Rights During Police Questioning in Western Australia

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 Western Australia differs from federal law
WA maintains a strong right to silence during police questioning under the Criminal Investigation Act 2006 (WA).
- Under section 138(2) of the CIA, police must caution a person before questioning that they do not have to say anything but that anything they do say may be given in evidence. You are only required to provide your name and address (CIA, s 16).
- All police interviews for serious offences should be electronically recorded (audio and video) under the Criminal Investigation (Identifying People) Act 2002 (WA) and WA Police operational procedures. Unrecorded confessions may be challenged in court.
- The maximum detention period for questioning is generally 6 hours, which can be extended by a senior officer for up to a further 6 hours, or by a magistrate for a further period (CIA, s 141).
- WA has an additional requirement for persons of Aboriginal or Torres Strait Islander descent: police must take reasonable steps to ensure that a qualified interpreter is available and that a support person is present during questioning.
