Australia's social media age ban: A digital turning point for society and investment markets

In a global first and a warning shot for platforms, at the end of 2025 Australia became the first country to ban under-16s from social media, with penalties of up to $49.5 million for platforms that fail to comply.

Where Australia has led, the world is following. The regulatory wave is spreading fast, with countries such as Malaysia, Singapore, Japan, France and the UK following suit, and a potential 83 million children across Asia Pacific (APAC) and Europe impacted.

These restrictions mark a significant response to mounting evidence that social media is contributing to rising levels of anxiety, depression and other mental health challenges among young people.

How companies respond to these new societal and legislative shifts will be key. It is clear that for companies, the risk of digital harm is evolving from a reputational risk to a financially material one - as a result, strong corporate governance will be increasingly important as they seek to navigate this change.

The catalyst for change

A growing body of research around the world has examined the youth mental health crisis and its links to smartphones and social media (Exhibit 1). Australia's National Mental Health Commission has found that "half of all adult mental health challenges emerge before the age of 14".

An important theme behind Australia's pioneering legislation is that it places the burden of compliance firmly with the platform and not the user. Measures intended to restrict platform usage among Australia's under-16s include requiring platforms to deactivate and remove existing accounts, introduce ID-based age verification, and prevent workarounds through the use of virtual private networks (VPNs).

A key intention of the legislation is to reduce the negative impact of social media's features intended to maximise user engagement, such as "infinite scroll" and "autoplay." By doing so, policymakers are hoping that young people will be empowered to build their community and identity offline, reclaiming a more traditional, play-based childhood.

If the ban works as intended, the societal benefits could be substantial: improved health as a result of increased physical activity, stronger communities built on face-to-face interaction, and longer-term productivity gains due to improved sleep, mental resilience, and reduced burnout.

The story so far and danger of unintended consequences

In the few days following the law coming into force, 4.7 million accounts were reportedly closed across in-scope platforms. Given that children aged 8-15 account for approximately 5%, or 2.6 million, of Australia's population, this suggests many young users held multiple

accounts across different platforms. Tempering that success, however, other data point to more mixed results, while media reports have also highlighted gaps in age-verification enforcement protocols.

Despite these initial stumbling blocks, there are signs of behavioural shifts: social media usage has declined since the ban, while gaming composites have seen user growth

indicating a displacement rather than a reduction in young people's screen time.

Australia's early experience highlights a more fundamental challenge: the societal experience of social media is not universally negative. While platforms can expose young people to harmful content, those same platforms can also provide crucial resources and support networks for vulnerable populations.

Indeed, a recent research report shows that 73% of young people across Australia accessing mental health support did so through social media. Furthermore, organisations including the Australian Human Rights Commission argue that social media restrictions could curb a "right to freedom and cause isolation, limiting access to information and support", particularly crucial for vulnerable or remote communities.

The impacts of this ban, then, could be widespread, with social media playing a role in education, job searches, and social mobility. Mindful of the "law of unintended consequences", such well-intended restrictions in Australia and elsewhere could contribute to a significant digital divide between population groups with and without such access.

Approaches may differ, but the direction of travel looks clear, with governments in aggregate moving toward stricter regulation of young people's access to social media platforms. As a measure of the potential scale of this change, if we were to see a rollout of social media

bans across APAC and European markets, an estimated 83 million children aged 10 to 14 - around 12% of the global cohort - could be affected

Implications for investors

For equity investors, a societal policy shift of this magnitude presents some near- to medium-term risks, as well as a number of strategic opportunities across multiple sectors. In particular, convergence in regulatory frameworks across countries and regions could accelerate the financial impact on affected companies.

Compliance costs could rise as platforms are required to invest in age verification, trust and safety, and content moderation infrastructure. For advertising, the impacts are likely to be more nuanced - ranging from changes in user acquisition and channel strategy among younger demographics, to a shift in social media engagement over the medium term.

However, while there are risks, there are opportunities as well. As young people shift from social media to other media channels, this could favour more traditional, often local media outlets, such as television and radio.

Elsewhere, gaming platforms, currently exempt from age-based restrictions, could see an uplift if youth migrate from social media to gaming Furthermore, social media legislation highlights opportunities for global, scalable, and privacy-preserving digital identity and verification software.

For investors, an active approach is essential to monitoring these developments and identifying those businesses that can successfully adapt to a new legislative and business environment. Companies with strong transparency, particularly in areas such as AI use, as well as robust board oversight and well-aligned incentives, are likely to be better positioned.
