The National Homicide Monitoring Program (NHMP) is Australia’s only national data collection on homicide incidents, victims and offenders. This report describes the 196 homicide incidents recorded by Australian state and territory police (except Australian Capital Territory) between 1 July 2017 and 30 June 2018. During this 12-month period there were 202 victims of homicide and 213 identified offenders. All but two incidents involved a single victim and offender and three-quarters of homicide victims knew the offender. The intimate partner homicide rate for women was 0.33 per 100,000, the lowest rate recorded since the commencement of the NHMP in 1989–90.
