As a customer entering a shop, you have rights when it comes to bag checking. They are:
You have the right to know before entry that a shop conducts bag checks.
Signage must be clearly displayed at the entrance/s to the shop.
Store personnel are only allowed to look in your bag; they are not allowed to touch the contents of your bag. However, if you are asked to remove an object in your bag so they can see inside properly you are expected to cooperate.
Personal handbags the size of a sheet of A4 paper or smaller should not be checked, unless the shopkeeper is certain the handbag contains goods from that shop which have not been paid for.
A shopkeeper is only allowed to detain you and call the police in situations where they are sure an offence has been committed.
If shop staff forcibly detain or search you and you have not committed an offence, you are entitled to make a complaint to the police, the store management or Privacy NSW.
