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.
List of whips in the Australian Senate
Whips have managed business and maintained party discipline for Australia's federal political parties in the Senate since Federation. Though the Remuneration Tribunal and parliamentary website refer to the senior Labor and Liberal whips as "chief" whips and their junior whips as "deputy whips", the parties tend to refer to the senior whips as "whips" when announcing their officeholders to the Senate. A number of Senate whips have gone on to serve as ministers, and several as Leader of the Government or Leader of the Opposition in the Senate.
