Jabarkan Support dari Derbi Sydney

Both Wanderers' and Sydney's fan bases are multi-ethnic, due to the racial diversity in Sydney. The western Sydney region especially is the most multicultural and culturally diverse region in Australia. Sydney fans call themselves "The Cove" – a reference to original name given to the colonial settlement of Sydney – Sydney Cove. Wanderers fans call themselves the "Red and Black Bloc" (RBB) – a reference to the club colours (red and black). Wanderers have also become a source of pride in an area whose residents are often disparaged as "Westie". This is exemplified in one of the RBB's chants, "These Colours Unite Us All", which celebrates the diversity of the club, its location and its fans. The chant continues, "All the places we're from, in this city we own, we call West Sydney home". Both fan groups actively despise each other, which is why the derby is considered so important.

Sydney FC fans sprawl from across the Sydney CBD, from Hawkesbury to the Shire, and the Inner West. The fans and club have a strong relationship, strengthened by good relations with SCG Trust – the owners of Sydney Football Stadium. The club has played games across Sydney throughout several competitions, including Leichhardt Oval in the Inner West, Cromer Park in North Sydney, and several W-League games in Sutherland Shire.
