The Premiers of the Australian states are the de facto heads of the executive governments in the six states of the Commonwealth of Australia. They perform the same function at the state level as the Prime Minister of Australia performs at the national level. The territory equivalents to the Premiers are the Chief Ministers of the Northern Territory and the Australian Capital Territory. The Queen of Australia and the State Governors are the formal repositories of executive power, however, in practice they act only on the advice of State Premiers and Ministers.
