 Australia has a common law understanding of "locus standi" or standing which is expressed in statutes such as the Administrative Decisions (Judicial Review) Act 1977 and common law decisions of the High Court of Australia especially the case "Australian Conservation Foundation v Commonwealth" (1980).At common law, the test for standing is whether the plaintiff has a "special interest in the subject matter of the action".Under the "Administrative Decisions (Judicial Review) Act" 1977 to have standing the applicant must be ‘a person who is aggrieved’, defined as ‘a person whose interests are adversely affected’ by the decision or conduct complained of.
