Australia on Friday called for governments around the world to agree on "rules of the road" to fight the spread of misinformation and state-backed disinformation online. Foreign Minister Marise Payne said blocs like the Quad group - the United States, India, Japan and Australia - and global bodies like the United Nations were already working to strike a balance between harmful content and free expression online. But time was running out to agree on rules of what was permissable. "We should be starting yesterday," Payne told a panel at the Sydney Dialogue virtual event alongside Facebook Inc's global affairs boss.
