Although the lockout laws have been blamed for killing Sydney’s night life, a new study claims the limited trading hours have a positive impact on reducing violence.

The new global study conducted from Melbourne’s La Trobe University, stated that increasing trading hours resulted in higher rates of harm whereas restricting trading hours reduces harm.

A paper published in the Sax Institute’s Public Health Research and Practice Journal recently, involved a review of 21 related studies, including 7 from Australia.

There have been calls for the NSW government to ease the 1:30am lockout laws but the study highlights the effectiveness of late trading restrictions to reducing late night violence in the country.
