WA Premier Colin Barnett has announced that the long-awaited gala opening of the Perth Arena will take place on November 10.

The Premier Colin Barnett says he is confident the Perth Arena will be opened in November without any further cost blowouts.

The arena has been plagued by delays and the costs have blown out to more than three times its original estimate.

The half a billion dollar venue is expected to be completed in August and then opened to the public following a three month commissioning phase.

‘While this project has had some controversy, particularly over the cost of it, it’s time now to move on,’ he told reporters.

‘There’s no doubt this is going to be a magnificent facility,’ he said.

“Around $550 million is the final cost,  it was supposed to be 160, but as I said, that’s now history, we move on, and this is going to be a stunning venue for Perth,” he said.

It will seat around 15,000 people and features a retractable roof and state-of-the-art entertainment technology.

The multipurpose venue will host Hopman Cup tennis and other sporting events, including becoming the new home of the NBL Perth Wildcats.

The Perth Wildcats say the opening date will force them to move some of their home games.

Wildcats CEO Nick Marvin says the team will be under pressure as a result.

“We always knew we were gonna miss a week or two but to miss seven effectively seven weeks at the start of our season and perhaps four or five over Christmas it will put pressure, if we can fit it in, it will put pressure on the team to perform because we will be seven weeks on the road,” he said.
