In the name of national security: press censorship in Cold War Australia

Though little known, a system of voluntary press censorship based on the British D Notice system operated in Australia during the Cold War. The Australian D Notice system, while successful in the early decades of the Cold War, became increasingly contested throughout the 1970s before apparently falling into disuse in the 1980s. The belief that Australia’s D Notice system simply decayed through lack of use is generally accepted by scholars; however, this explanation does not sufficiently convey the complexity behind the breakdown of the system. The system relies heavily on trust and requires a degree of transparency between governments and the press. This article makes the case that a broadening of the definition of national security combined with the simultaneous growth of both investigative journalism and the perception of increased government secrecy was the ultimate cause of the failure of the D Notice system in Australia.
