The nation's decisive action to restrict social networking access for individuals under sixteen is creating waves worldwide. Politicians, campaigners, and families are watching intently to see if this tactic will become a template for countries abroad.
Across Europe, a rising number of countries are moving toward similar measures.
Across the European Union, the European parliament has passed a non-binding motion supporting a ban for minors unless parental consent is provided. Although it cautions of the "compulsive" design of these platforms, the resolution does not establish binding law.
"An effective age barrier is a good first step," said one parliamentarian supporting the resolution.
For the United Kingdom, the leadership has kept open a possible ban, stating that "no option is off the table" but maintaining any action must be "grounded in robust research".
Earlier, support grew behind a proposal to introduce controls on social media use by minors, but it was ultimately modified. However, the government committed to further research the topic.
Advocacy groups have raised apprehensions. A prominent charity set up by the loved ones of a teenager who was lost after viewing harmful online content suggests that a simple age ban could fail to improve online safety and could result in a "cliff edge" of harm when teens turn 16.
"The Australian ban is a answer to the refusal of the tech sector to design platforms and apps that are appropriate and suitable for young users," stated a leading peer.
In the United States, legislation is largely unfolding at the local government level against a backdrop of national inaction.
Despite cross-party agreement and proposals from certain figures to mimic Australia's example, a nationwide ban is currently seen as unlikely.
Apart from the West, other countries are likewise taking action.
Yet, international bodies strike a more measured tone. The UN children's agency has advised that blanket prohibitions pose dangers and "could have unintended consequences". The body highlights that social networks can be a "critical link" for marginalized youth and that government action should not be a "replacement" for platform operators to improve user protection.
As this global discussion evolves, the steps of this nation and others demonstrate that policymakers internationally are less and less content to delay for platforms to make changes on their own.
