We'll find out just how popular the Big Bash is next year. There's an article in the Sunday Times saying how because of the temporary stands set up for the Ashes, they'll be leaving it up for the Big Bash. That means capacity will be lifted to 24,000, an extra 6000 seats. If crowds increase notably as well (they'll need to sell a little more than half of the temporary seats to break even in the costs to set it up) then the WACA will look at setting them up every year for the Big Bash.
