Minister for Home Affairs and Justice, Brendan O'Connor, has released a comparison of Australian and international games' ratings, which support the government's argument that Australian minors are being exposed to video game content which would otherwise be restricted to adults.

The comparison found that more than two-thirds of Australians rated MA15+ is restricted to adults only in comparative countries.

Some nine MA15+ game titles were given a 17+ or 18+ classification in all other countries while 15 MA15+ titles were given a 17+ or 18+ classification in the majority of other countries.

Blockbuster shooting title , which carries an MA15+ rating in Australia, is classified as an 18+ title in the UK and Europe. Crime title is similarly rated.

"Right now there are dozens of games that are classified as MA15+ in Australia, but in other countries these gaming titles are restricted to adults only," O'Connor said in a statement following the release of the comparison.
