Criminal law in Australia governs how individuals are investigated, charged, and prosecuted for offences ranging from traffic infringements to serious criminal acts. While the underlying legal principles are similar nationwide, each state and territory has its own legislation, court structures, and procedures.
This guide outlines criminal law in Australia and provides state-specific overviews so you can understand the legal system where you live or where an offence has occurred.
Criminal law deals with offences against the community, the state, or a person. These laws are enforced by the police and prosecuted by the state. A criminal case usually begins with a police investigation and can end with a fine, community order, or imprisonment if a person is found guilty.
Investigation – Police gather evidence and may question suspects.
Charge – A person may be charged with an offence or issued a court attendance notice.
Bail – A decision is made about whether the accused remains in custody.
Court Proceedings – The matter is heard in court. The accused can plead guilty or not guilty.
Hearing or Trial – Evidence is presented before a judge, magistrate, or jury.
Sentencing – If guilty, a penalty is imposed based on the seriousness of the offence.
Appeal – The accused may appeal the conviction or sentence in higher courts.
