SO called "supergrass" laws to encourage people involved in organised crime to break the criminal code of silence have been passed by the South Australian parliament.
Attorney-General John Rau said the new laws follow a number of incidents where gang members, including bikies who had been attacked, had been unwilling to help police with investigations.
"The government does not accept that honour amongst thieves is reasonable behaviour," Mr Rau said.
Under the laws, offenders who co-operate with police and directly help combat serious and organised crime will be eligible to receive a significant reduction of their sentence if the court finds their co-operation is exceptional.
The court will still be required to balance out the gravity of their crimes against the help they provided.
"This is anything but a get-out-of-jail-free card as some of the uninformed have suggested," Mr Rau said.
