Law enforcement in Australia is one of the three major components of the country's justice system, along with courts and corrections. Law enforcement officers are employed by all three levels of government – federal, state/territory, and local.

Federally, the primary law enforcement agency is the Australian Federal Police (AFP), which has a wide mandate to enforce Australian criminal law and protect its national interests. There is also a number of other agencies that have powers confined to specific areas, such as customs and immigration (Australian Border Force), and white-collar crime (Australian Taxation Office, Australian Competition & Consumer Commission, Australian Securities & Investments Commission). Each branch of the Australian Defence Force (ADF) has its own military police which operates under the Joint Military Police Unit (JMPU). The ADF Investigative Service also forms part of the JMPU and is the primary agency for complex investigations that fall under the Defence Force Discipline Act.

General law enforcement duties are generally the responsibility of state police forces, who are in turn responsible to a state government minister (usually a Minister for Police). These forces carry out uniformed policing throughout the entire state in which they operate. Other state government agencies may also have investigative or enforcement powers for specific offences within their purview, such as fisheries. The Northern Territory is the only Australian Territory with its own police force, but in Australia's other territories (including the Australian Capital Territory) law enforcement is handled by the Federal Government, specifically the Australian Federal Police. Local governments may also employ their authorised officers, commonly known as council rangers, to enforce local government by-laws or certain state laws pertaining solely to the local government jurisdiction in which they're employed. Council rangers do not have full police powers unless they are sworn as special constables.

State police officers and Australian Federal Police officers routinely carry firearms, other state and federal law enforcement officers may carry firearms or other items for personal defence depending on their agency or the condition in which they're deployed. While on duty, an armed law enforcement officer's duty belt generally consists of a handgun, Taser, expandable baton, pepper spray, a set of handcuffs, ammunition magazines, gloves, torch, and a two-way radio.
