The veteran Australian goalkeeper is out of contract at Craven Cottage next month and is likely to move on after the Southwest London club signed Dutch gloveman Maarten Stekelenburg from AS Roma.
"That's what I've heard (that Stekelenburg has signed) and I've been hearing that for a while so it's no great surprise and I'll be looking for another club," he told the Daily Telegraph.
"Nothing has been sorted at the moment, the Japan game was the most important thing on the agenda so I'm worried about the Australia World Cup qualification) games now (against Jordan and Iraq).”
"Not at this stage, no. My family's settled and the kids are in school and I wouldn't (move) my family anyway,” he added.
"And when you talk about the length of season it's never ideal when it finishes in April, so as far as I'm concerned I'll try and stay in Europe for as long as possible and England would be ideal."
