Australia has introduced a landmark digital safety law that will prohibit children under the age of 16 from accessing major social media platforms starting December 2025. The legislation targets popular platforms such as TikTok, Instagram, and YouTube, placing the responsibility squarely on technology companies to prevent underage access. Platforms that fail to comply could face substantial financial penalties, marking one of the toughest regulatory approaches to social media use by minors anywhere in the world.

The government says the move is designed to protect young people from algorithm-driven content that can amplify anxiety, depression, and other mental health challenges. Lawmakers argue that recommendation systems often push harmful or addictive material, exposing children to unrealistic standards, cyberbullying, and excessive screen time at a formative stage of development. By restricting access, authorities hope to reduce these risks and encourage healthier online habits among teenagers.

However, the law has sparked intense debate across Australia. Critics warn that enforcing age restrictions at scale will be technically difficult and could raise concerns around privacy, as platforms may require stronger age-verification mechanisms. Others argue that a blanket ban could limit free expression, digital literacy, and access to educational or creative content that young users benefit from. There are also questions about how the law will affect children who already rely on social platforms for social connection and support.

Internationally, the legislation is being closely watched. Several countries grappling with the impact of social media on youth mental health are considering similar measures, and Australia’s approach may serve as a global test case. Whether the ban successfully balances child protection, personal freedoms, and practical enforcement will likely shape future digital policy debates worldwide.
