Overview
The Australian Domestic and Family Violence Death Review Network (the Network) was established in 2011 to formalise and coordinate collaboration between death review mechanisms across Australia to share outcomes of reviews into deaths and homicides related to domestic violence where there is an identified history of abuse between the parties preceding the death. The Network has developed a National Minimum Dataset (NMDS) to identify key trends and patterns in intimate partner homicide with an identified history of domestic and family violence. Intimate partner homicides with no identifiable history of domestic and family violence are not included in the dataset. While most jurisdictions across Australia have formalised death review teams, the Australian Capital Territory is in the process of developing a formal death review process and Tasmania currently has no formal death review process. Several jurisdictions produce annual reports and case studies about domestic and family violence deaths which can be found on their websites.
Key data findings from the NMDS (reproduced from the Australian Domestic and Family Violence Death Review Network, & Australia’s National Research Organisation for Women’s Safety’s Australian Domestic and Family Violence Death Review Network Data Report: Intimate partner violence homicides 2010–2018 (2022) include:
Complete IPV homicide dataset (n=311)
•
Between 1 July 2010 and 30 June 2018, there were 311 IPV homicides across Australia.
•
More than three quarters of all cases involved a male IPV homicide offender killing a current or former female partner (n=240, 77.2%). The vast majority of those male offenders had been the primary user of domestic violence behaviours against the woman they killed (n=227, 94.6%).
•
Less than one quarter of all cases involved a female IPV homicide offender killing a current or former male partner (n=65, 20.9%). Even though the female partner was the homicide offender, in the majority of these cases she was also the primary domestic violence victim, who killed her male abuser (n=46, 70.8%).
•
In six cases, a male IPV homicide offender killed a male partner. Of these, three homicide offenders were the primary abuser against the partner they killed; two offenders were the primary victim of abuse; and in one case both parties mutually used domestic violence against each other.
•
There were no cases identified in this dataset where a female IPV homicide offender killed a female partner.
•
IPV homicide occurs across a broad age range. There was an age range of 18 to 82 years for male offenders and 18 to 75 years for female homicide offenders. Homicide victims’ ages ranged from 16 to 78 years for female victims and from 18 to 76 years old for male homicide victims.
•
The duration of relationship between homicide offenders and victims in this dataset ranged from less than a year to 45 years. This demonstrates that IPV homicides can occur at any stage during a relationship.
•
The majority of IPV homicide offenders (n=183, 60%) engaged in problematic drug and/or alcohol use. Importantly, this finding does not purport to identify problematic substance use as a causative factor for IPV homicide, but rather represents a pattern of behaviour and identifies possible sites of intervention.
•
Only approximately one third of all IPV homicide offenders and victims were engaged in paid employment at the time of the homicide (n=225 of 622, 36.2%). This is significant because workplaces can offer an additional site of intervention for domestic and family violence.
•
The data demonstrates an overrepresentation of Aboriginal and Torres Strait Islander people as both IPV homicide victims and offenders. While acknowledging these high rates, it is important to recognise that domestic and family violence is not a part of Aboriginal and Torres Strait Islander cultures, and there is a complex range of interrelated factors associated with the disproportionate incidence and severity of family violence in Aboriginal and Torres Strait Islander communities (discussed in the report below).
Male IPV homicide offenders who killed a female intimate partner (n=240)
•
Most male IPV homicide offenders killed a current female partner (n=154, 64.2%). Fewer killed a former female partner (n=86, 35.8%).
•
The majority of male IPV homicide offenders killed their current or former female partner in her home (n=151, 62.9%). In 97 of these cases (64.2%) this was a home the woman shared with the offender and in 54 cases (35.8%) this was the home the woman lived in but did not share with the offender.
•
The most common criminal justice outcome for male IPV homicide offenders who killed a female victim was a murder conviction (n=121, 63.0%). Forty-four male homicide offenders suicided after the homicide (18.3%) and in the majority of these cases, they suicided within 24 hours of the homicide (n=32, 72.7% of male offenders who suicided).
Female IPV offenders who killed a male intimate partner (n=65)
•
Most female IPV homicide offenders killed a current male partner (n=50, 76.9%). Fewer killed a former male partner (n=15, 23.1%).
•
Over two fifths of female IPV homicide offenders killed their partner in their shared residence (n=28, 43.1%). In nine cases the homicide occurred in the male partner’s home and in a further nine cases the homicide occurred in the female homicide offender’s home (13.8% respectively).
•
The most common criminal justice outcome for female IPV homicide offenders was a manslaughter conviction (n=40, 62.5%). One female IPV homicide offender suicided after the homicide.
IPV homicide and children
•
There were four cases in which children were killed together with their mother, resulting in the deaths of eight children.
•
Of the 311 IPV homicides examined in this dataset, there were at least 172 children under the age of 18 who survived the homicide involving one, or both, of their parents.
