The President is elected by the Senate in a secret ballot. The Clerk conducts the election. The Presidency has always been a partisan office and the nominee of the government party has nearly always been elected—although this cannot be guaranteed since the government of the day does not necessarily have a majority in the Senate. The President is assisted by an elected Deputy President. The traditional practice has been that the government nominates a Senator to be elected as President, and the Opposition nominates a Senator to be Deputy President. If there are no other nominations, no election is required, however the Australian Greens in 2005 and again in 2007 put forward Senator Kerry Nettle as a rival candidate when the position of President was vacant. Neither Government nor Opposition Senators supported that candidacy.
Role
Parliamentary duties
The President's principal duty is to preside over the Senate, to maintain order in the Senate, uphold the Standing Orders and protect the rights of backbench Senators. He or she is assisted by the Deputy President and a panel of Acting Deputy presidents, who usually preside during routine debates. Although the President does not have the same degree of disciplinary power as the Speaker does, the Senate is not as rowdy as most Australian legislative chambers, and thus his or her disciplinary powers are seldom exercised. Unlike the Speaker the President has a deliberative, but not a casting vote. This is because the Senate is in theory a states' house, and depriving the President of a deliberative vote would have robbed one of the states or territories one of its Senators' votes.
Administrative duties
The senate president is the chief executive of the Department of the Senate, which is one of the four parliamentary departments. He or she chairs the department's budget committee and oversees its organisational structure. The president also co-administers the Department of Parliament Services with the Speaker of the House of Representatives.
Ceremonial duties
The President of the Senate is ranked highly in the Commonwealth Table of Precedence, either before or after the Speaker of the House of Representatives depending on seniority. He or she participates in the state opening of parliament, represents the parliament on overseas visits, and receives visiting delegations from other countries.
Salary
As with all other parliamentarians, the President of the Senate's salary is determined by the Remuneration Tribunal, an independent statutory body. As of 1 July 2019, the base salary for senators is A$211,242. The President is entitled to an additional "salary of office" comprising 75% of the base salary, making for a total salary of $369,674 per annum. He or she also receives the various other entitlements and allowances available to senators.
The position of President of the Senate has been disproportionately held by Senators representing the least populous states and territories. There have been 25 presidents of the Senate since 1901. Of these 15 have come from the least populous states or the Australian Capital Territory, and 10 have come from the three most populous states. All senate presidents have been members of major parties, though not necessarily the governing party.
Deputy President
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.
List
There have been 36 Deputy Presidents of the Senate, two of whom served multiple non-consecutive terms.
