The total number of homicides, which includes both murder and manslaughter, has dropped for the past two years with 58 in 2016 and 48 last year according to provisional data.
Detective Superintendent Tim Anderson, national manager of criminal investigations said although the number of homicides was declining, it didn't change the fact that every one of those numbers represented a grieving family.
"Victims are at the heart of everything Police does and we are committed to bringing a sense of closure to their families by holding those responsible to account.
"It is this commitment and dedication which saw police resolve more than 96 per cent of homicide cases," he said.
The number of people killed by a current or ex-partner was also dropping - between 2007 and 2011 there were 63 compared to 52 between 2012 and 2016.
"We know that family harm is a serious issue that affects people of all ages and across all parts of society," Anderson said.
"Disturbingly, children under the age of 5 made up 12 per cent of homicide victims."
