Do Police Need Evidence to Charge You in Australia?

You have been contacted by police, or you have been told a charge is coming, and you are sure of one thing: they have no real proof. Maybe it is one person’s word against yours. Maybe it is a handful of text messages. You might think police need to catch you red-handed, or need a confession. That is not how it works.

The short answer is that police do not need hard proof to charge you. They need a reasonable suspicion that you committed the offence, and that is a far lower bar than proof. The power to arrest on that basis sits in the Law Enforcement (Powers and Responsibilities) Act 2002 (NSW), s 99.

This page explains what actually counts as evidence, how much of it police need, and what happens next, so you know how serious this is and what to do now. The information is relevant to New South Wales laws.

The quick version

Here is the whole thing in ten seconds. Read the rest for the detail.

Being arrested is not the same as being charged

People use these two words as if they mean one thing. They do not, and the difference matters for you.

Being arrested means police are holding you, usually while they investigate or process a charge. Being charged means they have formally accused you of an offence. Police can do one without the other. They can hold you and release you without charge, and they can charge you without ever arresting you, by issuing a Court Attendance Notice instead. The power to arrest without a warrant, where an officer suspects on reasonable grounds that you have committed an offence, comes from LEPRA s 99.

Can police charge you without hard evidence?

Yes. This is where a lot of people get caught out.

You do not need to be caught in the act, and there does not need to be a confession, a witness, or CCTV. Police act on a reasonable suspicion that you committed the offence. That means they need reasonable grounds to suspect you were involved, not a case that would win at trial. The proof comes later, and it is the prosecution’s job to build it, not something that has to exist in full on day one.

So when you say “they have no evidence”, what you often mean is “they have no strong evidence yet”. That is a different thing, and it does not stop a charge.

What physical evidence can be used against you?

Physical, or hard, evidence is the tangible material police can point to. It usually includes:

• Photographs and video, including CCTV
• Forensic material, such as fingerprints or DNA
• Documents and records
• Physical objects connected to the alleged offence

If it exists, it strengthens the case. But as the section above says, none of it has to be in hand before you are charged.

What soft evidence can police rely on?

This is the part most people underestimate. Soft evidence is the material that is not a physical object: witness accounts, one person’s version of events, text messages, social media messages, and a pattern of repeated unwanted contact. On its own, any of it can be enough for police to act.

That last point catches people out constantly, especially where there has been contact after someone asked for it to stop:

And I hear people say it all the time: they were just trying to be calm, they just wanted to explain themselves. Cool. But if the other person feels harassed, if they feel intimidated or scared, especially after asking for you to stop, that can be enough for grounds for an AVO. In the mind of a judge, they would say that you were told to stop and you continued to persist.

The takeaway is simple. You do not need to have done something dramatic for soft evidence to carry weight. How the other person experienced it, and whether you kept going after being asked to stop, can matter as much as anything physical.

A real outcome

Let me tell you about a client we acted for, because it makes the point better than any rule can.

I had a client once who was shocked. He said he never touched the person, and they were right, they didn’t, but the court still granted the AVO based entirely on the threatening text messages.

He was certain he was safe because there had been no physical contact. It made no difference. The messages alone were enough for the court to make the order.

That was an AVO, a protective order, not a criminal conviction, so it is a different process. But it shows the same thing this whole page is about: how little it can take for police or a court to act on soft evidence alone.

How much evidence is needed to charge someone in Australia?

Less than you would think to charge you. Far more to convict you.

To charge, police need that reasonable suspicion. To convict, the prosecution has to prove the case beyond reasonable doubt, which is the highest standard in law. That gap between the two is the single most important thing to understand about your situation.

Here is the piece most people miss: a charge is not automatic even when there is evidence. For more serious matters run by the Director of Public Prosecutions, whether a matter proceeds is a two-limb decision. First, are there reasonable prospects of securing a conviction. Second, is a prosecution in the public interest. Both limbs have to be met (ODPP NSW Prosecution Guidelines). Many everyday charges, including a lot of summary and AVO-related matters, are prosecuted by police rather than the DPP, but the same basic logic applies: a weak case, or one that is not in the public interest to run, can be dropped.

How long can police hold evidence without charging you?

This is a fair question, and it comes up whenever police seize a phone, a laptop, or other property during an investigation. They can hold it while they investigate, and there are rules in New South Wales that govern how long they can detain you for questioning and when seized property has to be returned.

The exact detention period and the return-of-property provisions are worth confirming for your own situation before you rely on them.

How you are notified of a charge

There are three ways you find out you have been charged:

1. Arrest. Police take you into custody and charge you.
2. A Court Attendance Notice (CAN). In NSW this is the usual way you are formally charged without being arrested. It is a document telling you what you are charged with and when to be in court. It is issued under the Criminal Procedure Act 1986 (NSW).
3. A summons. A court order to attend on a set date.

However you are notified, the smartest move before you say anything is to get advice. What you say early can shape the whole matter, so it is worth reading what not to say in a police interview before you speak.

What happens after you are charged?

Two things happen quickly.

First, bail. Whether you are released, and on what conditions, is decided under the Bail Act 2013 (NSW). For serious or domestic violence offences you may be in a show-cause position, which means you have to show why you should be released rather than police having to justify holding you.

Second, if the charge is a domestic violence offence, police will usually apply for an interim AVO at the same time (Legal Aid NSW: charges and AVOs). So you can be dealing with a criminal charge and a protective order together.

From there, your first court date is the next step. A charge is not the end of the road. Depending on the matter, there are questions worth getting advice on early, including whether charges can be dropped. If there is an AVO in the mix, our AVO lawyers in Sydney can walk you through both sides of it.

Where this leaves you

If police have contacted you, or a charge is coming, do not talk yourself into thinking there is nothing to worry about because there is “no real proof”. The bar to charge you is low. The bar to convict you is high. The space between the two is where the real work happens, and it is where having someone in your corner early makes the most difference.
