Homicide is among the most serious of all crimes. Preventing homicide and other lethal violence remains a key priority for Australian criminal justice and law enforcement agencies. The National Homicide Monitoring Program (NHMP) and its collection of data is Australia’s only national system with the capacity to monitor homicide rates, facilitate detailed analysis of homicide types and trends and communicate this to key stakeholders including police, government and non-government organisations, and the general public.
The NHMP collects data on the following:
The NHMP draws on two key sources of data:
Where appropriate, the data are further supplemented by media reports, which are monitored daily by staff at the AIC.
The accuracy of NHMP data is ensured through a quality control process that involves crosschecking the information contained in police offence records with other data sources. These supplementary sources may include post-mortem coronial reports, information provided by other divisions of the police services (such as statistical services, homicide squads or major crime units and firearms registries) and media reports. Should there be any discrepancies between the information provided in the police offence report and one of the additional sources, the circumstances are verified with the police source. Depending on the reliability of the additional source, and the information provided in response to the NHMP query, the NHMP data relating to the homicide incident may be updated.
Existing NHMP data are updated on a biennial basis; hence historical data presented on this site may be different from data published in previous reports.
