This means Group 10; the Wallerawang Landscaping Cup (formerly known as New Era Cup) where the Oberon Tigers will be playing; Woodbridge Cup; Group 11; and the Castlereagh Cup are all pushed back by six weeks.

The decision was announced by NSW Rugby League in partnership with the NRL and all affiliated states following advice from the NRL chief medical officer Paul Bloomfield and government agencies.

NSWRL chief executive David Trodden said the recommendation covers all rugby league matches, trials, training, courses and other club activities in NSW and is made with the health and wellbeing of players, coaches, staff, officials and volunteers and the broader community as a paramount consideration to assist in slowing the spread of the COVID-19 virus.

It's the last major sporting code to be postponed, with nearly every other code shut down until May.

The Group 10 competition was due to kick off on Easter Friday but will now be pushed back.

The league is yet to determine what it means for fixtures and dates.

GROUP 10 president Linore Zamparini says the competition could deal with a May 1 start date, but it would face real struggles if it stretched past that point.

"If it's May 1 we'll survive, but if it's longer than that, we'll certainly be in a bit of trouble, he said.

"We can only follow the advice that's given from the health department and the government.

"They've obviously come up with a scenario that it's the safest thing to do under the circumstances."

Many Group 10 clubs start their pre-seasons as early as December-January and the president's got the utmost sympathy for teams that have been putting in the hard yards for months.

"A lot of these guys are nearly at peak fitness and now they've got to sit around for a month," Zamparini said.

"They [NSW Rugby League] is recommending they don't train in groups, so that makes it hard.

"At the end of the day, the safety of everyone is paramount and if we can't train and play then that's the way it's got to be."
