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 South Australia differs from federal law
In South Australia, police search powers are governed by the Summary Offences Act 1953 (SA) and specific legislation. Different types of searches have different legal thresholds.
- Personal searches: Police may search a person without a warrant if they reasonably suspect the person is carrying a weapon, stolen property, drugs, or evidence of an offence (Summary Offences Act, s 68).
- Vehicle searches: Police may search a vehicle without a warrant if they reasonably suspect it contains stolen property, drugs, or items connected to an offence.
- Premises searches: Generally require a search warrant issued by a magistrate or justice under the Summary Offences Act, Part 16. Police can enter premises without a warrant to prevent a breach of the peace, in fresh pursuit, or under the Controlled Substances Act 1984 (SA) for drug-related offences.
- For personal searches, police must provide their name and reason for the search. Strip searches may only be conducted by an officer of the same gender and out of public view.
- The Controlled Substances Act 1984 (SA) provides extensive search powers for drug-related offences, including the use of drug detection dogs.
Section 74A — mandatory disclosure of name, date of birth and address
Section 74A of the Summary Offences Act 1953 (SA) allows a police officer to require a person to state their name, date of birth and address if the officer reasonably suspects the person has committed, is committing, or is about to commit an offence, or may be able to assist in the investigation of an offence. The suspicion must be objectively reasonable; a bare assertion is insufficient.
Section 74A(3) makes refusal to comply, or giving a false name/DOB/address, an offence carrying a maximum penalty of a fine of $1,250 or imprisonment for 3 months. Note this obligation is more limited than at a driving stop, where the Road Traffic Act also requires production of a licence.
Section 81 — strip search in custody
Section 81 governs strip searches in police custody. The search must be conducted by an officer of the same gender as the person being searched, out of the view of anyone not reasonably needed to conduct the search, and recorded. It may only occur where there is a reasonable suspicion that the person is concealing an item relevant to the offence or that could be used to cause harm.
Section 82A — spit-hood ban
Section 82A prohibits the use of spit hoods (devices placed over the head of a detained person) in SA Police custody and in youth detention — one of the first statewide legislative bans in Australia. Breach is a disciplinary matter and potentially triggers civil liability.
Section 83A — right to an interpreter
Section 83A provides a statutory right to an interpreter for persons in custody who do not speak English sufficiently to understand questioning or to communicate their rights. Questioning must pause until an interpreter is available; statements obtained in breach are liable to exclusion under s.138 of the Commonwealth Evidence Act equivalent and the SA common-law fairness discretion.
Aboriginal Legal Rights Movement (ALRM) — custody notification
If the person in custody is Aboriginal or Torres Strait Islander, SAPOL is required to notify the Aboriginal Legal Rights Movement (ALRM) as soon as practicable under the established custody-notification protocol. ALRM provides urgent telephone legal advice and a field officer where appropriate. Failure to notify has been treated as a significant procedural breach affecting admissibility.
Additional Steps in South Australia
If you believe a search was unlawful, do not physically resist but clearly state you do not consent. Note the officer's name and station. Contact the Legal Services Commission of SA or lodge a complaint with the Office for Public Integrity (OPI).
