A NSW mother has won international support as Australia promoted its world-first social media age ban on a jam-packed final day at the United Nations.

Anthony Albanese is vying to build an international coalition to clamp down on children’s access to apps, such as Instagram, TikTok and Snapchat.

He was joined by parents who have campaigned for tougher social media laws at an event for world leaders in New York City.

They included NSW mum Emma Mason, whose daughter Tilly, 15, took her own life after being bullied on social media.

Ms Mason, who spoke in front of an image of Tilly, received a standing ovation at an event at the UN, which is hosting an annual meeting of world leaders.

The Bathurst resident said she was telling her story so other children didn’t have to endure the pain her daughter did.

“I’m so incredibly proud of Australia for leading the world and being the country that says we will no longer monetise our children,” she told reporters after her speech.

Mr Albanese described her address as “moving and powerful” and said it epitomised his discussions with other bereaved parents.

“If I, as Australian prime minister, could pluck out AOs (Orders of Australia) as I walk around … I would have walked up on stage here and given Emma one on the spot,” he said.

Australia will introduce social media age restrictions on December 10.

The incoming ban has faced backlash from social media companies, with Elon Musk’s X calling for it to be delayed over “serious concerns” about its lawfulness.

Communications Minister Anika Wells said she was meeting with tech giants while in the US to “eyeball them” and answer their questions about the laws.

“They will save lives,” she said in New York.

Europe is considering introducing similar laws to bar children under 16 from social media.

Australia’s age restrictions could also cause friction with the US, where many major online platforms are based.

The White House has raised concerns about other laws cracking down on tech giants’ use of Australian news content.

The issue could be discussed when Mr Albanese sits down with US President Donald Trump in Washington on October 20 after months of back-and-forth to secure a face-to-face meeting.

The Oval Office talks were announced after Mr Albanese briefly met the president at a reception for world leaders on Wednesday.

The pair posed for a selfie, which Mr Albanese posted on social media.

The prime minister described their interaction as a “very warm and engaging chat”.

“We look forward to a further discussion in a few weeks’ time,” he said.

The meeting in October will be significant but potentially risky, given the tongue-lashing other world leaders have received during White House talks, Australian Strategic Policy Institute Senior Fellow Mark Watson said.

“Anything other than abject humiliation would be a success,” he told AAP.

Mr Watson, who spent 33 years at the Department of Foreign Affairs and Trade, including a stint in Australia’s US embassy, said the prime minister would likely seek reassurances from Mr Trump on the AUKUS nuclear submarine deal.

The US is reviewing the three-country agreement, which includes the UK, to ensure it aligns with Mr Trump’s “America First” agenda.

This is the prime minister’s last full day in the US. He is due to meet his Sri Lankan counterpart and potentially sit down with Turkey’s strongman leader, Recep Tayyip Erdogan.

Earlier, speaking at another UN event, Mr Albanese promoted Australia’s new goal to reduce greenhouse gas emissions by 62 to 70 per cent on 2005 levels by 2035.

Australians know that extreme weather events are becoming more frequent and intense, the prime minister said, and the next decade would be decisive for action on climate change.

“An essential message that each of us can send to our citizens is this: it is not too late,” he said.
