5.1 This chapter introduces the ALRC’s proposed new National Classification Scheme. The chapter briefly summarises the overall rationale for the establishment of the proposed new scheme, highlighting its key benefits and how the scheme responds to the guiding principles of reform identified in Chapter 4, as well as the current problems and future challenges discussed in Chapters 2 and 3. The chapter presents centrepiece proposals establishing the new scheme, through the enactment of a new Classification of Media Content Act. Under the Act, a single agency (the Regulator) would be responsible for regulating the classification of media content. The proposed content of the new Act, and the functions and responsibilities of the Regulator, are discussed in more detail throughout this Discussion Paper.
