Sydney Olympic Park. $150m makeover possible

The ANZ Stadium, at Sydney Olympic Park could be transformed into a rectangular venue to host a World Cup final, with a roof over the stadium and an extra 7000 seats, increasing the ground's capacity to 90,000 in a $150 million makeover that could knock out Melbourne and ensure Sydney wins the fight to be Australia's nominated host for the final. A high-tech, retractable and transparent roof, the first of its kind in the southern hemisphere, would protect fans from the elements and let natural light filter through.
