A study published in the international scientific journal Addiction reveals that assaults and brawls reduce with restriction on pub closing time.
The study, conducted at the University of Newcastle, shows the number of assaults in the Central Business District (CBD) fell from 33 per month before the restrictions were put in place, to 22 afterwards.
The team of researchers, led by Associate Professor Kypros Kypri, compared the Newcastle CBD assault rates with those in the nearby suburb of Hamilton, where late trading venues were not subject to the restriction. The study took into account long term trends in assault rates as well as certain reporting biases.
In 2008, due to the high rates of alcohol-related violence and social disorder occurring in Newcastle CBD, the NSW Liquor Administration Board (since abolished) imposed restrictions on 14 CBD venues. Pubs and clubs were required to close at 3.30am and to implement a 1.30am lockout to prevent more patrons from entering the venue.
Governments throughout Australia have so far resisted introducing earlier closing times. "One has to wonder what sort of reduction in harm would occur if licensed premises across Australia were to cease serving alcohol at 2am, as is required, for instance, everywhere in California, and how many serious injuries could be prevented," A/Professor Kypri said.
