If you asked most Australian parents where cyberbullying happens, they’d probably say Instagram or TikTok. The honest answer is: most of it happens in group chats — WhatsApp, iMessage, Snapchat groups, and similar. These private spaces are invisible to parents, invisible to platforms, and largely invisible to schools.
That doesn’t mean group chats are a problem to be solved. They’re a normal, genuinely valuable part of how Australian teenagers manage their social lives. But they’re also the most common location for the most damaging forms of cyberbullying, social exclusion, and peer pressure — precisely because no one is watching.
What Kids Are Actually Using
WhatsApp is dominant for secondary school students, particularly from Year 8 upward. Class group chats, close friend groups, sports teams, and party planning all happen primarily on WhatsApp for many Australian teenagers. It’s free, end-to-end encrypted, and owned by Meta. WhatsApp’s minimum age in Australia is 16, but there’s no meaningful age verification and plenty of younger students use it.
iMessage group chats are heavily used by primary school-age children and younger secondary students. Parents are often more visible in iMessage threads, which can push older kids toward WhatsApp as they want more independence.
Snapchat groups sit alongside WhatsApp for many teenagers. The perception that messages disappear makes some kids more willing to share things they shouldn’t — but that perception is largely a myth. Screenshots are easy, and while Snapchat notifies you when one is taken, it can’t prevent it.
Instagram group DMs are used for close friend groups, particularly among girls.
The typical Year 9 or 10 student is in multiple overlapping group chats simultaneously: a class group, a close friends group, a sports or activity group. They’re managing several social contexts at once, and the apps are how they do it.
What’s Good About Group Chats
Group chats are genuinely useful — and acknowledging this makes for a more honest conversation with your child than treating them as a problem to manage.
They’re how teenagers coordinate their social lives. They maintain friendships across distances. They provide belonging and community. For many shy or anxious kids, typed communication in a group is actually more comfortable than face-to-face. Class group chats often carry genuine academic value — sharing homework questions, flagging due dates, helping each other prepare for exams.
Keep this in mind as you read the risks. The goal isn’t to remove group chats. It’s to help your child navigate them well.
What Are the Real Risks?
Cyberbullying — the primary location
Private group chats are the main location for the most damaging forms of cyberbullying in Australia. They’re invisible to adults. The group dynamic creates a pile-on effect — one person starts, others join in, bystanders stay silent out of fear. Being targeted in a group chat isn’t dealing with one unkind person; it’s dealing with the apparent agreement of everyone in a group the child cares about.
Being excluded from a group chat — or discovering a separate chat exists where you’re being discussed — is experienced as profound social rejection. By the time a parent or teacher finds out, significant harm has often already been done.
The “other” group chat
This deserves its own mention because it’s so common and so painful. There is the official class or friend group everyone’s in. And then there’s a separate group chat without one or two specific people, where those people are discussed, mocked, or excluded.
The person left out often knows, or suspects, it exists. They can feel it in the way conversations go quiet when they arrive. They hear things that were clearly said somewhere they weren’t included. But they can’t prove it, and they can’t confront it.
This is one of the most common forms of social exclusion in Australian secondary schools right now. It’s worth naming it with your child — not to plant paranoia, but so they know you understand how it works, and that they can come to you if it happens.
Pressure and oversharing
The private, intimate feel of a group chat lowers inhibitions. Teenagers share things in group chats they would never say publicly: personal information, opinions about others, rumours, and images. The assumption that the chat is private is often wrong. Screenshots travel. People get added and removed from groups. What felt like a safe space last week may have different members this week.
Image sharing
Group chats are a primary vector for sharing intimate images — both real photographs and AI-generated content. Images shared in a “private” group have a well-documented tendency to spread far beyond the original recipients. Australia has image-based abuse laws at both state and federal levels, and they apply to minors. Sharing intimate images of a person under 18 is a serious criminal matter regardless of who took the original image.
What Parents Can Do
Know which apps your child uses for group chats. Just ask. Most kids will tell you honestly.
Know roughly which groups they’re in — not the content, just the existence. “Class group, footy team group, close friends group” is useful information. You’re not asking to read the messages; you’re asking to understand the landscape of their social life.
Establish the screenshot rule. Anything sent in a group chat can be screenshotted and shared. This applies to words, images, and voice messages. Say it plainly: once it’s sent, you’ve lost control of it.
Talk about the bystander role. In most group chat pile-ons, the majority are silent bystanders. Being a bystander is a choice. Your child doesn’t have to publicly defend the person being targeted — but they can privately message that person to check in, or tell a trusted adult. Doing something small is better than doing nothing.
Acknowledge the “other chat” phenomenon. Let your child know you’re aware these exist, that being excluded from one is genuinely painful, and that they can talk to you about it without judgement.
WhatsApp Privacy Settings — Step by Step
- Settings → Privacy → Last Seen & Online: set to “My Contacts” or “Nobody”
- Settings → Privacy → Profile Photo: set to “My Contacts”
- Settings → Privacy → About: set to “My Contacts”
- Settings → Privacy → Groups: set to “My Contacts” — the most important one. Only people in your child’s contacts can add them to a group.
- Settings → Privacy → Status: set to “My Contacts”
- Settings → Privacy → Read Receipts: turning off the blue ticks removes some social pressure around response time
If Your Child Is Being Targeted in a Group Chat
Screenshot everything before doing anything else. Before leaving the chat, blocking anyone, or deleting messages — screenshot. Once you leave or messages are deleted, that evidence is gone.
Report to the school. Even if it happened outside school hours on personal devices, Australian schools have authority to respond to cyberbullying that affects student wellbeing. Contact the year level coordinator or principal directly.
Report to the eSafety Commissioner at esafety.gov.au if the content involves images, is severe or ongoing, or if school intervention doesn’t resolve it.
If images were shared: contact the police. Sharing intimate images of a person under 18 is a criminal offence under Australian law. This is not an overreaction — it is the appropriate response.
If Your Child Is Doing the Bullying
The pile-on dynamic means kids participate in bullying behaviour they would never initiate alone. “I just sent a laughing emoji” and “everyone else was doing it” are common explanations — both worth addressing calmly rather than dismissing.
The laughing emoji counts. Being a visible, approving bystander is part of the pile-on, even if it feels passive. A group chat culture where cruelty has become normal is worth challenging — not with a lecture, but with a genuine question: “How do you think that person feels reading that?”
The Bottom Line
Group chats aren’t going away. They’re how Australian teenagers live their social lives, and they do genuine good. The risks are real but not mysterious.
You don’t need to monitor every message. You need your child to know the rules of the road: that screenshots travel, that bystanders make choices, that being excluded hurts and they can tell you, and that certain things — especially images — have consequences that outlast the chat they were shared in.
That’s a few honest conversations, one privacy settings review, and an open door. That covers most of the ground that matters.
