Parliament House is the meeting facility of the Parliament of Australia located in Canberra, the capital of Australia. The building was designed by Mitchell/Giurgola Architects and opened on 9 May 1988 by Elizabeth II, Queen of Australia. At the time of the construction, it was the most expensive building in the Southern Hemisphere at more than A$1.1 billion.
Federal Parliament meetings were first held in Melbourne until 1927. Prior to 1988, the Parliament of Australia met in the Provisional Parliament House, which is now known as "Old Parliament House". Construction of the Australia's permanent Parliament House was delayed while its location was debated. Construction of the new building began during 1981. The principle design of the structure is based on the shape of two boomerangs and is topped by an 81 metre flagpole.
It contains 4,700 rooms and many areas are open to the public. The main foyer contains a marble staircase and leads to the Great Hall which has a large tapestry on display. The House of Representatives chamber is decorated green while the Senate chamber has a red colour scheme. Between the two chambers is the Members' Hall which has a water feature and is not open to the public. The Ministerial Wing houses the office of the Prime Minister and other Ministers.
