Only 7000 general admission tickets are likely to be available for AFL games at the new Perth Stadium, and WA's premier has been quick to blame it on the previous government.

Former premier Colin Barnett promised last year there would be 10,000 general admission tickets at the stadium but it now appears likely to be 3000 fewer.

His successor, Mark McGowan, says when a contract is signed it's difficult to undo.

"We'll make it work as best we can with the arrangement that's been signed up," he told reporters on Monday.

"A contract's a contract. I don't want us to be sued."

But opposition leader and former treasurer Mike Nahan said to his knowledge nothing had been signed by the Barnett government for the 60,000-seat stadium.

"When we left government, negotiations were still live between AFL, Dockers, Eagles and the Football Commission," he told reporters.

Dr Nahan accused Mr McGowan of tyring to avoid the responsibility of leadership by always blaming the Barnett government.

Mr McGowan says the naming rights for the stadium remain on the agenda, with some interest already but he wants to keep "Perth" in the name.

The premier also described the delayed footbridge project, linking pedestrians to the stadium, as a "disaster" but could not confirm the Malaysian steel contract had been torn up in favour of a few local companies taking over.

Dr Nahan conceded the previous government had made an error by offshoring the contract.

"It should have been done here. It would have cost more to be done here ... we went for the lower cost option and that hasn't worked out adequately," he said.

Earlier this month, Mr McGowan controversially commented that he only wanted mid-strength beer served at the stadium, prompting the opposition to label his position as "stupid".
