GAMERS will be able to buy R18+ rated computer games in the ACT from January.

The ACT today became the first state or territory to pass laws to create an R18+ rating for computer games.

Federal parliament passed its laws in June to create the new ratings category.

The states and territories have to legislate as well to enforce the classifications.

Previously, the highest rating for computer games was MA15+, meaning overseas adult-only games were usually banned here or given a lower classification that allowed children to obtain them.

The new laws bring computer games in line with the classification system for films and other material, and make Australia more consistent with international standards.

ACT Attorney-General Simon Corbell said the new R18+ rating increased choice for adult gamers.

"By having a regulated and closely monitored R18+ industry for computer games, we can better protect those vulnerable members of our community by placing appropriate safeguards on the sale and distribution of adult-only gaming material,'' he said.

The R18+ classification will be introduced on January 1, 2013.
