Ten bikie gangs in South Australia have been declared criminal organisations with the state's new anti-gang laws coming into effect.
Attorney-General John Rau says there should be an immediate reduction in the activity of the groups concerned.
The gangs covered by the new laws are the Bandidos, Comancheros, Descendants, Finks, Gypsy Jokers, Hells Angels, Mongols, Nomads, Rebels and Red Devils.
