What is this right?
Part IC of the Crimes Act 1914 (Cth) — sections 23F through 23S — sets out your rights when police question you about a Commonwealth offence. Before any questioning, the investigating official must give you the caution: you don't have to say anything, but anything you do say may be used in evidence.
The right to silence is a common-law right recognised at the highest level — Petty v The Queen (1991) is the case. You cannot be penalised for refusing to answer questions, and silence generally cannot be used against you in court.
Police interviews for Commonwealth offences must be electronically recorded where practicable under s. 23V. If the interview wasn't recorded, the prosecution has to explain why, and the court may refuse to admit the evidence. The recording rule was designed precisely to stop disputes about what was actually said.
One narrow exception: you must give your name and address in defined circumstances — for instance, under customs and border legislation or specific regulatory offences.
When does it apply?
These rights apply whenever AFP officers or other Commonwealth investigators question you about a suspected federal offence.
- The caution must be given whether you are under arrest or simply being questioned in circumstances where you are not free to leave.
- It applies to all people in Australia, including non-citizens.
- Special protections apply to Aboriginal and Torres Strait Islander persons (s 23H), who are entitled to communicate with a legal aid organisation and have an interview friend present.
What to Do If Australian Federal Police Are Questioning You About a Crime
- Listen to the caution carefully — make sure police have given it before questioning starts.
- Say: "I exercise my right to silence and wish to speak to a lawyer."
- Confirm that the interview is being recorded — ask if it is not.
- You may provide your name and address if lawfully required, but you do not need to answer further questions.
- Stay calm and repeat your request for a lawyer if police continue to ask questions.
What should you NOT do?
- Don't feel pressured to fill silences — police may use long pauses to encourage you to talk.
- Don't lie to federal police — providing false or misleading information to a Commonwealth officer is an offence under s 137.1 of the Criminal Code Act 1995.
- Don't agree to an "off the record" chat — there is no such thing in a police investigation.
- Don't answer "just a few questions" without legal advice, even if police say it will help your situation.
How South Australia differs from federal law
In South Australia, you have a right to silence during police questioning. You are generally not required to answer questions beyond providing your name and address when asked by a police officer who reasonably suspects you of an offence.
- Under section 74D of the Summary Offences Act 1953 (SA), police must caution you that you do not have to answer questions but that anything you do say may be used in evidence.
- South Australia does not have a provision allowing courts to draw adverse inferences from silence during police questioning — exercising your right to silence cannot be used against you at trial.
- Police interviews in SA for indictable offences should be electronically recorded (audio or video). Unrecorded admissions are subject to scrutiny under the Evidence Act 1929 (SA), section 34CA, which requires corroboration of unrecorded confessions.
- The investigation period for detained persons in SA is governed by section 78 of the Summary Offences Act, which allows detention for a reasonable time (generally interpreted as around 4 hours but not strictly defined, unlike some other states).
Additional Steps in South Australia
If questioned, clearly state: "I wish to exercise my right to silence and I want to speak to a lawyer." Contact the Legal Services Commission of SA (1300 366 424). If police exceed a reasonable investigation period, raise this with your lawyer immediately.
