Parramatta Junior Rugby League formed in 1946, when, as a result of expanding urban sprawl an influx of residents flocked to the immediate Parramatta area in Sydney, this caused a compacted competition to be formed and the Western Districts and Southern Districts competitions were revamped. In its fledgling years the competitions took in teams from far adrift as Liverpool and St Marys and just about every town on the Cumberland plateau.
