Problems enforcing Australia’s teen social media ban reflect social media platforms’ weak deployment of tools to run age checks, rather than the limits of the technology, an industry body representing the tech suppliers said.

The comments come as ‌regulators step up enforcement warnings against some of the world’s largest technology companies regarding Australia’s social media ban of users younger than 16, since December, the world’s first such measure.

“The issue is not ​capability, it is application,” Iain Corby, executive director of the Age Verification Providers ​Association (AVPA), said in a statement.

Early shortcomings showed a need for stronger expectations and ⁠enforcement; rather than that, age assurance technology did not work, it added.

Australia’s eSafety Commissioner is investigating Meta, Facebook, Instagram, Google, YouTube, TikTok and Snap over suspected breaches of e-fines of up to A$49.5 million ($35 million) for every breach, and the government says it is gathering evidence to support Federal Court action if compliance does not improve.

The initial rollout ​showed age assurance products can operate accurately at scale, but platforms fail to apply ​them consistently or at key points, such as account sign-up, the association said in a report.

TikTok and ‌Snap ⁠declined to comment, while Meta and Google were not immediately available for comment.

The findings push back against social media companies’ assertions of inadequate age-checking, contending that continued underage access reflects how platforms are using, or not using, the tools available, rather than technical constraints.

Regulatory ​data shows millions of ​suspected underage accounts ⁠have been removed since the law came into force.

However, Australian regulator eSafety has also flagged persistent gaps, such as failures to verify ​age at account set-up, repeated attempts at age checks until users ​pass and ⁠continued reliance on self-declared ages.

In its report, the AVPA said independent testing and early live deployment suggested those weaknesses were driven mostly by platform behaviour, not technology shortcomings.

Key risks to ⁠effectiveness were ​over-reliance on internal age-inference models, which guess a person’s ​age based on online activity, and limited re-verification of existing accounts, it added.

Australia assessed members of ​the AVPA in a sweeping trial before the ban.
