Facebook has threatened to block users and publishers in Australia from sharing news on its platform if the country presses ahead with a landmark proposal to force big tech to pay media groups for carrying their content.

The US social media platform said it would “reluctantly stop allowing publishers and people in Australia from sharing local and international news on Facebook and Instagram” if the draft legislation comes into force.

“This is not our first choice—it is our last. But it is the only way to protect against an outcome that defies logic and will hurt, not help, the long-term vibrancy of Australia’s news and media sector,” Facebook said in a statement.
