The nation's bold action to ban social platforms access for those under 16 is sending ripples internationally. Lawmakers, campaigners, and parents are watching intently to see if this strategy will set a precedent for countries abroad.
Across Europe, a increasing chorus of nations are considering similar restrictions.
At the EU level, the European parliament has adopted a symbolic motion demanding a ban for under-16s except if guardian approval is granted. Even though it cautions of the "habit-forming" design of these platforms, the step does not create mandatory rules.
"A strong age limit is a useful first step," stated the European lawmaker behind the resolution.
For the United Kingdom, the administration has remained open to a possible ban, arguing that "no measure is off the table" but stressing any policy must be "supported by conclusive research".
Earlier, momentum grew behind a legislative effort to enact controls on social media use by teenagers, but it was eventually watered down. Instead, the government committed to conduct more studies the matter.
Advocacy groups have raised concerns. An organization set up by the relatives of a young person who died after encountering disturbing platform posts suggests that a blanket age ban could fail to improve online safety and could result in a "sudden drop-off" of harm when users turn 16.
"This ban is a response to the refusal of the social media companies to build tools that are secure and fit for young users," said a leading child protection advocate.
Stateside, action is mostly unfolding at the regional level against a backdrop of country-wide inaction.
Even with bipartisan support and suggestions from some individuals to follow Australia's lead, a federal ban is right now seen as a distant prospect.
Apart from Europe and the US, further states are likewise taking action.
But, global agencies strike a more nuanced tone. The UN children's agency has warned that social media bans pose dangers and "could prove counterproductive". The organization notes that online platforms can be a "critical link" for marginalized young people and that regulation should not be a "substitute" for social media firms to improve safety.
While this worldwide debate unfolds, the actions of Australia and others indicate that governments globally are less and less willing to stand by for the industry to make changes on their own.
