Gambling on computer and video gaming competitions will be banned in South Australia, following an attempt to legalise such a move, the State Government says.

Governments across the nation have been approached to legitimise betting on so-called eSports - events which typically attract dozens of gamers at tournaments across the world.

So far the Northern Territory is the only jurisdiction which allows such gambling to take place.

Consumer and Business Affairs Minister John Rau said he advised the Independent Gambling Authority to reject betting on computer gaming sporting events.

The announcement comes as Adelaide prepares to host the nation's largest Mario Kart competition at the Adelaide Arena today.

"Children are particularly vulnerable to the attraction of gambling on sporting contests conducted on the platform of video games," Mr Rau said.

"The Government is determined to keep our children cyber-safe.

"We do not want them to be introduced to gambling under the guise of a game."

The Government said there was little research available on the potential dangers of this form of gambling.

But it said it would continue to encourage the use of educational games as opposed to those that promoted betting.
