Australia's Communications Minister Anika Wells has told the BBC she is not intimidated by technology companies who disagree with the country's "world-leading" social media ban and is ready if Washington weighs in.

From December 10, ten social media firms including Snapchat, Meta, TikTok and YouTube will have to take what the government says are "reasonable steps" to stop children under 16 from having accounts on their platforms.

"We stand firm on the side of parents and not on the platforms," Wells said.

Companies including Meta have said they agree more is needed to keep young people safe online, but don't think a ban is the answer, with some experts raising similar concerns.

Speaking to the BBC in Brisbane, Wells said the tech companies have had plenty of time - 15 to 20 years - to improve their practices, in light of research indicating their platforms cause harm.
