What is this right?
Part IAA of the Crimes Act 1914 (Cth) sets out search and seizure powers for Commonwealth offences. The default rule is that police need a search warrant from a magistrate or judge before searching you, your property, or your belongings. The warrant has to specify what they're looking for and where.
To get a warrant, police must show the issuing officer there are reasonable grounds to suspect evidence of a Commonwealth offence will be found. The warrant must be executed within the stated period — usually 7 days.
The exceptions where police can search without a warrant: during a lawful arrest (s. 3ZE), in an emergency where evidence may be destroyed, or with your voluntary consent. The word that matters there is "voluntary" — pressure, even subtle pressure, can render the consent invalid.
If a search runs unlawfully, the evidence may be excluded under s. 138 of the Evidence Act 1995 (Cth). Australian courts use the discretion regularly when the breach is meaningful.
When does it apply?
These protections apply when AFP officers or other Commonwealth law enforcement want to search you or your property in connection with a federal offence.
- This covers searches of your home, vehicle, person, bags, and electronic devices.
- It applies to all people in Australia.
- Different rules may apply at airports and borders where customs officers have broader powers under the Customs Act 1901.
What to Do If Australian Federal Police Want to Search You or Your Property
- Ask: "Do you have a search warrant?"
- If they have a warrant, ask to read it and note what it authorises.
- Say clearly: "I do not consent to this search" — even if police proceed, stating this preserves your right to challenge the search later.
- Observe and note what police search and what they take — they must provide a receipt for seized items (s 3L).
- Contact a lawyer as soon as possible if you believe the search was unlawful.
What should you NOT do?
- Don't physically obstruct police carrying out a search — even if you believe it is unlawful, challenge it in court.
- Don't say "go ahead" or give casual consent — this may count as voluntary agreement.
- Don't destroy, hide, or tamper with evidence — this is a separate offence under the Criminal Code Act 1995.
- Don't unlock your phone or devices voluntarily without legal advice — speak to a lawyer first about your obligations.
How Western Australia differs from federal law
Search and seizure powers in WA are regulated by the Criminal Investigation Act 2006 (WA), which provides a comprehensive framework for police search powers.
- Police may search a person without a warrant if they reasonably suspect the person has something that is connected to an offence or that could endanger safety (CIA, s 68). A basic search does not require suspicion if the person has been arrested.
- For searches of premises, a warrant is generally required. Search warrants are issued by a justice of the peace or a magistrate under Part 5 of the CIA.
- Police must generally identify themselves and state the reason for the search before conducting it. Searches must be conducted with regard to the dignity of the person being searched.
- WA has specific powers for drug detection. Police can use drug detection dogs in certain circumstances without a warrant, including at licensed premises and major public events.
- The Misuse of Drugs Act 1981 (WA) provides additional search and seizure powers specific to drug offences.
