Australia was willing and able to step in to host the 2022 World Cup if Qatar was sensationally stripped of the event, the chief Asian Cup organiser said at the G20 in Brisbane on Wednesday.

German magazine Der Spiegel has reported FIFA president Sepp Blatter told guests at an October 13 dinner in Oslo, Norway: "The World Cup will not take place in Qatar."

FIFA has issued denials over Mr Blatter's alleged comments.

Australia will host the 2015 AFC Asian Cup in January next year in Sydney, Melbourne, Brisbane, Newcastle and Canberra.
