Starmer's reported 'Australia plus' package adds UK restrictions on gaming app chats, late night scrolling for 16 18s, and romantic AI chatbots to Australia's December 2025 under 16 model.
The UK government is preparing to ban under-16s from TikTok, Instagram and X, and to extend new restrictions into gaming apps, late-night scrolling for 16-18-year-olds, and AI chatbots that allow romantic or sexual roleplay. The package, reported as an "Australia plus" model, would go measurably beyond the Australian framework that took effect in December 2025, but it lands with the harder question unanswered: how ministers intend to enforce any of it.
Under the plan, the headline measure is a UK-wide bar on under-16s opening accounts on the largest social platforms, including TikTok, Instagram and X, with others yet to be confirmed, according to a Guardian report citing sources briefed on the announcement. That core mirrors Australia's December 2025 law, which set a minimum age of 16 for holding accounts on ten named platforms — TikTok, YouTube, Instagram, Reddit, Facebook, X, Threads, Snapchat, Twitch and Kick — and forced those companies to build age-assurance systems at sign-up.
The "plus" is where the news sits. Three distinct additions sit alongside the platform ban, each with its own age band and its own product surface.
On gaming, popular apps that fall outside the headline social media list will face new restrictions, including the removal of the option to chat with strangers. The Guardian's reporting indicates the changes will apply where the game is likely to be used by under-16s, a wider net than the platforms list suggests, and one that will pull in chat features inside many mainstream mobile titles.
On older teenagers, 16-18-year-olds will face a new restriction on late-night scrolling, with platform-level defaults expected to cap use during overnight hours. The mechanism has not been confirmed in the captured reporting, and a default cap is a different policy lever from a statutorily mandated curfew, a distinction that will shape whether the rule is a setting parents can override or a limit the platforms must enforce.
On AI, the package includes a UK-specific bar on a specific class of chatbot: products that let users roleplay romantic or sexual conversations, with the under-18 age ceiling applied even to the older teen cohort that the social media ban exempts.
The Australian anchor matters because the comparison is doing real work in the announcement. Australia's December 2025 law set the under-16 bar and named ten platforms, but it did not touch gaming chat, did not impose a late-night default for older teens, and did not address AI companion products. By naming the additions explicitly, the UK is signalling that the "plus" is not rhetorical, and that the package is a set of policy choices that did not exist in the Australian baseline.
The enforcement problem is the structural spine of the announcement. The Guardian's reporting, which describes the policy as something the prime minister "understands" he will set out, indicates that ministers believe primary legislation may be needed for the full package. The Children's Wellbeing and Schools Act already gives the UK some powers to act on platforms used by children, but a platform-level age check on a closed account, a default overnight cap on a 17-year-old's feed, and a category ban on a class of AI chatbot each raise separate questions of legal authority, technical feasibility, and privacy trade-offs that the existing statute does not obviously answer.
Age assurance is the operational bottleneck. Australia's experience is the relevant case study: the December 2025 law required platforms to verify age at sign-up, and the choice of method — whether document upload, third-party age estimation, or behavioural inference — is a privacy and accuracy trade-off the UK will inherit. The new ground the UK is breaking has no Australian precedent: an overnight default for older teens, and a category ban on a chatbot class defined by what users do with it.
The open questions are concrete. Will a 15-year-old need to upload a passport to open an X account, or will the platform rely on a third-party age check that estimates age from a selfie? Will the late-night default apply to Instagram Reels and TikTok For You feeds, and will parents be able to extend the window with a verified adult account? Will an AI chatbot that allows romantic roleplay be defined by its marketing, its model behaviour, or its terms of service, and which of those definitions survives a judicial review?
The announcement, when it lands, will give ministers a public platform to argue that the UK has moved past Australia on the age question and past its own previous briefings on the scope of online restrictions for under-18s. The follow-through, which is what changes a 15-year-old's Tuesday evening, will depend on legislation, on age-assurance vendors, and on the platforms' willingness to build features they have so far avoided. Those are the moving parts, and the announcement is only the first of them.
