Cyberbullying Laws in Australia: When Online Behaviour Becomes a Criminal Offence

Cyberbullying Laws in Australia: When Online Behaviour Becomes a Criminal Offence

by | 1 Sep 2026

Introduction

The internet has transformed the way Australians communicate. Social media platforms, messaging apps, gaming communities and online forums have made it easier than ever to stay connected. Unfortunately, they have also created new opportunities for harassment, abuse and intimidation.

While many people think of cyberbullying as a schoolyard issue, it affects people of all ages. Adults, employees, business owners, sporting groups and community organisations can all become victims of sustained online abuse.

Importantly, not all offensive online behaviour is a criminal offence. However, when online conduct involves threats, stalking, intimidation, sharing intimate images without consent, using a carriage service to menace or harass, or encouraging serious harm, it may result in criminal charges under Commonwealth or State legislation.

Understanding where the line is drawn between poor online behaviour and criminal offending is essential.

This article explains Australia’s cyberbullying laws, the offences that may arise, how police investigate online conduct, the penalties that may apply and what you should do if you are accused of a cyber-related offence.

What is Cyberbullying?

Cyberbullying generally refers to repeated behaviour using digital technology that is intended to intimidate, threaten, harass, humiliate or seriously distress another person.

Cyberbullying may occur through:

  • Social media
  • Text messages
  • Emails
  • Messaging applications
  • Online gaming platforms
  • Discussion forums
  • Video sharing websites
  • Fake online accounts.

Unlike traditional bullying, online content can spread rapidly and remain accessible indefinitely.

When Does Cyberbullying Become Criminal?

Not every rude, offensive or insulting online comment amounts to a criminal offence.

However, criminal liability may arise where online behaviour includes:

  • Threats of violence
  • Stalking
  • Intimidation
  • Harassment
  • Blackmail
  • Sharing intimate images without consent
  • Encouraging suicide or self-harm
  • Identity theft
  • Fraud
  • Serious online abuse using telecommunications.

The circumstances of each case determine whether criminal charges are appropriate.

Using a Carriage Service to Menace, Harass or Offend

One of the most commonly prosecuted Commonwealth offences involves using a carriage service—such as the internet, a mobile phone or email—in a way that is menacing, harassing or offensive.

Examples may include:

  • Repeated threatening messages
  • Abusive emails
  • Persistent online harassment
  • Threatening social media posts
  • Sending disturbing images.

Whether conduct is criminal depends on the content, context and surrounding circumstances.

Cyberstalking

Cyberstalking is an increasingly common form of criminal offending.

Examples include:

  • Repeatedly contacting someone online
  • Monitoring social media activity
  • Using GPS tracking
  • Creating fake online profiles
  • Sending unwanted messages after being asked to stop
  • Publishing personal information
  • Impersonating another person.

Cyberstalking investigations frequently overlap with stalking offences under State legislation.

Sharing Intimate Images Without Consent

Australian laws prohibit the non-consensual sharing of intimate images in many circumstances.

This is sometimes referred to as “revenge pornography”, although the offending often extends beyond former relationships.

Examples include:

  • Sending intimate photographs to others
  • Uploading intimate videos
  • Threatening to publish intimate images
  • Sharing images obtained without consent.

These offences can attract significant criminal penalties.

Online Threats

Threats made online may be treated in the same way as threats made in person.

Examples include threats to:

  • Assault someone
  • Damage property
  • Kill another person
  • Harm family members
  • Commit serious violence.

Even where the sender claims they “didn’t mean it”, police may still investigate.

Online Defamation vs Criminal Offences

Many people confuse defamation with criminal offending.

Defamation is generally a civil matter involving damage to a person’s reputation.

By contrast, criminal offences usually involve behaviour such as:

  • Threats
  • Intimidation
  • Stalking
  • Harassment
  • Blackmail
  • Identity fraud.

The same online conduct may occasionally result in both civil and criminal proceedings.

Identity Theft and Fake Profiles

Creating fake online identities may also lead to criminal investigations.

