In less than three years the federal government intervened at least 4213 times to restrict or censor posts about the Covid-19 pandemic on digital platforms. A freedom of information request by Liberal senator Alex Antic has revealed the number of interventions, but details about the reasons or the guidelines under which they were made remain secret. It is entirely unclear to me why the Department of Home Affairs, a department which is primarily charged with the duty of overseeing matters like border control, has been using a backdoor arrangement with social media companies to influence the media in relation into matters such as public health," Senator Antic said. Senator Antic ... is now in possession of the Department of Home Affairs Online Content Incident Arrangement Procedural Guideline, which details how the government works with digital platforms such as Facebook, Meta, Twitter, Instagram and Google to monitor and intervene on content. The document is subheaded "Australia's domestic crisis response protocol for online terrorist and extreme violent content". It runs to 28 pages but aside from the title, every page has been fully redacted. A separate document ... revealed that between January 2017 and December 2022 it "had made 13,636 referrals to digital platforms to review content". More than 9000 of these were related to terrorism and violent extremism. But 4213 were "Covid-19-related referrals".
