Online Impersonation in NSW | AI Voice Cloning, Fake Profiles & Fraud

A fake Instagram account. A cloned voice message. A WhatsApp text from “your boss” asking for an urgent transfer. A dating profile using someone else’s photos. A scammer pretending to be your child and claiming they have lost their phone. None of this feels especially futuristic anymore. It feels routine, which is precisely the problem.

Online impersonation is now common enough that it is affecting ordinary people, workplaces, and families on a large scale. Yet many readers still ask the wrong legal question. They ask: “Is impersonation illegal?” That is understandable, but far too broad. In NSW, the real question is usually this: what was the impersonation used to do?

That distinction matters because “impersonation” is often the method, not the offence itself. If the fake profile, cloned voice, or assumed identity was used to obtain money, gain access, misuse personal information, threaten another person, or cause financial loss, a number of serious criminal offences may arise. If you have already read our article on what counts as online harassment and social media offences in NSW, this article builds on the same idea: digital conduct is judged by what it achieves, not by how casual or modern it appears.

What is online impersonation?

Online impersonation generally involves a person pretending to be someone else through a profile, account, message, email, phone call, or digital identity in order to deceive others.

That can take many forms:

• a fake social media account using another person’s name and photos
• a cloned voice note imitating a relative or employer
• a spoofed email appearing to come from a company executive
• a dating or romance profile built on stolen identity details
• messages sent in another person’s name to obtain money or personal information

Sometimes the purpose is financial. Sometimes it is reputational. Sometimes it is harassment. Sometimes it is all three at once.

This is why online impersonation also overlaps with issues discussed in our article on charged for a text? understanding Commonwealth use carriage service to menace offences. A fake identity is often the vehicle through which the real criminal conduct is delivered.

Is impersonation itself a criminal offence?

Not always as a single stand-alone offence.

That is one of the most important points for readers to understand. NSW criminal law does not simply criminalise all impersonation in the abstract. Liability usually depends on the conduct and purpose behind the deception.

A fake account created as a joke may be foolish and harmful without neatly fitting a single obvious offence. A fake account used to obtain money, manipulate someone into sharing intimate material, access services, cause financial loss, or torment a victim is a different matter entirely.

So the more useful legal question is not “was there impersonation?” but rather “what did the impersonation achieve or attempt to achieve?”

Fraud and deception offences in NSW

The most obvious NSW pathway is fraudunder section 192E of the Crimes Act 1900 (NSW).

In broad terms, a person commits fraud if, by deception and dishonestly, they obtain property, obtain a financial advantage, or cause a financial disadvantage. If someone creates a fake identity, clones a voice, or pretends to be a business, family member, or employer in order to induce a payment or transfer, the conduct may fit squarely within that offence.

There is also section 192G, which deals with making or publishing a false or misleading statement in a material particular with the intention of obtaining property, obtaining a financial advantage, or causing a financial disadvantage. That provision may be relevant where the deception is embedded in false messages, fabricated profiles, or impersonation-based claims.

Readers may see some conceptual overlap with our article on is it a crime to lie to your boss vs lying to the police in NSW. Not every lie is criminal. A lie used dishonestly to secure gain or cause loss is a different legal creature altogether.

Identity offences and misuse of identifying information

NSW law also contains identity-related offences that are highly relevant in the age of fake accounts, stolen profile data, and synthetic onboarding documents.

One important provision is section 192K of the Crimes Act 1900 (NSW), which concerns possession of identification information with the intention of committing or facilitating an indictable offence. That matters because criminal liability may begin before the final fraud or deception is completed.

In other words, a person may attract legal exposure not only because they succeeded, but because they possessed or used identifying information for a criminal purpose.

This is where online impersonation starts to look less like childish catfishing and more like structured digital offending.

Readers interested in simpler forms of identity misuse may also want to compare this with our article on fake IDs, borrowed IDs and underage entry. The technology has evolved, but the legal discomfort around identity-based deception is hardly new.

Carriage service offences and online harassment

Not every impersonation case is about money. Some are about humiliation, threats, revenge, or control.

That is where Commonwealth carriage service offences may become relevant. Section 474.17 of the Criminal Code Act 1995 (Cth) concerns using a carriage service in a way that reasonable persons would regard as menacing, harassing, or offensive. If a fake profile is used to torment, threaten, or psychologically destabilise another person, the conduct may fall within that broader framework.

This sits directly alongside our article on using a carriage service to menace, harass or cause offence. A fake account is not legally interesting because it is fake. It becomes legally interesting because of what it is used to do.

Readers may also wish to compare this with our article on the rise of digital stalking in NSW, because impersonation is sometimes one tool in a broader campaign of harassment or obsessive contact.

AI voice cloning and synthetic deception

AI voice cloning adds a newer and more unsettling dimension.

A short clip from social media, a voicemail, a podcast, or a video post can now be used to generate synthetic speech that sounds plausibly like the real person. If that cloned voice is then used to authorise a payment, manipulate a family member, deceive an employee, or bypass security checks, prosecutors are unlikely to care that the method was fashionable. They will usually care that the conduct was deceptive and dishonestly directed toward gain or advantage.

The key point is that the criminal principle is not new. Fraud remains fraud whether the lie is delivered by forged signature, spoofed email, or cloned voice.

This also overlaps with issues in our article on deepfake pornography and criminal law in NSW, which makes the same larger point: AI may change the delivery system, but it does not dissolve criminal liability.

What should victims do?

Victims of online impersonation often lose precious time deciding whether the conduct is serious enough to act on. Usually, if someone is pretending to be you, your family member, or your employer in order to obtain money, information, or influence, the matter is already serious enough to justify urgent attention.

Evidence should be preserved early. That means screenshots of profiles, usernames, messages, linked accounts, payment requests, voice notes, timestamps, and associated email or phone details. If money has been transferred, the bank should be contacted quickly. Passwords should be changed. Multi-factor authentication should be enabled where possible.

What should you do if you are accused?

Do not keep messaging the complainant to explain yourself, and do not assume deleting profiles or accounts will fix the problem. Screenshots, account records, payment trails, metadata, recovery emails, and linked device data may already exist.

These matters are often more serious than people expect. Depending on the facts, allegations may include fraud, identity-related offences, false statements, carriage service offences, or a combination of several.
