Cyberbullying: 10 Warning Signs Australian Parents Should Know

Cyberbullying is different from traditional bullying. It follows your child home, happens 24/7, and can feel inescapable. Worse, kids often hide it from parents out of shame, fear, or worry that their phone will be taken away.

1 in 3 Australian children will experience cyberbullying. As a parent, knowing the warning signs can help you intervene early—before serious harm occurs.

What Is Cyberbullying?

Cyberbullying is repeated, intentional harm delivered through digital devices. It includes:

  • Sending mean, threatening, or embarrassing messages
  • Spreading rumours online
  • Posting embarrassing photos or videos without consent
  • Creating fake profiles to mock someone
  • Excluding someone from online groups deliberately
  • "Doxxing" (sharing private information publicly)
  • Unlike physical bullying, cyberbullying:

  • Never stops (happens at home, during holidays, at night)
  • Has a wider audience (screenshots shared with hundreds of people)
  • Feels permanent (content lives online forever)
  • Can be anonymous (attackers hide behind fake accounts)
  • 10 Warning Signs Your Child Might Be Experiencing Cyberbullying

    1. Emotional Changes After Using Devices

    Your child seems upset, anxious, or withdrawn immediately after checking their phone or social media.

    What it looks like:

  • Checking phone and suddenly becoming sad or angry
  • Visible stress when notifications appear
  • Refusing to show you what's on screen
  • 2. Avoiding Social Situations

    They stop wanting to go to school, social events, or activities they previously enjoyed.

    What it looks like:

  • Stomach aches on school mornings
  • Making excuses to skip activities
  • Withdrawing from friend groups
  • 3. Secretive About Online Activity

    Suddenly protective about their phone or computer. Won't tell you who they're talking to.

    What it looks like:

  • Quickly closing apps when you enter the room
  • Refusing to share passwords (when they did before)
  • Deleting browser history constantly
  • 4. Sleep Problems

    Difficulty falling asleep, staying asleep, or nightmares. Exhausted during the day.

    What it looks like:

  • Up late on phone (checking for new attacks)
  • Tired and irritable during the day
  • Dark circles under eyes
  • 5. Changes in Eating Habits

    Either loss of appetite or emotional eating as a coping mechanism.

    6. Declining Academic Performance

    Grades dropping. Trouble concentrating. Missing assignments.

  • Can't focus on homework
  • Used to be engaged, now seems checked out
  • Teachers reporting changes in behaviour
  • 7. Self-Esteem Issues

    Negative self-talk. Saying they're ugly, stupid, or worthless. Body image concerns.

    What it looks like:

  • "Everyone hates me"
  • "I'm so stupid"
  • "I wish I looked different"
  • 8. Physical Symptoms

    Headaches, stomach aches, anxiety symptoms (rapid heartbeat, sweating, panic).

    9. Isolation from Family

    Spending more time alone. Not participating in family activities. Withdrawn during meals.

    10. Mentions of Self-Harm

    Any talk of wanting to hurt themselves, not wanting to live, or feeling hopeless.

    ⚠️ This is an emergency. Take it seriously every time.

    What To Do If You Suspect Cyberbullying

    Step 1: Create a Safe Space for Conversation

    Don't:

  • "Why didn't you tell me sooner?"
  • "Just ignore them"
  • "It's not that bad"
  • Take away their phone immediately (this punishes the victim)
  • Do:

  • "I've noticed you seem upset. Want to talk?"
  • "You're not in trouble. I'm here to help."
  • "That must feel awful. I'm so glad you told me."
  • Listen without judgment
  • Step 2: Document Everything

    Take screenshots of:

  • Harassing messages
  • Comments
  • Posts
  • Fake profiles
  • Any threats
  • Include timestamps, usernames, URLs. This is evidence you may need.

    Step 3: Report to Platforms

    All major platforms have cyberbullying reporting:

  • Instagram: Report → Bullying or harassment
  • TikTok: Report → Bullying
  • Snapchat: Press and hold message → Report
  • Facebook: Report → Harassment
  • Platforms are legally required to respond in Australia.

    Step 4: Contact the School

    If the bully is a classmate, the school has a duty of care to intervene—even if it happens outside school hours.

    Bring documentation. Ask for:

  • Meeting with principal/counsellor
  • Involvement of other parents if appropriate
  • Safety plan for your child
  • Consequences for the bully
  • Step 5: Report to eSafety Commissioner

    For serious cases, report to Australia's eSafety Commissioner:

  • esafety.gov.au/report
  • They can force removal of harmful content
  • Can work with police for threats/illegal content
  • Step 6: Block and Limit Contact

  • Block the bully on all platforms
  • Make accounts private
  • Change usernames if necessary
  • Temporarily limit social media access (with child's input)
  • Step 7: Support Your Child's Wellbeing

  • Consider counselling (Kids Helpline: 1800 55 1800)
  • Keep communication lines open
  • Rebuild self-esteem through positive activities
  • Monitor for signs of depression/anxiety
  • Preventing Cyberbullying

    For Kids

  • Think before you post. Would you want this said about you?
  • Don't forward mean messages. That makes you part of the problem.
  • Stand up for targets. "That's not cool" goes a long way.
  • Tell an adult. It's not snitching—it's safety.
  • For Parents

  • Talk regularly about their online life
  • Use tools like Manaia to detect concerning patterns without reading messages
  • Model good digital citizenship (you're online too!)
  • Have a plan before crisis hits
  • How Manaia Helps Detect Cyberbullying

    Manaia's AI safety reports analyse patterns without reading messages:

    What Manaia detects:

  • Sudden increase in social media time (could indicate compulsive checking after attack)
  • Access to support sites (Kids Helpline, eSafety resources)
  • Blocking social media during school hours but unblocking after (sign of stress)
  • Pattern changes (used to use TikTok, suddenly stopped—why?)
  • What it tells you:

    "Emma's social media use increased by 60% this week, mainly late at night. She visited the Kids Helpline website twice. Suggested conversation starter: 'I noticed you've been on your phone more lately. Everything okay with your friends?'"

    This gives you insights without invading privacy—a critical balance with teens.

    When to Involve Police

    Contact police if:

  • Threats of violence against your child
  • Sexual harassment or explicit images
  • Stalking or sustained harassment
  • Blackmail or extortion
  • Hate speech based on race, religion, sexuality, disability
  • Cyberbullying can be a crime in Australia under various laws including Criminal Code Act.
