The purpose of this article is to examine Australia's regulatory system for the classification of publications, films and computer games, the National Classification System (‘NCS’), and to question whether its classification decision process is susceptible to political influence. Formed in 1995 as a cooperative scheme between the Commonwealth, States and Territories, the NCS was created to overcome problems associated with former classification schemes that operated on a non-national basis in each Australian jurisdiction. It is argued that, although the current system is superior to the ones of the past, it still allows, or at least perceivably allows, political influence in censorship decision-making, as was historically the case. This is because documents used by the Classification Board and Classification Review Board (‘the Boards’) to make classification decisions are ambiguous and often inconsistent, and, even with redrafting, would remain so without the benefit of judicial precedent. The ambiguity created by the classification documents legitimates the possible exercise of political influence through a variety of means.
