If an order is breached, the police have the power to arrest without a warrant if there are witnesses or evidence of the breach. Any person who is stalked is able to apply for an Intervention Order. Restraining Orders are similar to Intervention Orders but are only for married and divorced couples, or couples who have had children together. They are obtained from the Family or Magistrates Court. If breached, you have to go back to the court which issued the Order.
Police can arrest without a warrant if the Order is for personal protection.
Restraining Orders are for an indefinite time and enforceable Australia wide. Only you can apply for your Restraining Order and they are more difficult to obtain than Intervention Orders, involving complex paperwork which requires a lawyer. Penalties for breaching the Order are not as severe as for Intervention Orders. Leaving will not mean that you give up rights to property or financial support. Your partner will not determine your entitlements or who shall have custody of the children.
