On 1 July 2016, stage 1 of the Tackling Alcohol-Fuelled Violence (TAFV) policy was introduced in Queensland, Australia and included restricted alcohol service to 03:00 in dedicated entertainment precincts (safe night precincts or SNPs). During stage 2 (from 1 February 2017), the number of extended trading permits (i.e. trading until 05:00) per venue were reduced; and during stage 3 (from 1 July 2017), networked identification scanners were mandated for late-night venues. We aim to examine whether patron drinking behaviours in two key SNPs changed significantly following stages 2 and 3.
