Reddit High Court Challenge to Under-16 Social Media Ban

Australia's under-16 social media ban faces its first major legal challenge in the High Court, with hearings beginning Tuesday 3 November 2026. Reddit and the Digital Freedom Project, led by NSW Libertarian MP John Ruddick, argue the world-first law impermissibly burdens the implied freedom of political communication by shutting under-16s out of civic discourse. The case is the first judicial test of a ban that has already forced ten platforms to suspend more than five million accounts since it took effect on 10 December 2025.

What Is Australia's Under-16 Social Media Ban?

The Online Safety Amendment (Social Media Minimum Age) Act 2024, passed by the Australian Parliament on 29 November 2024, prohibits minors under 16 from holding accounts on designated social media platforms. The law took effect on 10 December 2025, requiring ten platforms — Snapchat, TikTok, YouTube, Facebook, Instagram, Reddit, Kick, X, Twitch and Threads — to deactivate or suspend accounts they reasonably believed belonged to users under 16. It was the first such national ban in the world and is now the subject of social media age restrictions litigation.

Since enforcement began nearly 11 months ago, more than five million accounts across those platforms have been blocked, according to Prime Minister Anthony Albanese. The law imposes penalties on companies that fail to take reasonable steps to prevent under-16s from using their services, amending the Online Safety Act 2021.

Why Reddit and the Digital Freedom Project Are Challenging the Law

Reddit's counsel, Perry Herzfeld SC, told the High Court the 2024 legislation was rushed through Parliament in a week with only 24 hours for submissions, producing what he called “ill-thought-out, over-broad legislation.” He said the ban prevents under-16s from posting, commenting or upvoting in forums such as r/Australia, and cited Reddit's “Ask Me Anything” political sessions as evidence that platforms are a common source of political news. “Teenagers cannot engage with parties' youth wings or political AMAs,” Herzfeld argued.

The Digital Freedom Project contends less restrictive alternatives exist, including a proposed digital duty of care, notification limits and parental controls. The group also faces a standing challenge after its two teenage plaintiffs withdrew in July, meaning the Commonwealth disputes whether it can bring the case.

Government Defence and Legal Experts' Views

Commonwealth barrister Joanna Davidson SC argued that any burden on political communication is indirect and modest, applying only to “electors,” and is justified by the need to protect children from online harms. She said engagement-maximising design features — autoplay, recommendations and default notifications — are shared across all ten banned platforms and compound risks such as poor sleep and depression.

Justice Gleeson questioned how politically engaged most teenagers are, while constitutional law expert Professor Luke Beck of Monash University said the government has a strong case. Constitutional law scholars remain divided, with some arguing the ban sets a dangerous precedent for digital rights.

What a High Court Ruling Could Mean Globally

The High Court's decision could set a precedent for other countries weighing age-based social media restrictions. If the challenge succeeds, it may force Australia to rewrite the law or adopt a digital duty of care model. A government victory would reinforce the ban's world-leading status and embolden jurisdictions such as the UK, France and several US states considering similar measures.

The outcome also has implications for age verification technology and how platforms implement account-level restrictions without disproportionately excluding young people from public debate.

What Happens Next

Arguments continue Wednesday, with the Commonwealth to complete its case. The High Court will then consider whether the ban's burden on political communication is justified by child protection. A decision could reshape Australia's digital landscape and set a global benchmark for online safety regulation.
