Part of the Burswood Entertainment complex, the Burswood Dome is one of the largest enclosed entertainment, sports and special events venue in Australia. With an arena equivalent in size to an international soccer pitch, the Dome is designed to stage the largest of events with total seating capacity for up to 20,000 people with the use of temporary seating. Its vast arena covers 8,800 square metres (118 x 74.5 metres) and is surrounded by permanent tiered seating for 13,600 people. A feature of the Dome's design is the enormous inflated teflon coated fibreglass roof which soars to a height of 35 metres. A ground support system is available to hang large concert production rigs. The domed roof enables natural light to filter into the complex and is held in position by a series of cables arranged in a special grid pattern. Eight huge fans maintain constant air pressure to ensure the roof is fully inflated at all times.
