In regards to the lack of NRC, obviously QLD and QRU do the challenger series which rewards the top Premier Grade players with a little series vs contracted Reds players.
I actually wrote to QRU last year while liking the whole series idea suggesting they could improve on it further with that lack of an NRC, by creating merit teams from all the different competitions around the state and having a mini states comp with maybe 2 teams from QPR, a team from Sunny Coast, Gold Coast, Northern Qld, Darling Downs which from that competition they select the challenger team for the Challenger series they do, only downside to it is cost but would help grow the game further state wide and reward players outside of the QPR catchment.
