Should we have R rated computer games in Australia?

The new federal government is considering amending the rules for video game classification.   Currently in Australia Video Games can be only given a classification as high as MA.  

There is opposition from the Australian Family Association and the Attourney General of South Australia who are opposed to a change.   South Australia's AG Michael Atkinson has attempted to explain his log held position in the state's parliment.   Meanwhile Ron Curry, head of the Australian Interactive Entertainment Association has suggested that the rest of the country should move forward without South Australia.

Meanwhile around Australia the games industry and sales continues to grow.

What do you think should happen?   Should R-rated games be available?
