Australia has moved to strengthen its landmark social media restrictions for children by significantly increasing the financial penalties technology companies could face if they fail to prevent underage users from accessing their platforms.
The Australian government announced that it would double the maximum fines for companies found to be in breach of the country’s new online safety rules, reinforcing its determination to ensure social media platforms take greater responsibility for protecting children from harmful digital content.
The tougher enforcement measures form part of Australia’s broader strategy to implement one of the world’s strictest social media regulations for minors. The legislation, passed last year, prohibits children under the age of 16 from creating or maintaining accounts on designated social media platforms, placing the legal responsibility for compliance squarely on technology companies rather than parents or young users.
Under the revised framework, companies that fail to implement adequate age verification systems or knowingly allow underage users to remain on their platforms could face penalties of up to A$100 million, double the previous maximum sanction. The government believes the higher fines will encourage technology firms to invest more heavily in age assurance technologies and stronger online safety measures.
Australian authorities argue that existing safeguards have proven insufficient to protect children from harmful online experiences, including cyberbullying, exposure to violent or inappropriate content, online predators and addictive platform algorithms. Officials say the tougher penalties are intended to ensure that digital platforms treat child safety as a core legal obligation rather than a voluntary commitment.
The government has also released additional guidance outlining the expectations for technology companies before the law comes into full effect. Platforms will be required to demonstrate that they have taken reasonable and effective steps to prevent children under 16 from opening or operating accounts. Regulators will assess compliance based on the effectiveness of those systems rather than simply on company policies.
The legislation does not place criminal liability on children or their parents. Instead, enforcement will focus entirely on platform operators, with regulators empowered to investigate potential breaches and impose substantial financial sanctions where companies fail to meet their obligations.
Several major technology companies have expressed concerns about the practical implementation of the law. Industry representatives argue that reliable age verification remains technically challenging and warn that mandatory identity checks could raise privacy concerns for users. Companies have also questioned whether current technologies can accurately distinguish between users who are above or below the legal age threshold without collecting additional personal information.
Despite those concerns, Australian officials maintain that protecting children online outweighs the implementation challenges. The government says rapid advances in digital identity verification, artificial intelligence and age estimation technologies make it increasingly possible for platforms to verify users without unnecessarily compromising privacy.

Child welfare organisations and online safety advocates have broadly welcomed the tougher measures, arguing that social media companies have historically failed to act quickly enough to address the risks facing young users. Many have long called for stronger legal accountability, saying voluntary industry standards have not provided adequate protection.
Australia’s approach is being closely monitored by governments around the world as policymakers seek more effective ways to regulate large technology companies and improve online safety for minors. Several countries, including the United Kingdom, France and a number of U.S. states, are considering or implementing similar measures aimed at limiting children’s access to social media or strengthening age verification requirements.
The new penalties also reflect Australia’s increasingly assertive approach to regulating global technology firms. In recent years, the country has introduced a series of laws targeting digital platforms on issues ranging from misinformation and online safety to competition policy and payments for news content.
Technology companies operating in Australia will now be expected to demonstrate robust compliance frameworks before the new regime is fully enforced. This is likely to include stronger identity verification systems, enhanced parental controls, improved monitoring of user activity and regular reporting to regulators on measures taken to prevent underage access.
The government believes the strengthened enforcement framework will encourage platforms to prioritise child safety from the earliest stages of product design rather than responding only after harm has occurred. Officials have argued that creating a safer online environment for young people requires technology companies to accept greater responsibility for the services they provide.
As implementation of the new rules approaches, Australia is positioning itself at the forefront of global efforts to regulate children’s use of social media. The outcome of the legislation is expected to influence future digital safety policies internationally, particularly as governments continue to balance child protection, user privacy and technological innovation in an increasingly connected world.
