Both the AFL and the NRL have voiced loud concerns this week over the potential impact a World Cup would have on their respective codes.

This has led to fears that such squabbling could seriously damage Australia's chances of earning either the 2018 or 2022 tournaments.

However PFA CEO Brendan Schwab is confident that FIFA will see Australia as too big an opportunity to ignore and that powerful 'positives' will holder greater sway than rival codes' concerns.

"Australia is part of Asia and this country hosting the World Cup would allow FIFA and the game to make a massive footprint in this part of the world," Schwab told au.fourfourtwo.com today.

"I think FIFA understand how important it is to have the World Cup in Asia and how big the potential market is.

"Football has the ability to bring people together like no other sport can. I think a World Cup for Australia would provide a wonderful sporting legacy.

"I think they are wrong to think that FIFA would be pushed away by the challenge, I think they would be emboldened by it. I don't think it will drive a wedge.

"What they will look at is a Prime Minister backing this bid, letters of support from levels of government, football fans and of course proof of the financial commitment that backs up that support.

"FIFA's  executive committee understands just how competitive a sporting market this is and a World Cup would be a tremendous opportunity to further drive football forward.

"I travel around the world and people are well aware of the sporting set up here. They liken it to the United States of America."

Schwab said a World Cup on these shores would be important in the near future and for Australians in the decades that would follow.

"We have a chance to host an event that would leave all the foreign visitors to enjoy the tournament and then head home saying to themselves that Australia is a football nation," he said.

"We are also left with the infrastructure from the event which Australians will benefit from."

The PFA boss reiterated that FIFA's drive to spread the world game far and wide was a powerful factor in making a final decision on hosting rights

Schwab added: "FIFA is driven by its desire for the development of the game. These people are football missionaries. 

"Asia is a market that has huge potential and Australia is a big part of that market. I firmly believe Australia will be a greater nation for hosting the World Cup."
