"Not only are these policies supported by the evidence, they're also supported by everyday Queenslanders. The Foundation for Alcohol Research and Education shows over 80 per cent of Queenslanders support 3am closing for pubs, clubs and bars and over 60 per cent support a 1am lockout."

The previous government also intended to allow police to breathalyse patrons and ban patrons, but after inviting submissions from the public, decided against curfews and lockouts, in favour of increased policing, education and heavier penalties.

It was the issue which sent Anthony Lynham, a maxilfacial surgeon, into politics. Labor's intention to introduce measures influenced by what has become known as the Newcastle solution, saw him join the party and eventually win Stafford in a by-election.

But head of the Valley Liquor Accord Nick Braban, who campaigned against the need for lockouts, said the government's planned measures would have a negative impact on the economy and possibly exacerbate law and order issues surrounding entertainment zones.

"It is a reaction to a problem which will not go away if some venues close earlier," he said.
