One in three Australian women will experience physical violence. One woman is murdered every week by someone known to her.Family violence is a key driver of 23 per cent of national homelessness in Australia. It comprises 40 per cent of police time. It’s a factor in over 50 per cent of substantiated child protection cases. And it’s costing us. Violence against women costs the Australian economy $13.6 billion every year. That’s not so far, that’s every year.
