“I Only Recorded it to Protect Myself” – When Secret Recordings Become Their Own Criminal Problem in NSW

A partner is yelling. A housemate is threatening. A boss is saying something outrageous. A family argument is spiralling. Someone presses record on their phone thinking, “I need proof.” Sometimes that instinct helps. Sometimes it creates an entirely new legal problem. In NSW, recording someone without consent can intersect with the Surveillance Devices Act 2007, domestic-violence allegations, stalking or intimidation, AVO disputes, and even separate offences for publishing or using the material improperly.

National Criminal Lawyers® already has a strong internal article on exactly this issue – “Is It a Crime to Record Someone Without Their Consent in NSW? What the Law Really Says” – and it is the perfect foundation for a more current, reader-focused piece like this one.

This topic is not just technically important. It is current and socially relevant too. Legal Aid NSW warned in June 2025 of rising tech-facilitated coercive control, saying almost 8,000 women had reached out to its Domestic Violence Unit in the previous financial year. AIHW says 1 in 5 women and more than 1 in 15 men have experienced stalking since age 15, and that half of the adult population has experienced some form of technology-facilitated abuse.

ANROWS’ national survey likewise found that one in two Australians had experienced technology-facilitated abuse in their lifetime, with about 36.7% of most-recent victimisation experiences occurring in a current or former intimate-partner relationship. That is exactly why recording law is no longer just an old privacy topic; it is now entangled with modern domestic abuse, surveillance and digital-control dynamics.

What is the actual offence?

The starting point is s 7 of the Surveillance Devices Act 2007 (NSW). The provision says a person must not knowingly install, use or maintain a listening device to overhear, record, monitor or listen to a private conversation to which they are not a party, or to record a private conversation to which they are a party, unless an exception applies. The maximum penalty is 100 penalty units or 5 years’ imprisonment, or both, for an individual. That maximum surprises many people, because the conduct often feels ordinary and domestic rather than “serious criminal”. But that is the statute.

That wording immediately answers one of the reader’s biggest misconceptions: in NSW, even being a party to the conversation does not automatically make recording safe. The law does not begin from “one-party consent”. It begins from prohibition, then looks to exceptions. That is exactly why these cases are so easy to get wrong.

The exception people rely on most – and misunderstand most

The main practical exception is in s 7(3)(b)(i): recording may be lawful if it is reasonably necessary for the protection of the lawful interests of the person making it. NCL’s own article explains this in a very reader-friendly way: for example, if someone records a conversation with a violent partner to protect themselves from threats, blackmail or abuse, the recording may fall within the lawful-interests exception. But the key words are “reasonably necessary” and “lawful interests” – not “useful”, not “nice to have”, and not “I wanted leverage”.

That distinction is where many people get into trouble. A recording made to protect yourself from threats may be arguable. A recording made to shame someone, gain advantage in a breakup, manipulate family proceedings, or blast material onto social media is much harder to defend. NCL’s article is especially strong on this point: even if the original recording is arguably lawful, sharing or using it improperly can trigger a whole new set of problems.

What counts as a “private conversation”?

This matters more than people expect.

Section 3 of the Act defines a private conversation broadly as a conversation carried on in circumstances that may reasonably be taken to indicate that any of the parties desire it to be listened to only by themselves or with consent-limited listeners. In plain English, that can include phone calls, home conversations, a discussion in a car, a workplace office conversation, or even a quieter exchange in a public place if it is obviously not meant to be broadcast. NCL’s recording article summarises the practical effect well: shouting in public is different; an argument in a kitchen, living room, office or parked car is much more likely to be treated as private.

This is exactly why you should be cautious about assuming you own home is a legal free zone. A home may feel private, but privacy cuts both ways. You are more likely to be in a “private conversation” there, not less.

The real reader question: “Can I record an argument with my partner to protect myself?”

Sometimes yes, sometimes no – and the difference is usually purpose, scope, and what you do with the file afterwards.

