The laws will also hand the courts the power to ban patrons caught fighting near a pub or club from any licensed venue in Canberra.

Attorney-General Gordon Ramsay secured cross-party support in the Assembly on Tuesday for a range of new measures designed to crackdown on organised crime groups and public disorder.

The opposition backed the bill, but not before shadow-attorney general Jeremy Hanson again attacked the government over its refusal to introduce anti-consorting laws in the ACT.

Mr Ramsay said the laws would support the government's attempts to "target, disrupt and prosecute criminal gangs".

The maximum penalty for a range of crimes - including manslaughter, assault and threat to kill - would increase by 10 per cent if the offender was found to be linked to a criminal group.

Tougher sanctions will also be imposed on people charged with affray or fighting in public. A maximum 10 years' imprisonment will hang over someone who, as part of a group of five or more, attacks or threatens to attack another person.

"The key purpose of these amendments is to acknowledge and respond to the increased danger, fear and panic caused to the public by more serious incidents of violence, involving multiple people acting in common," Mr Ramsay on Tuesday.

Under the laws, a patron caught fighting "in the vicinity" of a bar or club could be banned from every licenced venue in Canberra for up to 12 months.

The chief police officer would apply to the courts to impose the so-called "exclusion order".

The government also wants to prevent construction companies or licensed venues from being used as fronts for criminal operations.

The new laws include provisions to strip an individual of their construction trade licence or liquor licence if they are engaged in criminal activity.

Mr Ramsay stressed that the new measure wouldn't capture any licence holder who had committed an offence in the past.

"Rather, there must be a causal connection between the person's criminal activity and the unacceptable risk that their continuing to hold the licence presents to community safety," he said.

Mr Hanson supported the legislation, but said the "patchwork" response wouldn't be necessary if the government bowed the opposition's demands and introduced anti-consorting laws.

Anti-consorting laws make it an offence to associate with a known criminal. They have been criticised for violating human rights, including freedom of association and expression.

"The bottom line is, in my view, the government's refusal to match other states in anti-consorting laws has resulted in a patchwork of laws being introduced to address the issues that we have with criminal activity in this town ... that seem unabated and ongoing," Mr Hanson said.

Mr Ramsay rejected the opposition's approach, saying the government was focused on laws which were "effective" in tackling serious and organised crime.

"The evidence is clear. Anti-consorting legislation ... that has been espoused by the Canberra Liberals are simply not effective in achieving their aims," he said.
