† Appearances (Goals).
He earned the ire of Newcastle United Jets fans in 2005, when he broke Andrew Durante's leg in a tackle during the Australian qualifiers for the Oceania Club Championship. He also scored a hat-trick in the same tournament, as Central Coast defeated Adelaide United 4–0. He later scored a hat-trick in the Mariners' 3–0 defeat of Queensland Roar in the Pre-Season Challenge Cup.
This was to remain the high-point of Mrdja's season as he was injured from the final of the Pre-Season Challenge Cup. Mrdja scored his first goal for the Mariners on 19 November 2006 against the New Zealand Knights, after almost two years on the sidelines. It was his first in Australia since scoring the winner in the 2004 NSL Grand Final.
