Starmer copies Australia's under 16s ban and adds new curbs on gaming and AI chatbots, but Australia's own compliance data shows workarounds remain widespread, and the UK has not yet chosen an age verification method.
Keir Starmer confirmed on Monday that the UK will ban social media for all under-16s, then called the obvious critique that children will simply find a way around it "ridiculous" (Guardian live blog). The government's own evidence base for the policy is the Australian under-16s ban that went live in December 2025, but Australia's eSafety Commissioner reported in March 2026 that "a substantial proportion" of under-16s kept or rebuilt their accounts, and the UK has not yet decided which age-assurance method it will require to stop that from happening here.
The model is being billed as "Australia plus." Australia set a minimum age of 16 for accounts on platforms such as TikTok, Instagram, Snapchat, X and Facebook; the UK will copy that baseline and add restrictions the government describes as "world-leading," including parallel age-gating on certain gaming services and livestreaming features, a block on under-18s accessing romantic or sexual AI chatbots, and reported time limits for 16- and 17-year-olds (Guardian explainer). Starmer framed the announcement at a Downing Street press conference on Monday morning as a "big moment for our country" and a "big step" for children's safety.
The live dispute, though, is not whether to ban, but whether it can be enforced. Ofcom, the UK regulator that already oversees the Online Safety Act, has a "highly effective age assurance" toolkit that includes facial age estimation, credit card checks, email-based age analysis and digital ID (Guardian explainer). The government has not said whether platforms will be free to pick from that menu, or whether one method will be mandated, or whether the responsibility will sit with app developers, with app stores, or with device manufacturers. Each of those choices has a different cost, a different privacy trade-off, and a different chance of holding up to the kind of casual circumvention the Australian data describes.
That data is the closest thing to a real-world stress test the UK has. Within days of Australia's ban going live on 10 December 2025, more than 4.7 million social media accounts belonging to under-16s were deactivated, removed or restricted (Guardian: Australia u16 ban). Three months later, the eSafety Commissioner's own compliance update acknowledged that a "substantial proportion" of under-16s had either kept their accounts, created new ones, or used workarounds to bypass age checks (eSafety Commissioner: March 2026 compliance update, PDF). Starmer dismissed the "kids will find a way" line as "ridiculous" at the press conference, but the Australian record is what makes that rebuttal contestable, not what makes it safe (Guardian live blog).
The dissent cuts across the usual political lines. The Molly Rose Foundation, set up by the family of teenager Molly Russell, who took her own life after harmful online content, called a ban "unenforceable" and warned that it "masks the absence of any credible plan to stop childhoods being blighted and young lives lost by out of control algorithms" (Guardian live blog). The intervention matters because it is a critique from inside the child-safety movement, not a free-speech counterblast, and it puts pressure on the government to publish its enforcement plan, not just its ban.
Starmer was personally sceptical of an under-16s ban as recently as the consultation period, citing concerns about pushing children onto the dark web and about a hard "cliff edge" at 16. The consultation closed on 26 May 2026 with more than 116,000 responses; among parents who responded, nine in ten backed a ban (Guardian: consultation results). Starmer has said he changed his views during the consultation, a notable moment for a UK prime minister to publicly credit a campaign rather than arrive at the policy pre-formed, and one that frames the ban as a contestable choice rather than a foregone conclusion.
What the government has not yet decided will determine whether the ban works. The list of services in scope is not final. The age-assurance method, app-store versus app-level responsibility, the penalty regime for non-compliant platforms, and the commencement date are all still to be set. Tech firms are reported to be considering a judicial review, with the Guardian's legal analyst suggesting the process or decision-making could be challenged rather than the policy itself (Guardian explainer). Starmer is heading to France for the G7 immediately after the announcement, then faces the Makerfield byelection on Thursday 18 June 2026, where Andy Burnham is expected to become an MP, a political window the Guardian notes could narrow his room to reset (Guardian live blog). The test of "Australia plus" will not be the press conference. It will be what the UK puts in the statutory text, and whether that text keeps pace with a 14-year-old with a VPN and a fresh email address.
