The local derbies against St George in the Matthews Cup and SG Ball, as well as the Tarsha Gale Cup clash between the Sharks and Panthers, have been abandoned due to ground conditions, the weather and the prediction of further heavy rain to come.
The NSWRL decision includes all round five fixtures, with the competitions to continue as per normal on the weekend of March 12-13, where wet weather make-up games from round 4 will be played.
Round 6 will commence on March 19, with no changes to the remaining rounds and final series.
There will be no competition points allocated for round five.
The Sharks Matthews Cup team has a round 4 game against the Central Coast Roosters to make up, with the SG Ball Sharks to be back in action in round six after beating the Victorian Thunderbirds in their round four match last weekend.
Details of next week's Matthews Cup fixture will be communicated once confirmed.
