The club originally competed in the Northern Suburbs Soccer Association (NSSA). The original playing strip was a red and white shirt, white shorts and red and white hooped socks. In 1973, Northbridge joined the Ku-Ring-Gai and District Soccer Association (now the Northern Suburbs Football Association).
