A distinct rise in popularity in New South Wales and Victoria, among other states, was linked to the post-war immigration. Migrant players and supporters were prominent, providing the sport with a new but distinct profile. Soccer served as a cultural gateway for many emigrants, acting as a social lubricant. Soccer transcended cultural and language barriers in communities which bridged the gap between minority communities and other classes within the country, thus bringing about a unique unity. The most prominent soccer clubs in Australian cities during the 1950s and 1960s were based around migrant-ethnic groups, all of which expanded rapidly at that time: Croatian, Greek, Macedonian and Italian communities gave rise to most of the largest clubs, the most notable being South Melbourne (Greek-based), Sydney Olympic (Greek-based), Marconi Stallions (Italian-based), Adelaide City (Italian-based), Melbourne Knights (Croatian-based), Sydney United (Croatian-based) and Preston Lions (Macedonian-based).
