Final agreements between FFA and rival sporting codes were signed over the weekend, completing the requirements from FIFA to have the support of the other major sporting codes.

"We have the unified support of the nation behind our Bid and we are ready to host the biggest sporting event in the world," FFA Chairman Frank Lowy said.

"This is great news for football and great news for the whole country as everyone will benefit if we win the right to host a FIFA World Cup.

"I would especially like to thank the Government Taskforce, Federal Sports Minister Kate Ellis and the State and Territory Governments for their tireless work in bringing everyone together."

FFA CEO Ben Buckley is confident Australia has a compelling case for consideration of either the 2018 or 2022 event.

"We are a safe pair of hands and have the experience, stability and certainty to hold such a major event," Buckley said.

"The host cities and stadia we are using in our Bid will showcase Australia to the rest of the world and combined with our sports loving culture and the friendliest volunteers in the world it will be a fantastic FIFA World Cup.

"I would like to thank all of the parties involved to this point for approaching negotiations in good faith and for the constructive manner in which they worked through the issues."

AFL boss Andrew Demetriou also threw his support behind the bid after receiving confirmation on Sunday that the season would not be interrupted by the World Cup.

"We have consistently supported Australia's bid for the World Cup as we have with other major sporting events," he said.

"We know it will cause serious dislocation of our AFL season, including up to 90 games that will need to be relocated and/or rescheduled, but we also accept that all codes need to make accommodations to ensure major events come to Australia."

Under a Memorandum Of Understanding signed on Sunday, the AFL agreed to give up the use of the MCG, Perth's Subiaco Oval, Geelong's Skilled Stadium, Gold Coast Stadium and the Adelaide Oval for 10 weeks if Australia's bid was successful.

Demetriou said the use of Etihad Stadium was pivotal in the agreement.

"That's was exactly why it so important we retained Etihad Stadium," he said on Monday.

"We were very clear that if Etihad Stadium was part of the World Cup bid, we certainly couldn't have played our season."

Demetriou said matches would be played around the country, including in Tasmania, Darwin and 'other states where we normally wouldn't play home games'.
