President of the Senate (Australia)
The position is provided for by Section 17 of the Constitution of Australia. The Senate elects one of its members as president at the start of each new term, or whenever the position is vacant. This is usually—though not necessarily—a member of the party or coalition that holds the most seats in the Senate. The largest party in the Senate is not always the governing party, as government is determined by the House of Representatives. The President of the Senate and the Speaker of the House of Representatives may consequently be from different parties.
Politics of Australia
The role of head of state in Australia is divided between two people: the Monarch of Australia and the Governor-General of Australia. The functions and roles of the Governor-General include appointing ambassadors, ministers, and judges, giving Royal Assent to legislation (also a role of the monarch), issuing writs for elections and bestowing honours. The Governor-General is the President of the Federal Executive Council and Commander-in-Chief of the Australian Defence Force. These posts are held under the authority of the Australian Constitution. In practice, barring exceptional circumstances, the Governor-General exercises these powers only on the advice of the Prime Minister. As such, the role of Governor-General is often described as a largely ceremonial position.
