The teen disconnect: what Australia's social ban means for brands beyond borders

The ban stems from amendments to Australia’s Online Safety Act, which now requires platforms to take “reasonable steps” to keep under-16s from holding accounts. Young people are not penalized for bypassing the rules. The legal burden sits entirely with platforms, which face significant fines for noncompliance.

The restricted list includes Facebook, Instagram, Threads, Snapchat, TikTok, YouTube, X, Reddit, Twitch and Kick. Messaging apps such as WhatsApp and Messenger are not included. Gaming and community platforms like Discord and Roblox also remain outside the scope for now, although both have begun strengthening age-assurance features as educators and parents raise concerns.

Importantly, the law focuses on accounts, not raw access to URLs. Many under-16s will still be able to view content while signed out (especially on YouTube, TikTok and Reddit) but without personalized feeds, subscriptions or safety features tied to a profile.

Platforms are not required to use a single verification method. Instead, regulators encourage a layered “waterfall” approach: begin with low-friction signals like device settings, IP location or behavioral patterns (such as accounts that only browse during school hours) and escalate only when necessary to tools such as facial-age estimation or ID checks. The government has also made clear that platforms are not expected to verify every user; they must demonstrate they have made a well-informed assessment of who is likely underage.

To comply:

• Meta began removing suspected underage accounts in November. Users flagged as too young can archive their accounts until they turn 16. Appeals require facial estimation or ID through Yoti.
• TikTok is freezing accounts belonging to 13-15-year-olds, encouraging users to download their data and reinstating profiles at 16. Verification includes ID, selfies and credit-card authorisation.
• Snapchat notified more than 435,000 users and is using ConnectID and k-ID for bank-verified identity checks, document scans and facial estimation.
• YouTube will automatically log out under-16 accounts, a move the platform says removes essential parental controls tied to signed-in use.

Most platforms are pausing (not deleting) accounts. Once users turn 16, their content and connections will be restored.

What brands need to understand now

With the legal framework established, more than a million Australians aged 13-15 have effectively disappeared from follower counts, engagement dashboards and targeting segments. These years often mark the beginning of long-term brand relationships, especially in entertainment, gaming, fashion, beauty and consumer tech. Without access to platforms where teens set trends and influence each other, brands lose the ability to seed early awareness.

Consider a beauty brand that previously built TikTok awareness among 14-year-olds, cultivating interest before those teens had significant spending power, so that by 16 or 17, preferences and loyalties were already forming. That early cultivation window has now closed. Brands must either wait until teens turn 16, when competitors may have already claimed attention, or find entirely different paths to reach them.

Marketers are adjusting in several ways. Some are redirecting messaging toward parents, whose feeds remain accessible and who now serve as decision-makers on behalf of their teens. Others are investing more heavily in gaming environments such as Roblox and Minecraft, which continue to host dense youth communities and remain outside the ban’s scope. 

On Roblox, brands are building immersive experiences: virtual storefronts, branded mini-games, concert venues that let them maintain a presence in spaces where teens still congregate. These platforms offer something major social networks no longer can: direct access to under-16 audiences in environments designed for interaction and play. Offline engagement (once considered a slow channel) is also regaining value, with school programs, sports sponsorships and community events functioning as reliable touchpoints.

Meanwhile, Australian teens have begun exploring alternative platforms. In the days before the ban took effect, apps such as Lemon8 and Yope climbed the Australian app charts as teens searched for workarounds. They are not currently restricted, but regulators have warned that any platform resembling a social network could be added to the banned list, a signal that enforcement will be ongoing, not one-and-done.

There is also a notable change inside the algorithms themselves. Teenagers drive viral formats and meme velocity, often boosting content in ways older audiences do not. With fewer teens active on major platforms, engagement patterns may flatten. Brands accustomed to fast audience acceleration may now see steadier, slower curves: a dynamic that will be visible first in Australia but may foreshadow what happens elsewhere.

For global brands, Australia effectively becomes an early indicator. Media plans will produce different results in Australia compared with the US or UK, offering a rare dataset for modelling future youth-access restrictions.

What the global industry should take from Australia

Australia’s move arrives amid a broader international push to reassess online access for minors. In the UK, the Online Safety Act already requires strict age checks for adult sites, and the regulator Ofcom has pointed to significant increases in VPN usage after enforcement began, raising questions about how enforceable age restrictions actually are. Policymakers have floated additional controls on minors using VPNs, though any such rule would face practical barriers.

In the US, several states, including Utah and Arkansas, have passed laws requiring parental consent for teen social media use and federal proposals such as the Kids Online Safety Act plan to tighten platform responsibilities for protecting minors. Although none go as far as a full ban, Australia provides a model that some lawmakers may now study more closely.

This international momentum raises practical concerns for brands. Youth access may soon vary widely across regions, making unified global strategies harder to execute. If more teens adopt VPNs or privacy tools to bypass restrictions, age- and location-based targeting will become less reliable, complicating media planning and measurement. Safety considerations will also influence channel selection; marketers may be expected to justify not only what they say to young audiences, but where they attempt to reach them.

For CMOs in the US and UK, the relevant question is what happens to your strategy if a ban like Australia’s becomes law in your market? The answer requires more than hypothetical planning. Brands should be testing how campaigns perform without under-16 audiences now, pressure-testing influencer strategies built around young creators and developing concrete alternatives through gaming platforms, family-focused content, school partnerships and brand-owned communities. Australia is a signal to prepare and if additional countries pursue similar restrictions, brands may need to rebuild their youth strategies from the ground up.
