Australia have drawn a tough group in Brazil and will face World and European Champions Spain, Netherlands and Chile. They want to play a European team who have not qualified for the World Cup in their final preparation match before they head off to South America, on May 28 in Sydney's ANZ Stadium.
Reports in Australia suggested Scotland are their main target because there would be a full house of 80,000 fans due to the number of Scottish ex-pats in the country.
Gordon Strachan is keen to play some friendlies before qualification starts for Euro 2016 next season. But there would be no guarantee he would be able to call on his best squad for a far-flung tour at the end of the Scottish season.
