The Australian Constitution was written in 1901, when the Dominions of the British Empire were not independent countries, and does not use the words "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. The Governor- General 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 are also independently vested with many important constitutional powers by the Constitution.
