The nation's controversial policy to restrict social networking access for young people below 16 is creating waves internationally. Officials, campaigners, and families are watching with great interest to see if this approach will set a precedent for countries abroad.
In Europe, a growing group of countries are moving toward similar measures.
At the EU level, the European parliament has approved a symbolic statement supporting a ban for teenagers under 16 unless guardian approval is granted. Even though it highlights of the "compulsive" quality of these services, the move does not enact binding law.
"An effective age barrier is a good starting point," stated a leading European lawmaker behind the measure.
Across Britain, the leadership has remained open to a possible ban, emphasizing that "no measure is being dismissed" but insisting any policy must be "supported by robust evidence".
Earlier, momentum gathered behind a legislative effort to introduce limits on social media use by teenagers, but it was eventually modified. However, the government pledged to conduct more studies the issue.
Campaign organizations have voiced apprehensions. One foundation set up by the family of a teenager who died after encountering disturbing social media material argues that a blanket age ban may not improve online safety and could result in a "sudden drop-off" of exposure when users reach the legal age.
"The Australian ban is a answer to the inability of the social media companies to build tools that are secure and fit for children," commented a influential peer.
Stateside, legislation is primarily unfolding at the regional level against a backdrop of national stalemate.
Even with cross-party agreement and calls from some individuals to follow the Australian example, a nationwide ban is right now seen as improbable.
Apart from these regions, additional countries are also considering moves.
However, international organizations strike a more nuanced tone. The UN children's agency has cautioned that age-based restrictions have downsides and "could have unintended consequences". The agency points out that the internet can be a "critical link" for isolated young people and that bans should not be a "excuse" for platform operators to prioritize child safeguards.
While this global debate unfolds, the actions of this nation and its followers demonstrate that states around the world are no longer willing to wait for platforms to self-regulate.
