The Australian social media ban for under 16s is facing a major legal challenge as the country’s government defends its landmark online safety legislation before the High Court.
On Wednesday, 4 November 2026, government lawyers argued that restricting children’s access to social media accounts is necessary to protect their mental health, wellbeing and development.
The legislation, which came into effect on 10 December 2025, made Australia the first country to introduce a nationwide minimum age of 16 for accounts on several major social media platforms.
However, the restrictions have faced criticism from technology companies and digital rights campaigners.
Reddit and the Sydney-based Digital Freedom Project have challenged the legislation, arguing that it places unreasonable limits on political communication.
The two-day High Court hearing concluded on Wednesday, with a judgement expected in the coming months.
The outcome could influence how other countries approach online safety and children’s access to social media.
Why Is Australia Defending Its Social Media Ban in Court?
Australia’s government believes that social media platforms expose children to risks that can affect their mental and physical health.
Government lawyers told the High Court that some platform features encourage excessive engagement and prolonged screen time.
They argued that these features can contribute to several problems, including sleep disruption, anxiety and compulsive social media use.
Government lawyer Joanna Davidson identified seven categories of potential harm associated with social media platform design.
These included addictive use, disrupted sleep, depression, anxiety, suicidal thoughts, disordered eating, and worsening symptoms of ADHD.
The government argued that protecting children from these risks provides a legitimate reason for introducing age restrictions.
However, the extent to which social media directly causes particular mental health problems remains an area of scientific research and debate.
The court must consider whether the restrictions are constitutionally justified.
What Is Australia’s Under-16 Social Media Ban?
Australia introduced its social media minimum-age legislation in December 2025.
The law requires certain social media companies to take reasonable steps to prevent Australian children younger than 16 from creating or maintaining accounts.
The restrictions apply to ten major platforms:
- Threads
- Snapchat
- TikTok
- YouTube
- X, formerly Twitter
- Twitch
- Kick
The legislation places responsibility for compliance on technology companies rather than children or their parents.
Children who attempt to use restricted services are not personally fined.
Parents are also not subject to penalties simply because their children attempt to access social media.
Instead, the government expects platforms to introduce effective age-assurance systems and remove accounts belonging to users below the minimum age.
Companies that fail to take reasonable steps to comply can face substantial financial penalties.
Why Is Reddit Challenging Australia’s Social Media Restrictions?
Reddit is one of the organisations challenging the law.
The American online discussion platform argues that the restrictions interfere with young people’s ability to communicate and participate in public debate.
Its lawyers told the High Court that the legislation is too broad and fails to distinguish sufficiently between different types of online services.
Reddit also argues that it should not have been included among the ten restricted platforms.
The company maintains that its discussion-based service differs from some other social media platforms.
Reddit’s legal representatives have questioned whether the government has demonstrated that the restrictions are appropriately targeted.
The company says it supports protecting young people online but believes alternative approaches could achieve that objective more effectively.
Reddit has continued complying with the legislation while pursuing its legal challenge.
Digital Freedom Project Raises Concerns About Children’s Rights
The Digital Freedom Project has brought a separate challenge that is being considered alongside Reddit’s case.
The Sydney-based advocacy group argues that the legislation restricts political communication by preventing younger Australians from participating fully in online discussions.
Social media has become an important space for discussing elections, public policy, environmental issues and community concerns.
The group believes that excluding children from major online platforms can limit their opportunities to express opinions and engage with civic issues.
Its lawyers argue that the government could have adopted less restrictive measures to protect children.
These might include stronger platform safety requirements and improved protections against harmful content.
The challenge is based on Australia’s constitutionally implied freedom of political communication.
Unlike some countries, Australia does not have a general constitutional guarantee of freedom of speech.
Instead, the High Court has recognised an implied freedom that protects political communication necessary for Australia’s system of representative government.
The court must decide whether the legislation imposes an impermissible burden on that freedom.
Government Says Restrictions on Political Communication Are Limited
The Australian government disputes the argument that its legislation is unconstitutional.
Government lawyer Stephen Lloyd told the High Court that the restrictions impose only a limited and indirect burden on political communication.
The government argues that the legislation is designed to protect children rather than suppress particular political opinions.
It also maintains that young people can continue accessing some online information without holding social media accounts.
Under the legislation, children are not prohibited from using the internet generally.
They can still access many websites, educational resources and other online services.
Government lawyers say the restrictions target particular social media account features associated with potential harm.
The High Court will consider these arguments alongside the concerns raised by Reddit and the Digital Freedom Project.
How Many Social Media Accounts Have Been Removed?
The Australian government has reported that approximately five million social media accounts were closed or blocked following the introduction of the restrictions.
