Former Australian of the Year Rosie Batty is looking to make domestic violence an election issue by fronting a campaign to overhaul the family law system.
The "five-step" campaign, which is backed by 90 community groups, says the current system is failing victims and their children and recommends major changes to the Family Law Act.
Among the changes being sought by advocates is a ban on alleged domestic violence perpetrators cross-examining their victims in court and for courts to consider any family violence history when determining how to divide property in a divorce settlement.
They also want to change the way custody disputes are handled by removing references to "equal shared time" and "equal shared parental responsibility" from the Act, in favour of a greater focus on the safety of children.
The campaign also calls for specialised domestic violence training for judges and a mediation model with specialist lawyers and social workers.
Ms Batty, whose son Luke was murdered by his father two years ago, said the Family Court needed to be changed to "put kids first".
"There are clear steps that can be taken to deliver a safe path through the family law system, so our kids have a chance at a better life," she said.
Ms Batty also plans to present a petition to federal politicians on June 20, her son's 14th birthday, which is set to fall in the middle of the federal election campaign.
She appealed for members of the public to sign the Justice for Children petition.
"Now I am asking you to help me make sure that everyone knows about this plan, especially those who can make the changes needed for a better system," she said.
"Luke's 14th birthday is coming up on the 20th June. It's a really hard time but I'd love you to help me make it mean something particularly special this year."
A letter co-signed by the 90 organisations and sent to Prime Minister Malcolm Turnbull and Labor leader Bill Shorten accuses Family Court professionals of overlooking the impact of violence on women and their children.
"Now is an opportunity for all political parties to commit to putting the safety of women and children first in family law," the letter said.
"We are not asking for another review. We are not asking for another inquiry. We are asking all political leaders to act now, to put safety first in family law."
