Hegarty said that weathering the stormy weather would be a bonding experience for the group.
"They do a variety of activities around the camp related to the outdoor environment, trust activities, they get to know one another and their teachers in an outdoor setting."
Last night a group of boys had been allowed to camp away from the cabins but all the boys would spend tonight in a cabin.
Hegarty said a coordinator had been in touch with the group and described the mood as "buoyant".
"They are battened down to get through what's going to come today.
"They are like everybody: it's changed the nature of their day."
Based on the effects of the cyclone the school would decide tomorrow how the boys will come out. There would be a debate over whether they could walk or needed a water taxi, Hegarty said.
The next camp was due to go in tomorrow, and whether it would go ahead would also be decided after the cyclone.
