Sydney FC is one of the best-supported soccer clubs across the nation, particularly in the city’s more popular town, Sydney. Sydney FC is the most successful club in Australian football history, having won 25 trophies across all domestic and international competitions. Sydney FC is the most successful association football club in Australian history, having won five league titles and four premierships in the nation’s top-level men’s competition, in addition to an FFA Cup title and the Oceania Champion League title in 2005, before the government joined the Asian Football Confederation. As the only Sydney-based club to compete in the nation’s top men’s competition before 2012, Sydney FC previously attracted the support of much of Sydney (much of which has been taken back by Western Sydney Wanderers FC as of the clubs founding in 2004), and is, therefore, one of the strongest supported clubs in Eastern Sydney.

Sky blue, the official colour of New South Wales, serves as Sydney FC’s official club colour. The club’s secondary colour is navy blue, with the bright colours orange and white also present. However, orange is not included in the club’s 2017 crest makeover. The Cove, Sydney FC‘s fan organisation, presented a design that has been modified into the club’s current emblem, which was unveiled on May 17, 2017. The Sydney Opera House in white is shown on the crest against a sky-blue background, sitting on a navy base with the Commonwealth Star. The number five is engraved inside a silver star on the emblem, which stands for the number of championships the team has won.

According to Roy Morgan’s latest research, over 3.6 million Australians now support an A-League club, an annual growth of more than one million new fans. Recent findings from Roy Morgan have found that Sydney FC is the most supported club in the A-League, with 640,000 Australians aged 14 and older supporting the Sky Blues. The club’s first experience of success came before the establishment of the A-League when it won the Australian Championship in 2005 and went on to be named Oceania’s Champions, earning a spot in the 2005 Club World Championships in Japan, where it placed fifth.

After Graham Arnold was appointed head coach, the team acquired Austrian captain Marc Janko from Trabzonspor of Turkey. In the A-League 2014–15 season, Janko established a new record for the most goals scored by a Sky Blue player in a season (16), surpassing Del Piero’s previous mark of 14. On March 14, 2015, he scored against Brisbane Roar for the seventh game in a row, setting a new league record for most goals scored in consecutive games.
