Apparently, in WA, stalking is enough to get a restraining order.
What is a violence restraining order?
Violence Restraining orders are orders made under State laws that provide a quick and flexible method of obtaining legal protection from many forms of violence or unacceptable behaviour. Family and domestic violence includes emotional, physical, sexual and psychological abuse. If your partner, ex-partner or a family member hurts, threatens or humiliates you, it is family and domestic violence.
The law states that an act of family and domestic violence includes assaults, injuries, threats,
stalking, damaging property, hurting animals or pets, and acting in an ongoing intimidating, offensive or emotionally abusive manner.
Physical violence,
stalking and threats of violence are crimes.
