Homicide rates are low by international standards. Violent offenders are primarily male, aged 18-30, blue collar. Most homicides and assaults are committed by persons known to the victim. Infants up to age 1 are of the greatest risk of homicide. Homicide risk varies inversely with occupational status.
Alcohol plays a major role in violence in Australia.
A considerable number of violent crimes never come to police attention. This includes the majority of sexual and domestic assaults.
