The state government’s planned $810 million refurbishment of ANZ Stadium at Olympic Park would deliver fewer “blockbuster” events than a completely new stadium and would not result in the same increase in fan attendance, the government’s business case for the project says.

And the business case for a new stadium at Moore Park assumes that it draws more NRL fixtures from suburban grounds in Sydney.

The Berejiklian government was last week forced to release the full business cases for its controversial scheme of building a new 40-45,000 seat stadium at Moore Park for $730 million and refurbishing ANZ Stadium at Olympic Park into a permanently rectangular 70,000 seat stadium for $810 million.

That policy, however, represented a back-down on Premier Gladys Berejiklian’s prior position of wanting to build a completely new stadium to replace ANZ at Olympic Park, at a cost of $1.3 billion.
