Why Australia's under-16 social media ban could backfire
The intent is sound. The mechanism is blunt. Once minors present as adults to evade the ban, the safety systems that protect them stop working.
On 10 December 2025, Australia will introduce regulations requiring designated age-restricted social media platforms to prevent anyone under 16 from creating or maintaining an account. The objective is to reduce exposure to harmful content and improve online safety for young people.
The intent is sound, but the mechanism is blunt and risks weakening safeguards that depend on accurate age identification. While penalties apply only to platform providers, and parental consent cannot override the minimum age, the central issue is whether the approach delivers the intended safety outcome.
What the government is trying to achieve
The government aims to:
- reduce exposure to harmful or inappropriate content
- limit negative mental health impacts
- restrict commercial influence over minors
- establish a safer online baseline
They expect forced sign-outs, account deactivation and restricted features to create a safer digital environment. The question is not the intention but the operational impact.
The core problem: identification enables protection
Modern safety systems rely on knowing whether a user is a child or an adult. Platforms such as Meta and Google already enforce restrictions including no personalised advertising to minors, reduced data collection and profiling, controlled recommendation exposure, limits on communication features, wellbeing tools and adjusted handling of creators under 18. These protections largely depend on age being visible to the platform.
Google’s December update shows how significant age visibility is. Under-16s in Australia will be automatically signed out of YouTube. They can still watch while signed out but lose access to subscriptions, comments, uploads, playlists and wellbeing features such as “Take a Break” and “Bedtime Reminders”. Parents lose supervisory controls. Creators under 16 cannot upload or manage channels, and channels operated by under-16s may no longer be viewable. Google determines age using the account and other age-assurance signals. This framework depends on accurate age identification.
What happens when minors become “anonymous adults”
Children often attempt to bypass restrictions, a pattern observed across major platforms over many years. Typical workarounds include entering a false age at sign-up, using a parent’s or sibling’s account, VPNs, alternate devices and sideloaded apps (installed outside official app stores). These behaviours are well-documented and reduce platforms’ ability to distinguish minors from adults.
Once a child presents as an adult, the system is much less able to apply child-safety filters, advertising restrictions, data-minimisation rules, communication controls, recommendation limits or wellbeing settings. In system terms, they are treated as adults by algorithms and ad infrastructure. This is a risk scenario rather than a measured outcome, but it aligns with how digital systems behave when identification signals deteriorate.
System-level risk from reduced visibility
From a systems perspective, when accurate age signals erode, safety mechanisms tend to weaken. The likely consequences include:
- reduced effectiveness of content-safety systems
- inappropriate content surfacing for minors
- misclassified ad delivery
- increased data collection under adult rules
- degraded reporting accuracy
- weaker regulatory oversight
- higher commercial and compliance risk for advertisers and platforms
When identification drops, risk increases. The current regulatory approach increases the conditions under which age becomes harder to verify.
A more effective path: tiered, accountable access
This is an argument for precision over blunt restriction, not for unrestricted access. A more effective approach would preserve age visibility and enforce:
- verified age assurance
- restricted experiences for minors
- curated and context-appropriate content
- strict data minimisation
- controlled communication features
- no personalised advertising
- transparent reporting
- meaningful penalties for breaches
This model allows platforms to identify minors and apply protections designed specifically for them. The blanket ban removes the foundation these protections depend on.
Key policy references
For transparency, the policy documents and platform rules underpinning this analysis: the Online Safety Amendment (Social Media Minimum Age) Act 2024; Social Media Age Restriction Hub; the AANA Children’s Advertising Code; Meta Teen Privacy and Advertising Restrictions; Google and YouTube’s Under-16 enforcement policies; and the OAIC Children’s Online Privacy Code (in development). These demonstrate that significant protections already exist, and they depend on retaining accurate age signals.
Why precision matters more than prohibition
Online safety requires accuracy, not blunt exclusion. Reducing visibility of who is a child weakens existing protections, increases inappropriate content and advertising exposure, creates more anonymous or misclassified users, complicates regulatory oversight and elevates compliance risks for advertisers and platforms.
On balance, the mechanism may generate risks that outweigh its benefits. A safer system depends on maintaining age visibility and applying strict, targeted protections to what minors see, how data is handled and how advertising systems treat them. In practice, precision usually outperforms blunt force.
