The Federal Government has announced it will support a push for an adults-only classification for video games.

A decision on the matter is expected on Friday at a meeting of the Standing Committee of Attorneys-General.

A recent Galaxy survey has found strong support for an R18+ classification, with 80 per cent of people surveyed saying they believed an adult classification was needed, while a government public consultation on the matter received close to 60,000 responses - with 98 per cent in favour of an adult rating.

Currently in Australia, games classed above MA15+ are refused classification and cannot be brought into the country.

Home Affairs Minister Brendan O'Connor says an adults-only classification would include games with excessive violence or adult themes.

"We need a better classification system to protect our teenagers from accessing certain information, and we need a similar arrangement like film because both forms of entertainment are converging," he said.

"We want to provide guidance for parents and remove unsuitable material from children and teenagers."

The decision has been welcomed by online freedom advocates.

Colin Jacobs from online advocacy group Electronic Frontiers Australia says an R18+ rating would be a huge improvement.

"Right now games that are borderline at best are often pushed into the lower category so that they can be sold in this country," he said.
