Remaining Silent When You've Been Arrested
All Australian states give people the right to refuse to answer most questions from the police. You do need to provide your name, address, and birthdate; those are required. If you refuse to identify yourself, then you'll need to provide fingerprints. However, past that, you can instead say that you want to speak to a lawyer first and that you refuse to answer questions. It is too easy for police or people around you (including other people in jail, if that's where you end up) to misinterpret your statements as admissions of guilt.