If you are personally involved in the argument and the recording is reasonably necessary to protect your lawful interests – for example, to capture threats, abuse or coercive conduct for police or court use – there may be a lawful-interests argument. Indeed, victims sometimes lawfully record threats for their own safety. But if you are secretly leaving devices around the house, recording conversations you are not part of, or using the material later to control, humiliate or blackmail, the legal picture changes dramatically.

This is also where the domestic-violence context matters. NSW and Legal Aid are openly warning about rising tech-facilitated coercive control, and police are increasingly alive to the difference between a victim preserving evidence and an abuser using recording or surveillance as a form of control. That means the same act – pressing record – can be interpreted very differently depending on the broader relationship context.

It is not just making the recording that matters

Another part of the Act catches people by surprise. Under s 11 and related provisions, it is also an offence to communicate, publish or possess records obtained in contravention of the legislation. The legislation site makes clear that possession of an unlawfully obtained record can itself carry up to 5 years’ imprisonment. That is a very practical point for readers: even if the original recording issue is arguable, forwarding the file to friends, relatives, your ex’s employer, or posting clips online can create a much worse legal problem.

Improper use can include posting the recording on social media, sending it to mutual friends to shame or manipulate someone, or threatening disclosure to gain leverage. In real life, those are exactly the sorts of mistakes frightened or angry people make after the recording already exists.

How this overlaps with AVOs, stalking and coercive control

This is one of the strongest reasons for National Criminal Lawyers® to cover the topic in depth. These cases rarely stay as pure surveillance-device questions.

A recording may be used as alleged evidence in an ADVO application. Or the very act of secret recording may be said to form part of a stalking or intimidation allegation. In the right case, repeated covert recording, hidden devices, pressure about what was captured, or threats to release material can be framed as part of coercive control. This overlap has been flagged by lawyers at NCL, and the current NSW policy environment reinforces it. Legal Aid NSW and DCJ are both warning that technology is increasingly being used as a tool of domestic abuse and control, not merely evidence collection.

That is why the practical legal question is rarely just “Was the recording legal?” It is often: What story will police and the court say this recording tells? Self-protection? Or surveillance? Evidence preservation? Or coercive leverage? That narrative can shape everything from charge selection to bail to how a magistrate views the parties.

What about court – can an illegal recording still be used?

Yes, potentially, and this is where readers often get confused.

NCL’s article correctly notes that even illegally obtained recordings can sometimes still be admitted under s 138 of the Evidence Act if the court considers the desirability of admitting the evidence outweighs the undesirability of admitting improperly obtained evidence. In practice, that means a recording may be both legally problematic to make and still useful evidence in the right proceeding. That tension is one of the reasons people should get advice before recording if possible, and definitely before deploying the file in court, family disputes, or police complaints.

For a reader already in trouble, that is a critical point: do not assume “if it proves my point, I can safely use it.” Sometimes you can. Sometimes using it publicly or strategically just proves another offence.

How police usually react to these situations

Police experience in this area tends to track the broader domestic-violence trend: they are much more alert than before to digital control, covert monitoring and “evidence” that is really being weaponised. NSW Police and Legal Aid now treat recording, spyware, tracking and covert digital monitoring as part of a wider landscape of technology-facilitated abuse. That means a reader who thinks, “The recording helps me, so police will obviously be pleased I made it,” may be badly misreading the situation. Police may instead ask: were you lawfully protecting yourself, or were you conducting covert surveillance?

That is especially true where there is already an ADVO, domestic-violence history, or ongoing contact after separation. In those settings, a recording can become just one piece of a much larger allegation pattern.

If you have secretly recorded a conversation, or someone is threatening to use a recording against you, do not assume the law is simple. In NSW, the way the recording was made, why it was made, whether it was reasonably necessary, and what you did with it afterwards can all matter – sometimes enough to determine whether you are protected or prosecuted.

At National Criminal Lawyers®, we regularly advise on covert recordings, digital evidence, AVO overlap, coercive-control allegations and the risks that arise when “collecting proof” turns into its own criminal issue. Early advice can stop a bad situation from becoming much worse.
