TheCopyright Act1968 (Cth)protects two distinct categories of subject matter - 'Works' (literary works (textual material), dramatic works, musical works and artistic works), and 'subject matter other than works' (sound recordings, films, television and sound broadcasts and published editions). How useful is this distinction in providing effective and equitable copyright protection?Is there an alternative approach to describing subject matter that you think might be more effective and equitable? Discuss with reference to relevant legislation, case law and/or scholarly materials.
