The trophy was donated by QLD in 1984 and based on the results in the Australian Relay Championships, which at that time were for club-based teams. In 1997 the Relays changed to state-based teams. Before 1997 NSW was hamstrung by having smaller clubs than ACT and VIC, but since the switched to state-based teams NSW has dominated the competition.
