Millions of Australian children could be barred from using social media platforms under age-limit changes floated by state premiers who want bolstered protections for young people against online harm.

The leaders of NSW, Queensland and Victoria united on Monday in a push to lift age minimums on major operators such as the Meta-owned Facebook and Instagram, and TikTok.

All of the platforms require users to be at least 13 years old, but that limit could be lifted to as high as 16 under a proposal from NSW.

South Australia is investigating if it can impose social-media bans for children aged under 14 and parental permission for those aged under 16 amid rising concern over harms of social media content on minors.

A police officer stabbed in a daylight attack in Sydney's city centre displayed "enormous courage" in chasing after his assailant in spite of his injuries, the NSW premier says.

Elvis Poa, 35, remains in a stable condition in hospital after being stabbed near Hyde Park early on Sunday afternoon.

He and another officer were performing traffic duties just after 1pm on the corner of Castlereagh and Park streets when they were approached by the 35-year-old alleged attacker.

The man allegedly produced a 30cm long "kitchen-style" knife and stabbed Constable Poa in the back of the head two to three times.

He fled and was pursued by the injured officer and a female constable along Park St and into Hyde Park, where officers directed him to drop the knife.

Other officers arrived and the man was tasered before being taken into custody, police said.

"The officer involved showed enormous courage," Premier Chris Minns told reporters.

"To not only be the victim of an alleged assault, but also to apprehend the person who is alleged to have committed the offence."

How's this for a bit of luck.

A Canberra man has scooped $2.5 million on the Saturday Lotto with his first ever lottery ticket.

"I just bought this ticket on the spur of the moment. I’ve never bought a lottery ticket before," he told officials.

“Then, on Sunday morning, I woke up and saw I had this ticket in my wallet, so I thought I’d check it.

“Oh sh**! I can’t explain the moment. I just can’t believe it."

Well this is an unfortunate turn of events for Donald Trump.

Repeatedly calling out President Joe Biden for his supposed unsuitability to lead the country at 81, Trump, 77, has had his own moment to forget while addressing those gathered at the National Rifle Association’s annual meeting.

The former president appeared to freeze for more than 30 seconds, much to the joy of Biden's supporters. Unsurprisingly Trump's faithful offered their explanations, suggesting the teleprompter was down or he was just listening.
