What type of leader does Australia have?

Australia is a constitutional monarchy with a parliamentary government at the federal level. The head of state is the King of Australia, who is represented in Australia by a governor-general. The governor-general acts on the advice of the prime minister, who is the head of government and leader of the country. The prime minister is appointed by the governor-general based on his or her ability to command the support of the majority of the members of the House of Representatives, the lower house of the Australian Parliament.

Australia also has state and territory governments, each of which has its own premier or chief minister as the head of government.
