Australia is a constitutional monarchy. This means that the head of State is a monarch, who is governed and bound by the Constitution.
Whilst the Constitution gives the monarch and the Governor-General extensive powers, the modern British monarchy is above politics and does not exercise political power. This power resides in the Parliament.
Our political system has evolved into a liberal democracy in which Parliament and the Executive share power and the monarch acts on the advice of the government of the day. This is regarded as appropriate because both, monarch and governor are unelected.
