Senate (Australia)

Senate (Australia)

The Senate is the upper house of the bicameral Parliament of Australia, the lower house being the House of Representatives. The composition and powers of the Senate are established in Chapter I, Part II of the Australian Constitution. Each Australian state is represented by twelve senators, regardless of population. Senators are popularly elected under a system of proportional representation. Senators serve staggered six-year terms; however after a double dissolution some senators only serve three year terms. Significant power is conferred upon the Senate by the Constitution, including the capacity to block legislation initiated by the government in the House of Representatives, making it a distinctive hybrid of British Westminster bicameralism and US-style bicameralism.

The present Parliament, as elected at the 2010 election, is the 43rd Federal Parliament since Federation. In the 76-seat Senate, where no party tends to have a majority of seats, the Greens gained the sole balance of power with a total of nine seats, previously holding a shared balance of power with the Family First Party and independent Nick Xenophon. Labor holding 31 seats, they require an additional eight non-Labor votes to pass legislation. The Coalition holds 34 seats, while the two remaining seats are occupied by Xenophon and Democratic Labor Party Senator John Madigan.
