The nation's controversial action to restrict social platforms access for young people below 16 is creating waves around the globe. Lawmakers, campaigners, and guardians are watching with great interest to see if this tactic will set a precedent for countries abroad.
In Europe, a rising group of countries are considering similar measures.
For the broader EU, the European parliament has adopted a advisory statement demanding a ban for teenagers under 16 unless parental consent is granted. Although it highlights of the "addictive" nature of these platforms, the resolution does not enact mandatory rules.
"A strong age limit is a useful foundation," said one parliamentarian driving the initiative.
Across Britain, the administration has kept open a future ban, stating that "nothing is discarded" but maintaining any action must be "supported by strong research".
Previously, momentum grew behind a bill to introduce controls on social media use by minors, but it was eventually weakened. Nonetheless, the government committed to investigate the issue.
Campaign organizations have expressed concerns. One foundation set up by the loved ones of a teenager who was lost after viewing dangerous online content contends that a blanket age ban could fail to improve online safety and could result in a "sudden drop-off" of harm when young people reach the legal age.
"This ban is a reaction to the failure of the tech sector to create platforms and apps that are safe and age appropriate for young users," commented a prominent peer.
Across America, legislation is largely occurring at the local government level amid federal stalemate.
Even with widespread concern and suggestions from some individuals to copy Australia's lead, a US-wide ban is right now seen as a distant prospect.
Outside of the West, additional nations are also exploring options.
But, international bodies take a more cautious tone. The UN children's agency has warned that blanket prohibitions have downsides and "may even backfire". The body notes that online platforms can be a "lifeline" for vulnerable youth and that government action should not be a "substitute" for social media firms to invest in safety.
While this worldwide debate evolves, the policies of the Australian government and its followers indicate that policymakers globally are less and less willing to delay for tech companies to self-regulate.
