Queensland has finally joined the rest of Australia in officially approving an R18+ classification for video games.

The Classification of Computer Games and Images and Other Legislation Amendment Bill 2012 alters six current pieces of legislation, including the Classification of Computer Games and Images Act 1995.

For the bill to become law it must be signed by the governor of Queensland Ms Penelope Wensley, which is expected that to take at least another couple of weeks.

The bill allows games rated R18+ by the classification authority to be available for sale and rent in the state.

"The introduction of this classification should be welcome news for parents, who will now have more control over the games their children are playing," said Queensland Attorney General Jarrod Bleijie.

"I encourage parents to be guided by these classifications, as I’m sure many are unaware of the levels of violence and adult material contained in some computer games."

"This system has worked with films for a long time and it makes sense for computer games to be treated in the same way,” said Bleijie.

He added that a unified classification system would prevent restricted games from being brought in from other states and sold illegally in Queensland.
