The ACT Government hopes a proposal to introduce an R18+ rating for video games will gain traction at a national meeting of attorneys-general today.

Under the current guidelines, games that do not meet the MA15+ rating are refused classification.

The Federal Government is considering introducing an R rating as part of changes to the classification scheme, which would allow the sale of more violent and sexually explicit material to people aged 18 and over.

"The rating will bring computer games into line with film and literature in Australia and will give guidance to parents and young people about the suitability or otherwise of the material ," Mr Corbell said.

"It will also help address the black market that exists in the R18+ material."

State and territory attorneys-general are meeting in Adelaide today to discuss the move.

The Commonwealth, states and territories all need to agree to an R18+ classification for it to become a reality.

Mr Corbell says a number of jurisdictions have already backed the plan, but some states are yet to declare their hand.

He says if the national push fails, he will still work on introducing the classification in the ACT.

"But that's not a desirable outcome, a sensible outcome is to get a uniform scheme covering all Australians and that's what the ACT will be supporting," he said.

"We have been consistent for many years now in our support for an R18+ classification for computer games and I hope that result is achieved at the meeting.

"We rely on Commonwealth legislation in relation to these matters, so I'll be pursuing the matter further with my counterpart Brendan O'Connor if that is the path we have to pursue."
