He finally decided to return home to Australia after spending 10 years abroad, joining new A-League club Sydney FC. It was a shaky start to the new competition for Corica, sent off in Sydney's third A-League match against Newcastle for a dangerous foul. After serving a one match suspension, he repaid the club scoring just five minutes in against Queensland Roar, and following up with a second goal later in the match. Corica retained a place in the side for much of the year as Sydney progressed to the Grand Final. A set-up from Dwight Yorke in the second half, gave Corica the only goal in Sydney FC's 1–0 victory over the Central Coast Mariners to help the team win the inaugural A-League Championship.
