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. However, in many states, such as New South Wales, 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, wolLieutenant-governor". 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.
In New South Wales, there is a lieutenant-governor and an administrator, who takes up the duties of the Governor if the governor dies, resigns, or is absent.
Since 1872 the office was permanently filled by the Chief Justice of New South Wales but the position may be retained by the chief justice after his/her retirement from the Supreme Court of New South Wales.
If the lieutenant-governor becomes incapacitated while serving in the office of governor, the next most senior judge of the Supreme Court is sworn in as administrator.
The lieutenant-governors/administrators have no standing powers but stand ready to act in the governor's position.
Tom Bathurst, Chief Justice of the Supreme Court of New South Wales, is the current lieutenant governor.
In South Australia, the lieutenant governor is appointed by the Governor at the governor's pleasure. The lieutenant governor acts as the vice-regal representative in the governor's absence.
