Australia’s constitutions tell only part of the story. They omit or barely mention many of the essential and well-known elements of the system of government, such as the cabinet, the prime minister or premier, ministerial responsibility or the opposition. This work fills that void by explaining the nature of conventions, how they arise, how they are altered, as well as their operation and development. This is a book for anyone who has an interest in understanding the complexities and mysteries of the unwritten rules of Australian systems of government.
