Several terms used throughout the ND Act serve to delineate its scope and operating principles. Some terms are defined in the ND Act, while others are not. Some definitions adopt or refer to definitions in the Single Convention.
The Discussion Paper invited comment on whether key terms are appropriately defined in the ND Act, having regard to Australia's obligation to adhere to the requirements of the Single Convention. The submissions drew attention to ambiguity or inconvenience in some definitions. Some definitional questions will be answered if the licensing and permit regime is restructured as recommended in Chapter 6, but other issues may warrant amendment of a definition in the ND Act or the publication by the ODC of extended guidance on the meaning of key terms in the ND Act.
