The Democrats' sole remaining parliamentarian, David Winderlich, said on Thursday he will seek amendments to the laws, which are being considered interstate following recent bikie violence.

The Rann government on May 14 declared the Finks motorcycle club a criminal organisation, meaning police can apply to courts for control orders banning members from associating or contacting other gang members.

Control orders have been placed on two Finks bikies this week in the first use of the laws.

But Mr Winderlich said the laws were a threat to people who innocently associated with the bikies.

"The bizarre decision to put a leading Fink under a control order but keep details of his crimes secret was the last straw for me," he said in a statement.

"It means the community has no way of assessing how these draconian laws are being used.

"This is a law that can send you to jail for chatting on Facebook or going fishing with your uncle.

"That's why I'm amending the laws to include close family like partners, cousins, uncles and aunts as lawful associations."
