MacArthur formed his own signals intelligence organization, known as the Central Bureau, from Australian intelligence units and American cryptanalysts who had escaped from the Philippines. This unit forwarded Ultra information to MacArthur's Chief of Intelligence, Charles A. Willoughby, for analysis. After a press release revealed details of the Japanese naval dispositions during the Battle of the Coral Sea, at which a Japanese attempt to capture Port Moresby was turned back, Roosevelt ordered that censorship be imposed in Australia, and the Advisory War Council granted GHQ censorship authority over the Australian press. Australian newspapers were restricted to what was reported in the daily GHQ communiqué. Veteran correspondents considered the communiqués, which MacArthur drafted personally, "a total farce" and "Alice-in-Wonderland information handed out at high level".
