What to do in the first 24 hours after arrest

The first 24 hours after an arrest in Australia are often the most critical period in any criminal matter. Knowing what to do, and what not to do, can protect your rights and your case.

Being arrested is frightening. Most people have no idea what their rights are in those first chaotic moments, and the decisions made in the hours immediately after arrest can have lasting consequences on the outcome of a criminal matter. Here is what you need to know if you or someone close to you has been taken into custody in Australia.

You have the right to remain silent. Use it.

This is not a cliché. It is the single most important thing to understand. In every Australian state and territory, you have the right to remain silent when questioned by police. You are required to give your name and address, and in some circumstances your date of birth, but you are not required to answer questions about what happened, where you were, or who you were with.

Police questioning in the hours after arrest is specifically designed to gather evidence. Anything you say will be recorded and can be used against you in court. Even a statement that feels innocent or explanatory can be taken out of context. Say nothing about the alleged offence. Tell the officer politely: "I'd like to speak with a lawyer before I answer any questions." Then stop talking.

This applies whether you believe you're innocent, whether you want to cooperate, or whether you think a quick explanation will resolve everything. It won't. The investigation is already underway. Your words are not going to stop it; they are only going to add to the evidence file.

Request a lawyer immediately

You have the right to contact a lawyer before being interviewed by police. Exercise that right as early as possible. Don't wait to see how things unfold. Don't assume the matter is minor enough to handle yourself. Ask for a lawyer by name if you have one, or ask police to contact Legal Aid for duty lawyer assistance if you don't.

Ann Valos Criminal Law provides urgent advice for people who have been arrested or are facing police questioning. Getting accredited specialist advice at this stage, before you've said anything to police, is the most protective step you can take. A criminal law specialist will advise you on whether to participate in an interview, what conditions apply to any caution, and what to expect next.

The duty to caution you exists in Australian law, but the caution is not a substitute for legal advice. Police must tell you that you don't have to say anything, but they don't have to tell you that speaking could seriously damage your position. That's what a lawyer is for.

What happens during police custody

After arrest, police can hold you for questioning for a limited period. In New South Wales, the general investigation period under the Law Enforcement (Powers and Responsibilities) Act 2002 is four hours, which can be extended in certain circumstances. Other states have comparable frameworks with their own time limits and extension rules.

During this period, you may be fingerprinted, photographed and asked to participate in a recorded interview. You're entitled to have a support person present in some circumstances, and you're entitled to access an interpreter if English isn't your first language. If you're under 18, police must notify a parent or guardian and a support person must be present during any questioning.

After the investigation period, police must either charge you, release you unconditionally, or release you on bail. If you're charged, a bail decision follows, either at the police station or before a magistrate. Understanding what happens at a bail hearing in Australia is worth reading before that moment arrives.

Five mistakes people make in the first 24 hours

The following errors come up consistently in criminal matters and can each cause real damage to a case:

  • Talking to police without legal advice. The most common and most costly mistake. See above.
  • Calling a friend or family member from the watch house phone without considering who might be listening. Calls from custody are routinely recorded. Don't discuss the alleged offence.
  • Posting anything on social media. Stop entirely. Screenshots of posts, check-ins, messages and comments have all been used as evidence in Australian criminal prosecutions.
  • Consenting to a search without understanding your rights. Police generally need a warrant or a specific lawful power to search your home or device. Consent removes that requirement. If police ask to search, ask your lawyer first.
  • Assuming the matter will go away. Even if police release you without charge initially, an investigation may continue. Don't assume silence means the matter is over.

After you're released: the next steps

If you're released on bail, read every condition carefully. Bail conditions are legally binding and breaching them is a separate criminal offence. Common conditions include reporting to a police station at set intervals, surrendering your passport, living at a nominated address, or having no contact with particular people. If a condition is unworkable, a lawyer can apply to vary it.

Get legal representation organised before your first court date. The court process that follows an arrest in Australia moves through several stages: a first mention, possible further mentions, committal proceedings in some cases, and then a hearing or trial. Understanding what happens after a criminal charge is laid in Australia gives you a clearer picture of what lies ahead.

Gather any evidence that might be relevant to your defence while it's still fresh: receipts, CCTV footage, text messages, witness contact details, anything that places you somewhere or documents what happened. Evidence can be lost or overwritten quickly. Your lawyer will tell you what's worth preserving once you've briefed them.

Why the first 24 hours matter so much

The evidence gathered in the immediate aftermath of an arrest often forms the backbone of the prosecution's case. Police interview records, admissions, physical evidence collected during searches, digital data pulled from phones: most of it is obtained in that first window. A person who speaks carefully, says nothing incriminating, and engages a lawyer early gives their defence the best possible starting point.
