The club was formed in 1987 as a result of a merger of the senior teams of Perth Azzurri (formed 1948), East Fremantle Tricolore (formed 1953 - left merged club in 2004) and Balcatta Etna (formed 1977 - left merged club in 1991). The new club was known as Perth Italia. In the 1980s the club registered the name Perth United in anticipation of joining the National Soccer League.
Of the three clubs that merged in 1987, Azzurri was the most successful club having won 11 league titles. The club had its beginnings when a group of boys joined with the initial intention of starting an Australian rules football club. The club faced friction from the footballing establishment which disapproved of Azzurri's passionate style of play. Azzurri fully merged with Perth SC in 2002.
Between 1953 and 1987 Tricolore won six league titles including three straight wins between 1963 and 1965. Since leaving to play in their own right in 2004 they have played in the Football West Social League.