The figure was reported in government data published in July 2026.
However, the number of affected accounts does not necessarily represent five million individual children.
Some users may have held multiple accounts across different platforms.
The government has also acknowledged that the legislation has not prevented every under-16 user from accessing social media.
Some children have managed to bypass age-verification systems or continue using existing accounts.
These difficulties have raised questions about the effectiveness of the current approach.
Authorities are considering whether they need to take additional enforcement measures.
Can Children Still Access Social Media Despite the Ban?
Yes. Although the law prohibits covered platforms from allowing under-16s to maintain accounts, enforcement has proved challenging.
Some children have found ways around age-assurance systems.
Others can access publicly available content without signing into an account.
The legislation does not require social media companies to eliminate every possible instance of underage access.
Instead, platforms must take reasonable steps to comply with the law.
Determining what counts as reasonable compliance has become an important enforcement question.
Privacy is another challenge.
Australian authorities have restricted the use of compulsory government identification documents for age verification because of concerns about collecting sensitive personal information.
Technology companies must therefore balance age checks with user privacy and data protection.
Could Social Media Companies Face Heavy Fines?
Australia’s legislation allows substantial penalties for platforms that fail to meet their legal responsibilities.
Companies can face fines of up to A$49.5 million for certain breaches of the minimum-age requirements.
The government has also been considering stronger enforcement measures.
These penalties are intended to encourage technology companies to invest in age-assurance systems and comply with the restrictions.
However, the existence of penalties does not automatically establish that every underage account represents a punishable violation.
Regulators must assess whether a platform has taken the reasonable steps required by law.
That distinction will remain important as enforcement develops.
What Does the Social Media Ban Mean for Parents?
The legislation has generated considerable discussion among Australian parents.
Supporters believe that restricting social media accounts may help families manage online risks.
They argue that a nationwide minimum age can reduce pressure on parents to make difficult decisions individually.
Parents may also welcome measures designed to reduce exposure to harmful content, online bullying and excessive screen time.
However, critics warn that broad restrictions could remove access to valuable online communities.
Some teenagers use social media to maintain friendships, access educational information and participate in support networks.
Families may therefore have different experiences of the restrictions.
The debate highlights the challenge of balancing online safety with opportunities for communication and social connection.
Could the UK Introduce a Similar Social Media Ban?
Australia’s approach is being closely watched internationally.
Several countries have considered introducing minimum-age restrictions or stronger online safety rules for children.
The United Kingdom has also debated whether existing protections are sufficient.
The UK’s Online Safety Act already places duties on regulated online services to protect children from harmful content.
However, Australia’s approach goes further by imposing a minimum age for accounts on specified social media platforms.
A High Court ruling in Australia could influence discussions in Britain and elsewhere.
If the Australian legislation survives the constitutional challenge, supporters of similar measures may point to it as an example.
If the court finds constitutional problems, policymakers in other countries may examine how to design more targeted restrictions.
The Australian decision will not directly determine UK law, but it could shape international policy debates.
Why Is the High Court Decision Important?
The legal challenge raises questions that extend beyond Australia’s technology industry.
The court must consider the relationship between government regulation, child protection and political communication.
It must also assess whether the legislation is appropriately designed to achieve its stated purpose.
The government argues that the restrictions respond to genuine risks associated with social media platform design.
The challengers argue that the law places excessive limits on young people’s ability to communicate.
The High Court’s judgement could clarify how Australia’s implied freedom of political communication applies to digital platforms and younger users.
It may also influence the future of the country’s social media age-verification system.
When Will the Australian High Court Deliver Its Verdict?
The High Court completed its two-day hearing on Wednesday, 4 November 2026.
The judges have reserved their decision.
A final judgement is expected in the coming months, although no confirmed ruling date has been announced.
Until then, the existing legislation remains in force.
Covered social media companies must continue complying with their legal obligations.
The government has said it intends to defend the restrictions.
Reddit and the Digital Freedom Project are seeking a ruling that could change how the legislation operates.
Conclusion
The Australian social media ban for under 16s has become an important test of how governments can regulate digital platforms while respecting constitutional freedoms.
Australia argues that the restrictions are necessary to reduce risks to children’s mental health and wellbeing.
Reddit and the Digital Freedom Project maintain that the law is too broad and unnecessarily limits political communication.
Although millions of accounts have reportedly been removed or blocked, enforcement challenges remain.
The High Court’s eventual ruling could influence the future of Australia’s legislation and provide lessons for countries considering similar measures.
For now, the ban remains in effect as Australia awaits one of the most closely watched technology-related legal decisions of the year.
