Sydney - Last year's nudist weekend at the Elephant Rock Naturist Retreat near Brisbane was such a success that an even bigger clothes-less festival is planned for later this month at an Australian Pacific coast resort.

As many as 3 000 naked visitors, from Australia and from abroad, are expected at a weekend of live bands, body painters, performing artists, dancers and general fun and games in the beach town of Cabarita in far northern New South Wales.

Troublemakers will be kept out of Raw at Cabarita by security guards who will blend in with the crowd by also being nude.

"We call them undercover uncovered security," festival organiser Raice Nicholls said. "You don't know they're security, they're just acting like they are in the crowd, and they'll be keeping an eye on things."

The guards will stop anyone taking photographs and dissuade people from what Nicholls called "hanky panky". - Sapa-dpa
