Other states will support Queensland's contentious anti-bikie laws during a legal challenge in the High Court on Wednesday.
The United Motorcycle Council is challenging the Newman government's Vicious Lawless Association Disestablishment (VLAD) legislation and related laws on behalf of 17 gangs.
The laws were introduced last October after a vicious gang brawl on the Gold Coast.
They prohibit three or more bikies gathering in public and impose lengthy prison sentences on gang members convicted of crimes, among other measures.
Opponents argue they are constitutionally invalid and breach notions of equal justice.
Other states interested in introducing similar legislation will speak in support of the laws during Wednesday's hearing.
