Incidence of assault in Sydney, Australia, throughout 5 years of alcohol trading hour restrictions: controlled before-and-after study.

The 2014 alcohol supply restrictions for pubs and bars in Kings Cross (KX) and the central business district (CBD) of Sydney, Australia were followed by a substantial reduction in the incidence of assault in KX and to a lesser extent in the CBD, possibly displacing some cases to adjacent areas and earlier in the evening.
