Australia has no constitutional protection for the right to silence, but it is broadly recognized by State and Federal Crimes Acts and Codes and is regarded by the courts as an important common law right and a part of the privilege against self-incrimination. In general, criminal suspects in Australia have the right to refuse to answer questions posed to them by police before trial and to refuse to give evidence at trial. However a person must provide their full name, address, place of birth, and date of birth if asked to by police. No other question has to be answered. As a general rule judges cannot direct juries to draw adverse inferences from a defendant's silence ("Petty v R") but there are exceptions to this rule, most notably in cases which rely entirely on circumstantial evidence which it is only possible for the defendant to testify about ("Weissensteiner v R"). This exception has been abolished in Victoria by sections 42 and 44 of the "Jury Directions Act 2015". The right does not apply to corporations ("EPA v Caltex").
