The new Perth Arena's spectacular retractable roof was revealed for the first time this morning.
Premier Colin Barnett said a gala arena opening would be held for Perth residents on November 10.
The long-awaited sport and entertainment venue features a retractable roof which closes in seven minutes.
"Practical completion will occur in August as previously announced with a three-month commissioning period including all system testing, furnishing, training and a series of test events to follow," Mr Barnett said. "The people of Western Australia can expect a very exciting opening program that will allow the community access to fully experience the venue.
"While it cost more than it should have, I'm confident the arena will prove to be a wonderful venue for all West Australians to enjoy."
Sport and Recreation Minister Terry Waldron said the venue, which was built with more than 6250 tonnes of Australian steel, would be a multipurpose facility equipped for everything from concerts for 15,500 fans, to Hopman Cup tennis and dozens of other uses.
"Having this facility means we will see many more touring acts than ever before choose Perth for shows and events," Mr Waldron said.
The Premier and Minister today also revealed the opening roof with the first public showing of this unique feature.
