Finally got some info about RMC and Shield. There'll be a small 3-round pre-season comp for RMC which will be used to establish a top four who'll progress to the NSWRL/CRL challenge cup later in the year.
Shield will have 3 weeks of trials alongside that.
Those 3 weeks for both grades coincide with R1-3 of the ISP/Flegg comps.
The season proper kicks off the weekend after Easter (April 7 and 8) and runs for 20 rounds. There's a weekend break at the start of June but they keep playing the weekend of the Origin II game which most other comps take off.