Examples include:

  • Impersonating another person
  • Creating fake business accounts
  • Pretending to be someone else
  • Obtaining financial benefit through deception.

The seriousness of the offence depends upon how the fake identity was used.

Cyberbullying in Schools

Cyberbullying frequently affects children and teenagers.

Examples include:

  • Online harassment
  • Exclusion from group chats
  • Circulating embarrassing photographs
  • Threatening messages
  • Fake social media profiles.

Schools often have disciplinary processes, but serious matters may also be referred to police.

Workplace Cyberbullying

Employers increasingly investigate cyberbullying occurring through:

  • Workplace messaging systems
  • Emails
  • Internal chat platforms
  • Social media.

In addition to criminal liability, workplace cyberbullying may result in:

  • Disciplinary action
  • Dismissal
  • Fair Work proceedings
  • Workers compensation claims.

Police Investigations

Cybercrime investigations often involve extensive digital evidence.

Police may obtain:

  • Text messages
  • Emails
  • Social media records
  • IP address information
  • Mobile phone data
  • Cloud storage records
  • Internet provider information
  • Electronic devices.

Deleting content does not necessarily prevent investigators from recovering evidence.

Search Warrants and Electronic Devices

Police may execute search warrants and seize:

  • Mobile phones
  • Laptops
  • Desktop computers
  • Tablets
  • External hard drives
  • Cloud storage accounts.

Digital forensic experts can often recover deleted material and reconstruct online activity.

Common Criminal Charges

Depending upon the circumstances, police may investigate offences involving:

  • Stalking
  • Intimidation
  • Using a carriage service to menace or harass
  • Sharing intimate images
  • Blackmail
  • Identity theft
  • Fraud
  • Threatening violence
  • Breaching Apprehended Violence Orders.

Multiple offences may arise from a single course of online conduct.

Possible Penalties

The penalty imposed depends upon:

  • Seriousness of the conduct
  • Duration of offending
  • Criminal history
  • Harm caused
  • Whether children were involved
  • Whether threats were made.

Possible sentencing outcomes include:

  • Conditional Release Orders
  • Community Correction Orders
  • Intensive Correction Orders
  • Fines
  • Imprisonment.

Serious offences involving threats, exploitation or repeated harassment often attract more severe penalties.

Common Defences

Every case depends upon its individual facts.

Potential defences include:

The Accused Did Not Send the Messages

Police must prove who was responsible for the communications.

This may become an issue where:

  • Accounts were hacked
  • Devices were shared
  • Fake profiles were created
  • Identity theft occurred.

Lack of Intent

Some offences require proof of a particular intention.

Context, tone and surrounding circumstances may become important.

Mistaken Identity

Digital investigations are complex.

Incorrect attribution occasionally occurs where multiple users access the same device or internet connection.

Police Cannot Prove the Case

The prosecution bears the burden of proof.

If reasonable doubt exists regarding any essential element of the offence, the accused must be found not guilty.

What Should You Do if Police Contact You?

If police contact you regarding online behaviour:

  • Remain calm
  • Avoid deleting messages or accounts
  • Preserve electronic records
  • Avoid contacting the complainant
  • Seek legal advice before participating in a formal interview.

Deleting material after becoming aware of an investigation may complicate your legal position.

Will a Conviction Affect My Future?

Yes.

A criminal conviction may affect:

  • Employment
  • Professional licences
  • Working With Children Checks
  • Overseas travel
  • Visa applications
  • Future police checks
  • University enrolment.

The consequences often continue long after the criminal proceedings have concluded.

Why Early Legal Advice Matters

An experienced criminal defence lawyer can:

  • Review the electronic evidence
  • Identify weaknesses in the prosecution case
  • Advise on Commonwealth and State offences
  • Represent you during police interviews
  • Negotiate with prosecutors
  • Prepare sentencing material where appropriate
  • Protect your legal rights throughout the investigation.

Early legal advice frequently results in better outcomes than attempting to manage the investigation alone.
