Police-issued barring notices in Western Australia: An analysis of the type, seriousness and trajectory of associated offences

Introduction: Police-issued barring notices are currently used in Western Australia in response to alcohol-related disorderly and anti-social behaviour. This paper examines the type, severity and trajectory of the offending behaviours associated with served barring notices.

Method: WA Police Force de-identified the data for 3815 individuals who had received one or more police-imposed barring notice/s between 2011 and 2020. The offence category associated with each barring notice was examined to explore the overall breakdown and whether/how offending categories change for recipients of subsequent barring notices.

Results: For single and multiple barring notice recipients, the most common offence categories were fighting/physical violence and public order offences. Within a subset of the data, non-anti-social offences also spiked. Aggressive behaviours predominate for recipients in metropolitan areas, compared with public order offences in regional locations.

Discussion and conclusions: For recipients of multiple barring notices, behaviours do not become more serious but neither do they moderate to any notable extent. The low number of repeat barring notices (5%) may suggest an overall beneficial effect on recipient behaviours but more analysis is needed to examine the potential confounding effects of factors, such as fly-in/fly-out workers, policing and locational differences.
