Originally set for March 2010, the revised deadline of June 30 has been granted by the region's governing body.

AFC say it provides FFA further opportunity to continue discussions with relevant parties in Australia such as government and other stakeholders.

"[In order] to formalise the relevant guarantees and facility agreements, which are part of the bid submission," reported AFC today.

This will be followed by FFA's final presentation of their bid to the AFC Executive Committee on July 30, 2010.

AFC officials ran their eye over Australia's prospective stadiums and facilities last September - a trip that included taking in some live A-League games.

Australia were the only country to put in an intensive bid to host the 2015 edition of the continental showcase before AFC's deadline of March, 2008.

In other Asian Cup news, should Australia qualify for the 2011 edition in Qatar, the FFA sre still deciding on whether to continue to run regular A-League fixture scheduling through January.

A-League-based players may be required for the Socceroos in the tournament that runs from January 7 to 29.

A-League supremo Archie Fraser told au.fourfourtwo.com: "We are working through this and a number of other factors on the draw for season six."
