4 The broad social purposes of censorship are, as I understand them, to ensure that ordinary members of the community are not affronted by the display of material to which a majority of reasonable adults would object, to maintain a level of public decency, and to avoid the undesirable social effects which may flow from the "normalisation", by its use in entertainment or other dissemination, of undesirable material. The extent to which regulation of this kind is desirable is, of course, a matter of political debate. By and large, the penalties provided for in the Act suggest that, while Parliament regards regulation of this kind as desirable, the possession and dissemination of material subject to the Act is not seen as among the more serious forms of social harm. So, for example, s 59, which deals with, inter alia, possession and display of indecent or obscene articles, provides a maximum penalty of $5000 for possession and a maximum of $10,000 for sale of such articles. Where the Act provides maximum penalties which include imprisonment, the terms are generally relatively short. For example, in s 68 the maximum penalty provided for exhibiting an unclassified film is $15,000 or imprisonment for 18 months.
