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.
Parliament of Australia
The upper house of the Australian Parliament is the Senate, which consists of 76 members. Like the United States Senate, on which it was partly modelled, the Australian Senate includes an equal number of Senators from each state, regardless of population. Unlike it, however, the Australian Senate has always been directly elected. (The US Senate has been directly elected only from 1913.)
