Australian Citizenship Practice Exam

Australia's head of state is the Queen of Australia, Her Majesty Queen Elizabeth 2nd. She holds a ceremonial role and is represented by the Governor General in Australia's government. The Prime Minister is the head of government, not the head of state. The Chief Justice is the head of the judicial branch, not the head of state. Therefore, options A, B, and C are incorrect. The Queen of Australia, being a constitutional monarch, is considered to be the ultimate authority and head of state in Australia.
