Whips have managed business and maintained party discipline for Australia's federal political parties in the Senate since Federation. The term has origins in the British parliamentary system. 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.
