Kewell recalled for World Cup qualifier
Kewell missed Australia's last qualifier against Japan because of injury but has been included in a 22-man squad for the April 1 clash with Uzbekistan in Sydney.
Everton midfielder Tim Cahill was also named in the expanded squad despite being injured in his last match with English club Everton.
However, Australia will be without experienced defender Craig Moore and midfielder Vince Grella after they were ruled out with injuries.
"If you lose players like Craig Moore then you miss something but it is a chance for the other players to show what can do," Australia coach Pim Verbeek told reporters on Wednesday.
Australia currently lead their Asian qualifying group on 10 points, two ahead of Japan in second spot. Uzbekistan are last in the five-team group with one point.
