The nation's bold move to restrict social platforms access for young people below 16 is creating waves around the globe. Lawmakers, safety advocates, and parents are monitoring closely to see if this tactic will become a template for the rest of the world.
In Europe, a growing group of countries are considering similar bans.
At the EU level, the bloc's legislature has passed a symbolic resolution demanding a ban for under-16s without parental consent is granted. Although it highlights of the "addictive" design of these services, the move does not create mandatory rules.
"A clear age barrier is a good first step," commented the European lawmaker behind the initiative.
Across Britain, the administration has remained open to a possible ban, stating that "nothing is being dismissed" but maintaining any action must be "based on robust evidence".
Last year, momentum grew behind a bill to enact controls on social media use by minors, but it was ultimately modified. Instead, the administration committed to further research the topic.
Advocacy groups have voiced concerns. An organization established by the relatives of a young person who died after encountering disturbing online content argues that a strict age ban could fail to protect children and could lead to a "dangerous transition" of exposure when young people turn 16.
"Australia's ban is a response to the refusal of the social media companies to create products and services that are secure and fit for young users," commented a prominent online safety campaigner.
Stateside, action is mostly happening at the state level amid country-wide gridlock.
Despite widespread concern and suggestions from certain figures to follow the Australian lead, a federal ban is currently seen as unlikely.
Beyond these regions, further states are likewise considering moves.
Yet, world bodies adopt a more cautious tone. The UN children's agency has cautioned that social media bans pose dangers and "might prove counterproductive". The agency notes that social networks can be a "vital connection" for vulnerable youth and that bans should not be a "substitute" for platform operators to improve user protection.
As this global discussion continues, the actions of this nation and others show that policymakers globally are increasingly content to wait for the industry to act voluntarily.
