“Charged for a Text?” Understanding Commonwealth ‘Use Carriage Service to Menace’ Offences
You’re angry. You send a heated text message or leave a threatening voicemail only to find police knocking at your door days later. Under federal law, this isn’t just bad judgment. It might be a criminal offence under section 474.17 of the Criminal Code Act 1995 (Cth) the offence of using a carriage service to menace, harass or offend.
At National Criminal Lawyers®, we see more and more clients charged under this Commonwealth provision. Many have no prior record and often didn’t intend for their words to be taken seriously. But the law focuses not just on intent; it focuses on how a reasonable person would interpret your message.
This blog unpacks the legislation, the case law, and what to do if you’re charged with a serious online communication offence.
What Is the Offence?
Section 474.17(1) of the Criminal Code (Cth) makes it an offence if:
A person uses a carriage service (e.g. phone, email, text, social media), and does so in a way that reasonable persons would regard as menacing, harassing or offensive in all the circumstances.
Penalties include:
- Up to 3 years’ imprisonment (s 474.17(1))
- 5 years’ imprisonment for aggravated circumstances (e.g. targeting a child)
“Carriage service” includes:
- Text messages
- Phone calls
- Social media messages (Facebook, Instagram, Twitter/X)
- Emails
- Voice notes
What Must the Prosecution Prove?
There are two key elements:
- Use of a carriage service;
- Conduct that is menacing, harassing or offensive from the perspective of a reasonable person.
There must also be a fault element:
- Either the accused intended the conduct to be menacing; OR
- Was reckless to the risk it might be.
Notable Case Law Examples
R v Arkle [2022] NSWDC 523
Arkle was convicted for leaving 21 voicemail messages on his stepmother’s phone over a short time, including threats like “whipper snipper to the face.” He claimed it was a joke and he was intoxicated. The Court rejected this, finding a reasonable person would consider the messages menacing, regardless of his intent to “joke.”
Key Insight: The sender’s motive or intoxication does not excuse the message if a reasonable person would be alarmed.
Spence v R [2020] NSWDC 442
Spence made repeated calls and messages to a former colleague, including insults and professional threats. While the lower court focused on the “menacing” nature of earlier messages, the appeal court clarified that even unwanted, repeated messages may qualify as harassment, even without express threats.
Key Insight: High-frequency messages alone, even without violent content, can still qualify as criminal harassment.
Hastings Fredrickson (No 1) [2015] NSWDC 114
Fredrickson emailed non-consensual sexual content involving an identifiable woman to his friends. The court found his conduct offensive under s 474.17 due to the humiliating, degrading, and misogynistic nature of the emails.
✉️ Key Insight: The law applies even when material is sent privately, not publicly, if the content is severe.
Legal Definitions: What Is “Menacing” or “Harassing”?
- Menacing = threats or conduct that would cause a reasonable person to feel afraid, coerced, or seriously distressed.
- Harassing = repetitive or unwanted behaviour intended to trouble or disturb.
- Offensive = content likely to cause serious emotional or psychological harm, not merely rude or annoying.
“Menace” is not defined in s 474.17, but other sections (like s 138.2) define it as threats of conduct that is “detrimental or unpleasant”.
How Do Courts Decide These Cases?
Courts apply an objective test:
- Would a reasonable person view the communication as menacing, harassing, or offensive in the full context?
They also assess:
- The volume of messages
- The language used
- Whether the sender showed recklessness or repeated aggression
- The history between the parties
Courts consider mental health or intoxication at sentencing, but these rarely defeat the charge itself.
These terms, definitions and exceptions are all incredibly context-dependent and often unclear, which makes the need for an experienced, well-versed criminal defence lawyer that much more critical in ensuring you get the justice you deserve.

What Are the Defences?
Some common defences include:
- Denial of authorship (e.g. someone else sent the message)
- Lack of intent or recklessness
- Reasonable excuse (e.g. urgent warnings)
- Constitutional defences (rare), such as implied freedom of political communication
FAQs
Can I be charged for messages sent during a breakup or argument?
Yes. Highly emotional messages can still breach the law if they cross the threshold.
Does it matter if I was drunk or joking?
No. Courts focus on how the message would be seen by a reasonable person.
Can I be jailed for one text?
Yes, if the content is sufficiently menacing or part of a larger pattern.
