The 28-year old Socceroos midfielder received the proposal prior to the 2012/13 Championship campaign but knocked it back as he was determined to achieve success at Selhurst Park.
"There was an opportunity to go to Qatar but it was not the right time for me," he told SBS.
"I had only been at Palace for a season and I felt I had a lot more to give to the club.
"In the end it was a simple decision in terms of where I wanted to play my football.
"I'm glad I stuck with the club also because there is the chance of playing in the Premier League.
"I don't want to get ahead of myself but we are all hoping that we get there this season."
