In Australia, a lieutenant-governor is a standing appointment for a deputy governor of a state, who acts in place of the governor if the governor is unable, unavailable or unwilling to act.
Constitutionally, Australian state lieutenant-governors, administrators and chief justices of state supreme courts are normally separate offices.[1][2] However, in many states, such as New South Wales,[3] the Chief Justice of the Supreme Court is also the lieutenant-governor. In 2001, the Constitution of Queensland was amended to restore the office of lieutenant-governor in that state. When a state governor dies, resigns, or is absent, an administrator or acting governor is appointed. The state lieutenant-governors/administrators have no standing powers but stand ready to take up the governor's role.
In some states, there is also a standing deputy governor, who can exercise only the powers which the governor delegates to him or her.
