"It's time for a combined approach and a triggering of common sense within government," Mr Close said.

Mr Close, who is director of Goori House in Cleveland and also runs an alcohol and drug referral centre in Fortitude Valley, has warned that calls for trading hours bans would not solve the problems and a united approach was the only way forward.

"We would love to meet with the Police Union and the liquor or hotel and club industry to discuss a joint approach that brings law enforcement, simple approaches such as trading hours limitations together with our approach to bring the rehab floor to the streets," Mr Close said.

"It's an approach that will provide trained alcohol and drug professionals working side by side with the frontline to identify and defuse situations, on the streets and in the clubs and the pubs.

"I'm worried that we will now see a knee-jerk reaction that will fail to address the problems and both the police and the community will again lose this battle."

Mr Close said trading hours bans, internationally, had not provided a solution.

"It's one that will do some good. It appeals to politicians because it costs them no money and grabs headlines but fails to address the real problems. It is one, however, that will create a whole range of new problems."

"We have to be careful we don't just move the problem.

"A change to trading hours pushes the problem back to the suburbs, back to home, and street violence becomes domestic violence. Police resources are then spread more thinly, as the problems spread geographically."

Mr Close said he advocated a combined approach that would bring trained alcohol and drug workers together with police and hotel bouncers.
