The derby was contested for the first time in the 2012–13 season with the introduction of the second Sydney-based club, Western Sydney Wanderers, into the league. Sydney FC grabbed bragging rights by winning the first derby 1–0 at Parramatta Stadium, however Western Sydney Wanderers won the return match at Allianz Stadium 2–0. A Sydney Derby held early in the 2015 season broke the Allianz Stadium record for attendance during a regular season in any football code, dating back to the stadium's opening in 1988. A match in 2016 between the two teams broke the record A-League crowd with 61,880 fans attending the match at ANZ Stadium. Sydney Derby is intensified by the geographic distinction between the two clubs within Sydney, as well as historical grievances related to the foundation of Sydney FC.
