Anthony Albanese has already branded Australia's world-first teen social media ban a success while admitting its rollout "won't be perfect".
The ban takes effect on Wednesday - the deadline for social media platforms to restrict users aged between 13 and 15 from accessing their accounts.
The law applies to 10 platforms, including Facebook, Instagram, TikTok, Snapchat and X, and is aimed at protecting children from online harms.
Mr Albanese said the ban was a “success already” because it has sparked conversations about social media between parents and children.
“This is a change that hasn’t come from government," he told ABC's Insiders on Sunday.
"This is a change that has come from parents taking what is a personal tragedy and channelling that into wanting no other parents to go through the heartbreak they have experienced."
Labor has met repeatedly with parents including Emma Mason, the mother of 15-year-old Tilly, who took her own life after being bullied online.
Although the prime minister said the ban's rollout “won’t be perfect”, he compared it to liquor laws that prohibited anyone younger than 18 from buying alcohol.
"We've said very clearly that this won't be perfect, just like the chances are last night ... someone under 18 got a drink in a pub," he said.
"We want kids to have the opportunity to enjoy their childhood."
Communications Minister Anika Wells, who has come under fire for her $100,000 taxpayer-funded trip to New York to spruik the laws, warned the list of banned platforms could expand.
Ms Wells defended the trip in a gruelling 25-minute interview on Sunday, stating it was within government guidelines and had been "important to win allies" for the laws.
"We have had teens lose their lives and their parents bravely give up their own time to try and see reform around the world ... but we need allies for this to succeed," she told Sky News.
Several smaller apps are growing in popularity as children migrate to those not included in the ban.
They include Lemon8, which has agreed to restrict use of its app to those 16 and older as of Wednesday.
The coalition has ramped up its criticism of the ban, with Nationals leader David Littleproud unconvinced tech giants will comply.
"You've got to understand that these tech giants make a large portion of their advertising revenue from the fact that they have teenagers on their platforms," he told Sky News.
Platforms face up to $49.5 million in fines if they do not take "reasonable steps" to prevent under-16s from holding an account.
