ABSTRACT
The D-Notice system in Australia had its origins in the Cold War period immediately after the Second World War. This chapter summarizes the basic principles underlying the system. It is clear from the examination of the history of the D-Notice system that the subject matter of D-Notices is intended to be of the sort that relates to issues of national security. One of the major criticisms of the system is that it has been used for the wrong purposes. D-Notices might be used to cloak government ineptitude, or to hide other matters that have nothing to do with 'military' affairs, or to prevent government embarrassment, or even to prevent criticism of government policy. The D-Notice system works on voluntary agreement, so notionally at least the press has some choice as to what it publishes. While the interests of the general public may not be properly represented on the committee, the system may be seen as preferable to legal restrictions.
