The Prime Minister of Australia is the head of government of the Commonwealth of Australia, holding office on commission from the Governor-General of Australia. They are the highest-paid Member of Parliament.
There is no fixed role that each person occupying the office must perform. Instead there is a range of potential capacities, and within limitations they have an opportunity to enhance the position depending on their vision and other qualities.
Julia Gillard was the first female Prime Minister of Australia; being at that time the leader of the Australian Labor Party. Former Prime Minister Kevin Rudd was sworn in (again) as Prime Minister on the 27th of June 2013 after a leadership victory over Julia Gillard three years and three days after being ousted by Julia Gillard.
