Buckley met with South Australian sports minister Michael Wright this week to discuss the possibility of Adelaide hosting matches at either the 2018 or 2022 World Cup should Australia win the hosting rights to either tournament.

There is an existing plan to extend Adelaide Oval to 36,000 capacity, but Buckley has told Wright that would not be big enough to be part of any bid. The SA government has ruled out any chance of building a new stadium for the event.

But Buckley denies the discussions involved an ultimatum to the SA government to either build a suitable stadium or miss out.

"At no stage did we issue an ultimatum," Buckley said. "It has always been our view that the bid for the 2018/2022 FIFA World Cup is a national one and we want to ensure Adelaide is part of it."

Buckley said the purpose of the meeting was to inform the Government of some key timelines related to the bid and to brief them on FIFA's technical requirements.

"I also advised that FIFA's technical requirements include a minimum capacity of in excess of 40,000 spectators," he said.

FFA has to decide on the cities and stadiums which will be included in their bid by the end of this year.

"This does not mean the stadium has to be built or even has to be commenced in that timeframe," he said. "It simply means that there needs to be a commitment to a FIFA compliant option on the basis that the bid is successful.

"We've always been committed to a solution in Adelaide to ensure it is part of a successful bid, and we look forward to continuing to work constructively with the South Australian government to make that happen."
