The Chanel College Education Funds, the Chanel College Parents, Teachers and Friends Association, and the Gymnasium Building Committee also had helped raise funds, he said.
"We really appreciate the support of the community for the fundraising and as soon as the consent process is through, then we'll be finally under way."
Mr Miles said about $30,000 was still needed to support the project but enough funds were now in hand to begin construction.
"We're basically there and the gymnasium will be great for the school, great for the students and for the community, who will also benefit from it. "
The multi-purpose gymnasium will border the school hall and the No1 soccer ground, and will house a basketball court, a tennis court, four volleyball courts, a netball court, five badminton courts, an indoor hockey court, and static weights and fitness training areas.
There also will be a mezzanine floor that incorporates a classroom, kitchen and a viewing gallery, and the gym will be available for community use.
