context_page_description: The President of the Senate is the presiding officer of the Australian Senate, the upper house of the Parliament of 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.
  The President of the Senate's primary task is to maintain parliamentary procedure in the chamber during legislative sessions. Unlike the Speaker of the House, he or she votes as an ordinary member during general debate, and has no casting vote in the case of a tie. The President of Senate has also various administrative and ceremonial duties, sharing responsibility for the management of Parliament House and other parliamentary facilities and services with the Speaker of the House.
context_section_description: As well as a president, the Senate also elects a Deputy President, whose formal title is Deputy President and Chairman of Committees. Until 1981, the title was just Chairman of Committees; it was changed "to reflect more accurately the nature of the office in practice". The position is not provided for by the constitution, but instead by the Senate's standing orders – it was borrowed more or less directly from the colonial legislative councils. The deputy president's main tasks are to preside over committees of the whole and to serve as presiding officer when the President of the Senate is absent.
