Police in NSW have powers to stop, search and arrest people, but each power has legal limits. Knowing which power an officer is using can help you understand what you must do and when to ask for legal advice.
This guide explains everyday encounters with NSW Police under the Law Enforcement (Powers and Responsibilities) Act 2002 (NSW), often called LEPRA. It covers questioning, searches, arrest and practical steps if you are concerned about how police treated you.
At a glance: Ask why you have been stopped and whether you are free to leave. You can ask for legal advice before answering questions about an allegation. If you do not agree to a search, say so calmly, but do not physically resist.
Do you have to answer police questions?
You generally have a right to silence when police are investigating an allegation against you. That does not remove specific legal duties to identify yourself or provide information in certain situations.
For example, drivers have identification obligations, and police can require information in some vehicle investigations.
Under section 11 of LEPRA, police can require a person whose identity is unknown to them to disclose their identity if they suspect on reasonable grounds that the person may be able to assist in the investigation of an alleged indictable offence because the person was at or near the place where the alleged offence occurred, whether before, when, or soon after it occurred.
Ask whether the request is compulsory and which power applies. Do not give false details, and seek advice before discussing the allegation or agreeing to an interview.
Special caution rules can affect how silence is treated in some serious cases. Our police questioning fact sheet explains those rules and preparing for an interview.
When can police arrest you?
An arrest without a warrant under section 99 of LEPRA requires both reasonable suspicion of an offence and satisfaction that arrest is reasonably necessary for a listed reason. Suspecting an offence does not, by itself, complete that test.
The listed reasons include preventing further offending or flight, establishing identity where necessary, preserving evidence and ensuring a person appears before a court. Other arrest powers exist, including powers connected with warrants and bail.
For an arrest under section 99, the officer must intend at the time to charge the person. Arrest merely to question someone is not lawful under that section, as the Judicial Commission explains.
If you are unsure of your position, ask: “Am I under arrest, or am I free to leave?” An invitation to attend an interview is different from arrest; get advice before agreeing to go.
Police may use force that is reasonably necessary when exercising lawful powers, including arrest, under sections 230 and 231. You can challenge the lawfulness of an arrest or the force used afterwards without physically resisting at the scene.

When can police search you without a warrant?
Police do not always need a warrant, but they need a lawful basis for the search. Under section 21, an officer can stop, detain and search you where they have reasonable grounds for a suspicion covered by that section.
Those grounds include suspicion that you possess anything stolen or otherwise unlawfully obtained, a prohibited plant or prohibited drug, or something used, or intended to be used, in or in connection with a relevant offence. In a public place, police may also rely on a suspicion that you are carrying a dangerous article that is being, or has been, used in connection with a relevant offence. Different provisions cover other situations, including dangerous implements, searches following arrest and searches under a warrant.
Reasonable suspicion needs a factual basis. The information available to the searching officer at the time matters; finding an item later does not explain what originally justified the search.
| Type of search | What to know |
|---|---|
| Search under section 21 | Police need reasonable suspicion of one of the circumstances in s 21, including possession of stolen or otherwise unlawfully obtained property, prohibited drugs or plants, items connected with a relevant offence, or a dangerous article in a public place. |
| Ordinary personal search | Section 30 permits actions such as patting outer clothing, examining belongings and requiring removal of specified outer items. |
| Strip search | Additional necessity requirements and privacy safeguards apply under sections 31–34. |
| Knife scanning | A separate authorised scanning power can apply without individual reasonable suspicion. |
The knife-scanning rules are explained in our NSW knife laws guide. Do not assume every search requires consent, or that every police request is compulsory.
What changes if police ask for your consent?
Giving permission to a search is different from complying with a search police say they are legally entitled to conduct. Section 34A allows a search with a person’s consent, but only if police seek that consent beforehand. Before conducting the search, the officer must also provide evidence that they are police, unless they are in uniform, and give their name and place of duty.
