Australian of the Year Rosie Batty will lead six speakers who will address a special joint sitting of Victoria's parliament on family violence.
Chief Commissioner Graham Ashton and Safe Steps family violence response centre chief executive Annette Gillespie will also speak to MPs.
The sitting is part of the Victoria Against Violence campaign, which includes 16 days of events to raise awareness of family violence.
Family Violence Minister Fiona Richardson said Ms Batty's address would be a historic moment.
"All MPs will get to hear her story and what she believes needs to be done to end the harm of family violence," she told reporters on Wednesday.
Marking White Ribbon Day on Wednesday, Ms Batty said the fight against domestic violence was only beginning but it was now on the same path as smoking, seen as a health hazard ignored for too long.
"I see this as a year where we have brought it out from behind closed doors into the daylight," she said.
Her son Luke was murdered by his father at a suburban Melbourne cricket oval in early 2014.
