The Socceroos will face the Lebanese on 6 September to fine-tune their squad ahead of a 2014 FIFA World Cup Brazil™ qualifier against Jordan in Amman five days later. Lebanon, meanwhile, play a home Brazil 2014 qualifier against Iran on the same date.
"This match against Lebanon will be an ideal opportunity for us to face quality opposition who play a similar style of football to our next opponents in the World Cup Asian qualifiers," said Australia coach Holger Osieck.
Australia are currently third in Group B in final Asian FIFA World Cup qualifying with two points from two games, the same as Iraq. Japan are top on seven points from three matches.
Lebanon have just one point from their three Group A matches to date.
