Passage: The Australian Constitution dates from 1901, when the Dominions of the British Empire were not sovereign states, and does not use the term "head of state". As Australia is a constitutional monarchy, government and academic sources describe the Queen as head of state. In practice, the role of head of state of Australia is divided between two people, the Queen of Australia and the Governor-General of Australia, who is appointed by the Queen on the advice of the Prime Minister of Australia. Though in many respects the Governor-General is the Queen's representative, and exercises various constitutional powers in her name, they independently exercise many important powers in their own right. The governor-general represents Australia internationally, making and receiving state visits.
