The bitter political war embroiling Australian football's governing body is set to rumble on, with FIFA's looming intervention unlikely to arrive at a solution to Football Federation Australia's congress crisis. 

A joint mission between the governing body of world football and the Asian Football Confederation will arrive in Sydney on November 20 for three days of talks to establish a Congress Working Group to help the FFA expand its membership tier. 

However, it's unlikely to provide an immediate resolution to the crisis that's put the FFA at war with the clubs, players and the two biggest state member federations. Embattled FFA chairman Steven Lowy says it could take several months longer before there is any clarity over the expansion of the organisation's congress and the joint FIFA/AFC mission will only establish the framework for the next stage of the process. 

Already, the issue over the expansion of the FFA congress has been simmering for nearly 18 months and is holding back the establishment of a new A-League Operating Model that is required before expansion of the competition can take place.

"It may take a lot of time but the path and the objectives will be set when they visit here in a few weeks and we look forward to that," Lowy said.

"It's worthy of debate – serious issue, changing the congress. It's clearly had a lot of debate in the last 18 months or so and it needs to be done properly. The board of the FFA is very conscious that it's very important to expand the congress of FFA but it's equally important to do it properly.

"We don't expect an end result. Clearly the process we've been through there are many differences that are well known to everybody and we really need to regroup."

FFA has been ordered by FIFA to expand its congress to become more inclusive and representative of its stakeholders.
