About the Senate
The Senate is one of the two houses of the Australian Federal Parliament. It consists of 76 senators, twelve from each of the six states and two from each of the mainland territories. It shares the power to make laws with the other House of Parliament, the House of Representatives. The Senate is elected by proportional representation, so that its composition closely reflects the voting pattern of the electors.
Powers
The powers of the two houses of the Commonwealth Parliament, the Senate and the House of Representatives, are defined by the Australian Constitution. All proposed laws (bills) must be passed by both houses. The Senate's law-making powers are equal to those of the House of Representatives except that it cannot introduce or amend proposed laws that authorise expenditure for the ordinary annual services of the government or that impose taxation. The Senate can, however, request that the House of Representatives make amendments to financial legislation and it can refuse to pass any bill.
Composition
Under the Constitution, each state of the Australian federation, regardless of its population, has an equal number of senators. The Senate currently consists of 76 senators. Twelve senators represent each of the six states, elected for a period of six years. A system of rotation, however, ensures that half the Senate retires every three years. The four senators who represent the Australian Capital Territory and the Northern Territory are elected concurrently with members of the House of Representatives and the duration of their terms of office coincide with those for that House (a maximum of three years).
The Senate is elected by a system of proportional representation which ensures that the composition of the Senate more accurately reflects the votes of the electors than the method used to elect members of the House of Representatives.
Role
The Senate is a house of review and a powerful check on the government of the day. The proportional representation system of voting used to elect senators makes it easier for independents and the candidates of the smaller parties to be elected. In recent decades this has meant that the government party usually does not have a majority of votes in the Senate and the non–government senators are able to use their combined voting power to reject or amend government legislation. The Senate's large and active committee system also enables senators to inquire into policy issues in depth and to scrutinise the way laws and policies are administered by ministers and public servants.
Senate committees
The Senate’s role as a house of review and as a watchdog of the executive branch of government has led to the development of a comprehensive range of committees which may investigate matters of public policy and scrutinise proposed legislation and the details of government expenditure and administration. Most senators are actively involved in the work of three or four of these committees.
Senate committees fall into two categories—Select and Standing.
A select committee is one appointed by the Senate to inquire into some specific matter and to report back to the Senate within a set time. Once a select committee has submitted its final report to the Senate its work is done and it ceases to exist.
A standing committee is a permanent committee of the Senate. It stands—or remains—for the life of the whole of any one Parliament, its members being appointed at the commencement of each Parliament. There are three groups of standing committees:
Domestic committees
These committees deal with matters relating to the internal operations of the Senate, including publications, appropriations and staffing, procedure, privileges, library services, the provision of facilities in Parliament House and senators’ pecuniary and other interests.
Legislative scrutiny committees
All bills and subordinate legislative instruments that come before Parliament are scrutinised by either the Scrutiny of Bills Committee or the Regulations and Ordinances Committee to ensure that they conform to certain principles mainly concerned with personal rights and civil liberties.
Legislative and general purpose standing committees
These committees examine legislation, government administration and public policy. The committees are divided along subject lines and cover between them all areas of government responsibility.
In the Australian system of government, ministers and public servants are accountable to the Parliament for the use of the public resources with which they have been entrusted. Legislative and general purpose standing committees carry out the work of inquiring into and reporting on the twice-yearly estimates of proposed government expenditure. In addition, they have a specific mandate to monitor the performance of departments and agencies. At the estimates hearings senators may directly question ministers and public officials not only about the details of proposed expenditure but also about the objectives, operations and efficiency of the programs for which they are responsible.
