The nation's decisive policy to prohibit social platforms access for young people below 16 is sparking debate internationally. Lawmakers, child protection groups, and parents are observing intently to see if this tactic will become a template for other nations.
In Europe, a increasing group of countries are moving toward similar restrictions.
At the EU level, the EU parliament has passed a advisory motion demanding a ban for minors except if parental consent is provided. Even though it cautions of the "addictive" nature of these platforms, the resolution does not establish binding law.
"An effective age barrier is a good starting point," said the MEP driving the resolution.
In the UK, the government has not ruled out a future ban, arguing that "nothing is discarded" but stressing any decision must be "supported by strong research".
Earlier, interest grew behind a legislative effort to enact restrictions on social media use by teenagers, but it was in the end watered down. However, the administration committed to investigate the issue.
Advocacy groups have expressed concerns. An organization set up by the relatives of a teenager who took her own life after encountering dangerous social media material suggests that a simple age ban might not protect children and could result in a "cliff edge" of harm when users become eligible.
"The Australian ban is a response to the failure of the social media companies to build platforms and apps that are secure and suitable for young users," stated a influential peer.
In the United States, action is mostly occurring at the regional level against a backdrop of federal inaction.
Despite bipartisan support and proposals from certain figures to copy this example, a federal ban is presently seen as unlikely.
Beyond Europe and the US, other nations are also exploring options.
But, international bodies take a more nuanced stance. A major UN agency has cautioned that blanket prohibitions pose dangers and "could have unintended consequences". The agency notes that social networks can be a "vital connection" for vulnerable children and that government action should not be a "replacement" for tech companies to prioritize child safeguards.
While this worldwide discussion continues, the policies of this nation and several other countries indicate that policymakers internationally are less and less content to wait for tech companies to act voluntarily.
