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 Australia's permanent Parliament House was delayed while its location was debated. Construction of the new building began in 1981.
The principal 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.