If you do not agree, you can say: “I do not consent to this search, but I will not resist.” Refusing consent does not prevent police using an independent lawful power, and physically obstructing police can create further problems.
Consent does not remove the statutory search safeguards. Under section 29, a general consent to a search is not consent to a strip search. A consensual search must also be for the purpose for which police obtained the person’s consent.
What safeguards apply to a strip search?
A strip search is not an automatic next step after an ordinary search. Section 31 requires reasonable grounds to suspect the strip search is necessary. Outside a police station or other place of detention, the seriousness and urgency of the circumstances must also make it necessary.
A strip search may require a person to remove some or all clothing, but only so far as necessary for the purpose of the search, and may include a visual examination of the person’s body and a search of their clothes. The label an officer gives the search does not decide which safeguards apply.
Sections 32 and 33 protect privacy and dignity. Police must conduct the search in the least invasive and most private and expeditious way that is reasonably practicable, and must not unnecessarily expose, observe or question the person, subject to the qualifications in those provisions.
Section 33 prohibits a strip search from involving a search of body cavities or an examination of the body by touch. Children under 10 cannot be strip searched, and additional support-person protections apply to children aged 10–17 and people with impaired intellectual functioning, with limited statutory exceptions.
See our strip-search laws fact sheet for the detailed requirements.
Can police search your car or phone?
Police may, without a warrant, stop, search and detain a vehicle, and search anything in it, where the conditions in section 36 of LEPRA are met. Those conditions include reasonable suspicion that the vehicle contains stolen or otherwise unlawfully obtained property, prohibited plants or drugs, or something used, or intended to be used, in or in connection with a relevant offence; or that the vehicle was used in connection with a relevant offence.
Searching a phone, seizing it and requiring access to its contents raise separate questions. Ask what authority police rely on and seek advice before responding to a demand to unlock a device. Some requests are not compulsory, while specific legal powers can allow access to a locked phone.
Our mobile-phone search guide explains the issues in more detail.
Your rights and what you can do now
A clear record of the encounter helps a lawyer assess whether police used their powers lawfully. Focus on your immediate safety, then preserve the details while they are fresh.
- Ask for the officer’s name, station and reason for the action. Section 202 requires police, where reasonably practicable, to provide evidence that they are police, give their name and place of duty, and explain the reason for exercising a covered power.
- Ask for legal advice before answering substantive questions about an allegation.
- Tell police about a medical condition, disability, communication need or need for an interpreter or support person.
- Write down the time, location, words used, search steps and witnesses’ contact details.
- Keep paperwork and original recordings. Seek medical attention and keep records if you were injured.
- If charged, keep track of your court date and any bail conditions while obtaining advice.
How could a lawyer help your case?
A lawyer can assess the legal basis for the police action, examine the evidence and explain your options. That may include seeking police records or body-worn video and checking whether the officer had the necessary grounds before acting.
In a criminal case, evidence obtained improperly, or in contravention of an Australian law, or in consequence of such an impropriety or contravention, may be challenged under section 138 of the Evidence Act 1995 (NSW). The evidence is not to be admitted unless the desirability of admitting it outweighs the undesirability of admitting evidence obtained in that way. The court must consider the relevant statutory factors.
A complaint and a civil damages claim are different processes. Depending on the circumstances, advice from our criminal defence lawyers or police claims lawyers may be appropriate.
Frequently asked questions
Can police search me if I have not been arrested?
Yes, if another lawful search power applies. An arrest is not a prerequisite to a section 21 search or an authorised knife scan.
Does an unlawful search mean my charge is dismissed?
No. The court must consider any application to exclude evidence and the remaining prosecution case. Get advice about the specific breach and evidence involved.
Can I complain even if police found nothing?
Yes. Finding nothing does not itself establish misconduct, but you can seek advice about the grounds for the search and how it was conducted. Our LECC complaints guide explains the complaints process.