Focused IPV homicide dataset (n=292)
Domestic violence death review teams are uniquely positioned to conduct in-depth analysis and reviews so as to identify discrete characteristics present within a relationship prior to an IPV homicide. Drawing on data from those jurisdictions with a formalised death review mechanism in place, this report presents focused data findings around IPV homicide characteristics relating to separation or intention to separate, family law proceedings, domestic violence orders, and the nature of domestic violence and abusive behaviours used by the abuser prior to the homicide.
This focused subset of cases includes 224 cases where a male IPV homicide offender killed a female victim; 62 cases where a female IPV homicide offender killed a male partner; and six cases where a male IPV homicide offender killed a male partner.
Separation as a characteristic of IPV homicide
Male IPV homicide offenders who killed a female partner (n=224)
•
In about a third of the cases where a male IPV homicide offender killed a female victim (n=77, 34.4%) the relationship had ended prior to the homicide. In more than half of these cases, the relationship had ended within three months of the fatal episode of violence (n=44, 57.1% of separated couples).
•
Of the 147 cases where the relationship was ongoing, one or both parties had expressed an intention to separate in 53 cases (36.1%). The overwhelming majority of these cases involved the female homicide victim indicating an intention to separate from the male offender who killed her (n=50, 94.3%).
•
Accordingly, actual or intended separation was a feature in more than half of the cases where a male IPV homicide offender killed a female partner (n=130, 58.0%).
Female IPV homicide offenders who killed a male partner (n=62)
•
In just under a quarter of cases where a female IPV homicide offender killed a male partner the relationship had ended prior to the homicide (n=14, 22.6%). Five of these separations occurred less than three months prior to the homicide (35.7% of separated relationships).
•
Of the 48 cases where the relationship was ongoing, one or both parties had indicated an intention to leave the relationship in 14 cases (29.2%). In the majority of these 14 cases, it was the female homicide offender who had indicated an intention to separate from the male partner she then killed (n=8, 57.1%).
•
Accordingly, actual or intended separation was a feature in just under half of the cases where a female IPV homicide offender killed a male intimate partner (n=28, 45.2%).
Domestic violence orders
Male IPV homicide offenders who killed a female partner (n=224)
•
Current or historical domestic violence orders were evident in 96 cases where a male IPV homicide offender killed a female partner (42.9%). Accordingly, in 128 cases there was no evidence of a current or historical domestic violence order (57.1%).
•
In 49 cases, a current domestic violence order was in place between the male IPV offender and female victim at the time of the homicide (21.9%). The vast majority of these orders named the female homicide victim as the person in need of protection from the male homicide offender (n=44, 89.8% of cases with a current order). In two cases (4.1%) there were cross-orders in place at the time of the homicide where both the male IPV homicide offender and the female victim were named as needing protection from the other. In three cases (6.1%) the male IPV homicide offender was named as the person in need of protection from the female partner they killed.
•
Historical domestic violence orders between the male homicide offender and female victim were a feature in 67 cases (29.9%). In 53 of these cases, the female homicide victim was named as the protected person from the male offender (79.1%) and in 11 cases both parties were named as needing protection from the other (16.4%).
Female IPV homicide offenders who killed a male partner (n=62)
•
Current or historical domestic violence orders were evident in 41 cases where a female homicide offender killed a male partner (66.1% of female-perpetrated IPV homicides).
•
In 21 cases, a current domestic violence order was in place between the female homicide offender and the male homicide victim at the time of the homicide (33.9%). Twelve of these orders named the female homicide offender as the person in need of protection from the male homicide victim (57.1% of current orders); eight named the male homicide victim as the person in need of protection from the female homicide offender (38.1%); and one was a cross-order naming both parties as needing protection from each other (4.8%).
•
Historical domestic violence orders between the female homicide offender and male homicide victim were a feature in 29 cases (46.8%). In 17 of these cases, the female homicide offender was named as the protected person from the male homicide victim (58.6%) and in 11 cases both parties were named as in need of protection from each other (37.9%).
Domestic violence abusive behaviours
•
In the focused dataset (n=292), the vast majority of the 224 male IPV homicide offenders who killed a female victim were identified as the primary domestic violence abuser in the relationship (n=212, 94.6%). Of the 62 cases where a female IPV homicide offender killed a male partner, only a small proportion of women were identified as the primary abuser against the male partner they killed (n=5, 8.1%). In half of the six cases where a male IPV homicide offender killed a male partner, the homicide offender was identified as the primary abuser in the relationship (n=3, 50%).
•
Of the 212 cases in which a male primary domestic violence abuser killed a female victim, the majority used emotional and psychological abuse (n=173, 81.6%) and physical abuse (n=169, 79.7%) against the female partner they killed. Over half had been socially abusive (n=134, 63.2%), just over a quarter were financially abusive (n=58, 27.4%) and far fewer were known to be sexually abusive (n=34, 16.0%).
•
Stalking occurred in two fifths of the 212 cases in which a male primary domestic violence abuser killed a female victim (n=88, 41.5%). In 71 cases, the domestic violence abuser stalked the victim during the relationship (33.5%) and in 44 cases the abuser stalked the victim after the relationship ended (20.8%).
