The nation's decisive action to prohibit social networking access for young people below 16 is creating waves internationally. Lawmakers, campaigners, and parents are watching with great interest to see if this strategy will set a precedent for other nations.
Throughout Europe, a growing chorus of states are exploring comparable restrictions.
For the broader EU, the European parliament has approved a symbolic statement calling for a ban for teenagers under 16 unless guardian approval is provided. Even though it highlights of the "addictive" design of these platforms, the step does not establish binding law.
"A clear age barrier is a solid first step," said the parliamentarian driving the measure.
In the UK, the leadership has not ruled out a future ban, arguing that "no option is discarded" but stressing any action must be "grounded in conclusive research".
Earlier, support grew behind a legislative effort to enact controls on social media use by minors, but it was eventually watered down. Instead, the government pledged to further research the issue.
Charities have voiced warnings. One foundation set up by the relatives of a girl who took her own life after viewing disturbing online content argues that a simple age ban might not protect children and could lead to a "cliff edge" of risk when young people reach the legal age.
"This ban is a response to the inability of the social media companies to build tools that are secure and age appropriate for children," said a influential child protection advocate.
Across America, action is largely occurring at the local level against a backdrop of federal inaction.
Despite cross-party agreement and proposals from certain figures to follow the Australian lead, a US-wide ban is right now seen as unlikely.
Outside of the West, additional nations are similarly taking action.
But, world bodies strike a more measured position. Unicef has warned that age-based restrictions carry risks and "might prove counterproductive". The organization notes that the internet can be a "lifeline" for isolated children and that government action should not be a "excuse" for social media firms to invest in child safeguards.
Even as this international conversation continues, the policies of Australia and several other countries show that policymakers globally are no longer willing to wait for platforms to make changes on their own.
