Family and domestic violence (FDV) is a significant social issue that causes major harm across Australia. Alcohol has been identified as a contributing factor to FDV, and as such increased understanding of the role of alcohol in police-reported FDV incidents may provide the basis for developing specific clinical and forensic approaches. This study...

Introduction and aims: Risk-based alcohol licensing (RBL) has been introduced in several jurisdictions in Australia, New Zealand and Canada with the intention of reducing harm in and around alcohol outlets. RBL involves tailoring licence fees or regulatory agency monitoring levels according to risk criteria such as trading hours, venue size and co...

Alcohol mixed with energy drinks (AmED) is an alcoholic beverage category that has emerged in the past decade. AmED are novel because they are typically consumed by high-risk alcohol consumers in contexts where elevated drinking is commonplace and where intoxication is regularly a desired outcome. AmED consumers positively self-identify as high-ris...

powers to exclude individuals from public areas form a key part of the policing of space and the control of undesirable behaviors. The rationale for police-imposed banning is framed around a presumed need to manage the risk of disorder, and assumes a combination of operational, deterrent and community safety effects. In Australia, the reach of bann...

Objective: We undertook a systematic review to assess the effects of extensions and restrictions in trading hours of on- and off-license alcohol outlets. We included new primary studies that help address limitations in previous reviews. Method: We systematically searched electronic databases and reference lists, up to December 2018, and contacte...
