A Queensland gang expert says gang laws similar to what National is proposing have worked there.

National wants to ban gang patches in public and on social media as well as banning gang members from gathering.

Queensland University of Technology's Mark Lauchs told Tim Dower it'd be effective against Australian groups Comancheros and Rebels that have been setting up here.

But thinks it may be a different story for gangs like the Mongrel Mob.

He says the Mob has a different type of status like a family organisation and even having Government funding for community projects, there may be more difficulty.
