From December 10, 2025, over a million Australian teenagers will lose access to their social media accounts. This is a world-first legislation that bans under-16s from platforms like TikTok, Instagram, YouTube, and Snapchat.

If any part of your marketing strategy involves reaching young Australians through social media, this directly affects you. Although, the ripple effects will also touch organic reach, influencer partnerships, content trends, and audience demographics across the board.

This is not a drill, platforms face fines of up to $50 million AUD for non-compliance. If you have kids, they likely already have deactivation notices in their social platform notifications.

Here’s what’s changing, who it affects, and what you can do about it.

When is the Social Media Ban Happening?

The Online Safety Amendment (Social Media Minimum Age) Act 2024 amended Australia’s Online Safety Act to introduce a minimum age of 16 for social media accounts. The law takes effect on December 10, 2025.

Australians under 16 cannot create or maintain accounts on age-restricted social media platforms. The onus is on platforms, not parents or teenagers, to take “reasonable steps” to prevent under-16s from having accounts. And unlike age restrictions in other countries, there’s no parental consent exemption. Parents can’t sign a permission slip to let their 14-year-old keep their TikTok account.

The penalties for non-compliance are serious. Platforms that fail to take reasonable steps face fines of up to $49.5 million AUD per breach. That’s not a typo—and it’s why platforms are moving fast.

Meta began sending deactivation notices to Australian users suspected of being under 16 in late November, warning them to download their data and delete their accounts before the ban takes effect. Other platforms are rolling out age verification measures, with Snapchat introducing bank-linked ID checks through ConnectID.

A High Court challenge was filed on November 26th by the Digital Freedom Project, arguing the ban restricts young people’s freedom of political communication. But the Communications Minister Anika Wells has confirmed the government remains “steadfastly on the side of parents, and not of platforms.” The ban is proceeding as scheduled at this stage.

Which Platforms Are Affected

As of November 21, 2025, the eSafety Commissioner confirmed the following platforms are age-restricted:

Facebook
Instagram
TikTok
YouTube
Snapchat
X (formerly Twitter)
Reddit
Twitch
Kick
Threads

These are the platforms where under-16s will no longer be able to hold accounts from December 10.

Platforms NOT affected include WhatsApp, Messenger, Discord, YouTube Kids, Roblox, Pinterest, and LinkedIn. Online gaming platforms have a general exclusion, and standalone messaging apps that don’t have social-media-style features are also exempt.

How This Affects Your Business

The impact of Australia’s social media ban depends on how closely your audience skews young. Let’s break it down.

If You Market Directly to Under-16s

If your business targets children or early teenagers (education providers, kids’ entertainment, youth sports clubs, children’s retail, or gaming) you’re facing the most direct impact.

Your primary social channels for reaching this audience are now off-limits. There’s no workaround. Under-16s won’t be on Instagram, TikTok, or YouTube (the main platform, not YouTube Kids) from December 10. If they were a significant part of your social following, you’ll see engagement drop.

What to do first: Check your audience demographics in Meta Business Suite, TikTok Analytics, and YouTube Studio. What percentage of your followers or viewers are under 18? Platforms don’t show data for under-13s, so under-18 is your proxy. If that number is substantial, you need a channel diversification plan now.

If You Market to Youth-Adjacent Audiences

Maybe you don’t target under-16s specifically, but your audience skews younger such as 16 to 24-year-olds, families, or parents of teenagers. You’re not exempt from the effects.

Here’s what to watch for:

Reduced organic reach. As under-16s leave platforms, overall user numbers drop. Algorithms will adjust, and competition for attention among remaining users will shift. Your reach may change even if your target audience is still on the platform.

Content trend shifts. Teenagers drive a lot of social media trends. As under-16 users leave platforms, the content landscape will evolve. Trends that originate with younger users will slow down or disappear.

Family content dynamics. If your content gets shared within families, parents sharing with kids, or vice versa, that organic amplification loop may weaken.

Don’t panic at initial dips in your metrics after December 10. Give it four to six weeks for the dust to settle before making dramatic strategy changes, remember it’s hitting your competitors too.

Broader Implications for All Businesses

Even if you don’t market to young people at all, you’ll feel some effects as some percentage of your current reach and engagement will be from those who accounts are being deactivated.

Platform algorithms will recalibrate as user bases shift. Content saturation may increase as the same number of brands compete for fewer eyeballs. And the cultural role of social media in Australia is changing, “going viral” has never been a marketing strategy, but it just got a bit harder.

What to Do Now if You’re Affected

Whether you’re directly affected or just want to stay ahead of the curve, here are six practical steps to take before and after December 10.

Audit your current audience demographics. Log into Meta Business Suite, TikTok Analytics, YouTube Studio, and any other platform analytics you have access to. Document your current follower counts and engagement metrics as a baseline. Note what percentage of your audience falls into younger age brackets. This gives you a clear picture of your exposure.
Assess your content strategy. Content designed to “go viral” needs rethinking. Your content strategy should focus on what resonates with your actual target audience, not what might get picked up by teenagers scrolling at 11pm.
Monitor and adapt. Track your performance metrics weekly through December and January. Don’t overreact to one bad week. Set a review point for late January to assess the real, sustained impact and make informed decisions about your strategy going forward.
