high-impact games on minors then he should be the foremost supporter of a system that provides parents with high-quality information about game content, and encourages parents to share games with children and discuss their content openly and maturely.
