The 33-year-old who underlined his importance to the national team with a goal in last month’s 4-2 victory over Saudi Arabia in Melbourne is considering the possibilities, which include a possible stint in the MLS or Asia.
However, with the transfer window in China closed and Japanese clubs not keen on what they perceive as gimmicks, that only leaves South Korea or the United States as a viable option.
Nine weeks stand between Melbourne Victory’s final A-League game on Saturday at Perth Glory and Australia's friendly against Denmark in Copenhagen in early 2 June – which leads into the World Cup qualifier in Oman.
'Harry is determined to play for the Socceroos as long as he can and with that in mind he is looking at all his options and possibilities," Kewell’s agent James Erskine said.
'We are obviously not going to announce anything until it is locked in. His main is goal is to play at the next World Cup and to do that he knows he has to be at the top of his game.
'I am sure if Harry is playing well he will be selected."
Kewell, wife Sheree and their four children return to England next week for a break at the conclusion of his first A-League campaign.
'It’s really just a holiday for Harry and his family," Erskine said.
With eight goals in 24 starts for Victory this season, the 56-times-capped Kewell produced his best A-League form as his fitness levels improved and knows that his chances of featuring for the Socceroos in June – which also includes a home qualifier against Japan in Brisbane on 12 June – hinge on finding club football elsewhere.
Kewell’s conundrum is shared by several other A-League Socceroos including team-mate Archie Thompson, Sydney FC’s Brett Emerton and Nicky Carle, Adelaide United’s Dario Vidosic, Brisbane Roar’s Mitch Nichols and Erik Paartalu and Gold Coast United's Perth Glory-bound Michael Thwaite.
One scenario could be a team composed of Socceroos possibles under the auspices of FFA playing games against the three Australian teams competing in the AFC Champions league –Adelaide United, Brisbane Roar and Central Coast Mariners.
Beyond June, there are whispers that while Kewell has two years left on his Victory contract, should FFA install a new team in western Sydney next season he could be recruited as the face of the franchise in his home city.
Meanwhile, the revamp of Victory's squad for next season will include exit of Jean Carlos Solorzano.
The Costa Rican striker was linked with a possible move to Melbourne Heart but now appears destined to return to LD Alajuelense, from which he is on loan.
