The Department of Social Services in Canberra has released a 2016 report by KPMG that estimates the national cost of violence against women and children as $22 bn each year.
KPMG also believes that a further $4 bn in costs may be incurred for vulnerable groups such as Aboriginal and Torres Strait Islander women, but it does not yet have adequate data for such groups to be confident of the figure. This is a significant increase from a 2009 KPMG report, which estimated $13.6 bn.
KPMG says that part of the increase is due to widening the definition of emotional abuse and stalking as forms of violence, in line with changes by the Australian Bureau of Statistics.
The definition of violence used includes both domestic and non domestic violence, such as street and workplace violence. Violence Free Families estimates from the KPMG reports that the probable cost of family and domestic violence was about $16.5 bn pa in 2016, up from its previous estimate of $9.3 bn.
KPMG has also prepared a more detailed report for the Victorian Government that can be accessed here.
