Newspapers across Australia ran heavily redacted front pages on Monday in protest against government secrecy and a crackdown on press freedom, a rare show of unity in a fractious media landscape.

National and regional mastheads including The Australian, The Sydney Morning Herald and the Australian Financial Review hit newsstands Monday with most of their front-page news stories blacked out.

Advertisements have also been rolled out across the country’s television networks, asking viewers to consider the question: “When the government hides the truth from you, what are they covering up?”

The campaign by the Right to Know coalition was sparked by federal police raids on the national broadcaster ABC and a News Corp journalist’s home earlier this year over two stories that had proved embarrassing for the government.

It centres on six demands, including exemptions for journalists from strict national security laws that have created a complex web of provisions critics say too easily ensnare reporters doing their jobs.

“The culture of secrecy that has descended through these legal provisions restricts every Australian’s right to know and goes well beyond the original intent of national security,” Media Entertainment and Arts Alliance union head Paul Murphy said.
