The nation's bold action to ban social networking access for individuals under sixteen is sending ripples around the globe. Politicians, child protection groups, and families are observing closely to see if this strategy will inspire imitation for countries abroad.
In Europe, a rising group of nations are considering comparable measures.
Across the European Union, the bloc's legislature has approved a symbolic resolution supporting a ban for minors except if guardian approval is given. Even though it warns of the "addictive" design of these services, the step does not create binding law.
"A strong age barrier is a useful foundation," commented a leading European lawmaker supporting the initiative.
In the UK, the leadership has remained open to a future ban, stating that "nothing is off the table" but maintaining any decision must be "supported by strong data".
Last year, interest gathered behind a bill to enact controls on social media use by minors, but it was ultimately watered down. Instead, the government pledged to conduct more studies the topic.
Charities have expressed concerns. An organization set up by the loved ones of a young person who died after being exposed to harmful platform posts suggests that a simple age ban might not improve online safety and could result in a "cliff edge" of harm when young people turn 16.
"This ban is a response to the refusal of the tech sector to create tools that are appropriate and age appropriate for children," commented a influential online safety campaigner.
Across America, regulation is mostly happening at the regional level due to national stalemate.
Even with cross-party agreement and suggestions from some individuals to mimic Australia's path, a US-wide ban is currently seen as unlikely.
Apart from the West, further countries are likewise exploring options.
However, international agencies adopt a more nuanced stance. Unicef has cautioned that age-based restrictions have downsides and "might backfire". The agency highlights that online platforms can be a "critical link" for isolated children and that bans should not be a "replacement" for tech companies to invest in safety.
As this global discussion unfolds, the policies of the Australian government and others show that states around the world are less and less prepared to wait for the industry to make changes on their own.
