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
The Australian Greens appointed their first whip in the Senate when the party increased from two to four members in 2005. She became entitled to a salary when the party increased to five members in 2008.
One Nation first entered the Senate in 1999, but had only one seat and consequently did not elect a whip. The party's senator was defeated in 2004 and left the Senate in 2005. In 2016, four One Nation senators were elected, and the party elected a whip for the first time.
