“The truth of the matter is that unless you have consciously set those posts to private since 2007, Meta has just decided that [it] will scrape all of the photos and all of the texts from every public post on Instagram or Facebook since 2007, unless there was a conscious decision to set them on private. That’s the reality, isn’t it?,” Shoebridge asked.

“Correct,” Claybaugh responded.

Australia is weighing how best to regulate AI technologies, and Sheldon said after the hearing that the nation’s privacy laws may need an overhaul in response to the revelations. The federal government has flagged an update to the Privacy Act, but those changes have been delayed multiple times and are yet to be introduced to the parliament.

“Meta must think we’re mugs if they expect us to believe someone uploading a family photo to Facebook in 2007 consented to it being used 17 years later to train AI technology that didn’t even exist at the time,” Sheldon said.

“The personal moments people share - photos, videos, and records of people’s lives, their children, and their families - are not fodder for a tech company to turn into new products. It’s an unprecedented violation of what makes us human.

“It’s not just dishonest, it’s predatory. And if our privacy laws allow this, they need to be changed.”

Independent senator David Pocock also said that new privacy laws are needed.

“A clear takeaway from Meta’s testimony this morning is that we urgently need strong privacy legislation, like the European Union, to force these social media giants to do the right thing by our communities in Australia,” he said.

“I’m also really concerned about the total lack of transparency around social media algorithms and the harm they are doing, especially to young people.”

Meta has been hit with complaints in 11 countries over its data collection practices, but says it’s simply following the same approach as other AI firms such as Google and OpenAI.

A Meta spokeswoman previously said that the company was “committed to building AI responsibly”.

“With the release of our AI experiences, we’ve shared details about the kinds of information we use to build and improve AI experiences – which includes public posts from Instagram and Facebook – consistent with our privacy policy and terms of service,” the spokeswoman said.

“While we don’t currently have an opt-out feature, we’ve built in-platform tools that allow people to delete their personal information from chats with Meta AI across our apps. Depending on where people live, they can also object to the use of their personal information ... to build and train AI consistent with local privacy laws.”

Meta also defended a response by its chatbot that described Hamas as a Muslim “armed resistance” movement, but did not mention its October 7 massacres in Israel.

Meta’s regional public policy boss, Simon Milner, said he had not seen the response that opposition senator James McGrath read out in parliament, but viewed it as a “factual response”.

“You may have gone on to ask it more questions about the atrocities of October 7 last year and I would be interested to see how that played out,” Milner told the parliamentary inquiry.

Milner said Meta’s AI tool was learning and improving over time.

“The AI learns from feedback when people feel that there are issues around political bias, and we’re always looking to improve it,” Milner said.

The Senate committee into AI adoption is set to report to parliament before September 19.
