"It's the first time we've run this event. As a group of principals we get together twice a term and we were talking about the need to run an event for the junior children," she said.
"I've got some amazing feedback today from parents and teachers, so it's definitely going to be an annual event."
The event was originally going to be held in term one of 2018, but was postponed because of poor weather.
This time, the 334 children had prime conditions on a day that was also aimed at development for senior students.
"It's a leadership day for our senior students; they come along and they run the activities," Corcoran said.
"It's about building their leadership and giving them the opportunity to run these events without an adult."
Each school was tasked with running one activity for the students in Year 1, 2 and 3.
Corcoran said the activities would help to build their co-ordination, teach them about sportsmanship and develop their throwing skills.
"Cooks Gardens is the best place to do it. It's an awesome facility we've got here.
"There has been brilliant support, lots of parent help and heaps of happy kids who are enjoying themselves."
