The Big Brother House is a purpose-built house/studio for filming of Australia's "Big Brother" reality TV series. When not in use for filming, Dreamworld visitors can take self-guided tours through the House and the camera runs, and have a photo taken in the famous Diary Room chair. While the exterior of the House is nothing more than a white tin shed, the interior is a fully functional house that is home to over 20 contentsants on the show for 14 weeks each year. The interior walls are lined with two-way mirrors allowing dozens of cameras to capture every angle of the house.
Big Brother Studios is both an open-air auditorium used for live Big Brother shows such as Evictions, Nominations, and Friday Night Live, and a TV production studio and offices. Footage from the House is monitored and edited in this facility 24 hours a day. During the series, Dreamworld visitors can tour the stage and watch the production team at work, as well as see live footage from the House.
The interior of the house is rebuilt between TV seasons (Jan-Apr). Filming runs from Apr-Aug. The House is open for inspection Aug-Dec each year.
The amphitheatre that is now part of Big Brother Studios was an existing facility at Dreamworld long before Big Brother began, and was used for live stage shows. It is now leased to Endemol/Southern Star for the duration of the series each year. The current contract gives ESS use of the Studios and Big Brother House until 2009.
