A Victorian woman whose former partner killed her 11-year-old son before being gunned down by police says she wants to become an advocate against domestic violence.
Luke Batty was beaten and stabbed to death in front of other children by his father Greg Anderson, 54, at a Tyabb cricket oval on the Mornington Peninsula last week.
Police then fatally shot the knife-wielding Mr Anderson, after failing to subdue him with capsicum spray.
Luke's funeral will be held at his former school, Flinders Community College, on Friday.
His mother, Rosie Batty, said she wants to campaign to end domestic violence.

"I really don't want to sound like some missionary ... (but) let's have a look at ourselves and our own faults," she told Fairfax Radio on Wednesday.
"Violence comes in many forms. Men and women are violent to each and we're violent to our children, we're violent to our animals."
Ms Batty said she has been flooded with messages of support in the past week.
"I really appreciate the comments that have been coming to me," she said.
Luke's funeral service will be at 11am (AEDT) on Friday.
Mourners have been asked to wear something yellow in his memory.
The service will be held in the school chapel for close family and friends but will be screened in the gym where other mourners are welcome to attend.
A private family cremation will follow the service.
The family has requested donations to an organisation for children affected by violence instead of flowers.
