Hunter was formed in mid 1995 and was later disbanded at the end of 1997. The club was formed because of the Super League war, which was the rivalry between the traditional Australian Rugby League competition and the new media driven Super League competition. The team competed in the inaugural and only Super League season in 1997, as well as that year`s World Club Challenge.
