Australian administrative law defines the extent of the powers and responsibilities held by administrative agencies of Australian governments. It is basically a common law system, with an increasing statutory overlay that has shifted its focus toward codified judicial review and to tribunals with extensive jurisdiction.
Australia possesses well-developed ombudsman systems and Freedom of Information legislation, both influenced by comparable overseas developments. Its notice and comment requirements for the making of delegated legislation have parallels to the United States. Australia's borrowings from overseas are still largely shaped by its evolution within a system of parliamentary democracy that loosely follows a Westminster system of responsibility and accountability. At the same time, its application has been limited by a shift toward deregulation and privatisation.
The constitutional framework and development of administrative law in Australia was highly influenced by legal developments in the United Kingdom and United States. At the end of the 19th century, the British constitutional theorist A. V. Dicey argued that there should be no separate system of administrative law such as the droit administratif which existed in France. As a result, Australian administrative law before World War II developed in an unplanned way.
The present administrative law is largely a result of growing concern about control of bureaucratic decisions in the 1960s. In response a set of committees were established in the early 1970s, whose recommendations constituted the basis for what became known as the "New Administrative Law". The most important of these, the Kerr Report, recommended the establishment of a general administrative tribunal which could review administrative decisions on the merits, codification and procedural reform of the system of judicial review, and the creation of an office of Ombudsman. These proposals were put into practice with the passing of a package of federal statutes: the Administrative Appeals Tribunal Act 1975, the Ombudsman Act 1976, the Administrative Decisions (Judicial Review) Act 1977, and the Freedom of Information Act 1982. Some of those have since been replicated in states and territories.
