The schoolboys rugby league competition was set to start at 4.30pm before being called off on Monday morning.

On Sunday the NSW Department of Education introduced proactive measures to limit the impact.

It included temporarily stopping whole-school sporting events and inter-school events involving three or more schools.

Convenor Ryan Price said the safety of players, staff and the wider community are paramount.

There is also uncertainty if the competition can be rescheduled.

"We may look to rescheduled but at the moment we won't be going ahead as it currently stands," Price said.

"We don't how long bans will last for but at this stage it will be cancelled with no new date set.

"We will cross that bridge if we can find a time but the sports calendar is pretty heavy with times as there is AFL, soccer and everything else to fit in as well.

"We might not fit it in."
