"Also, we've changed the day from Friday to Saturday to make it more of an extended Saturday afternoon family time," Fuller said.
"Hopefully we can put the event back on the map. We did have a bit of disappointment last year but that's been really contrasted by excitement now."
Fuller said despite focusing more on the community, the event was still the school's main fundraiser. This year, the school hopes to refit some of its playground equipment and returf its courts.
"Hopefully it will contribute to some of that."
Fuller said tickets were limited. The new health and safety rules meant the school could only allow a maximum of 4000 people on the school grounds. In 2015, the gala attracted 7000, he said.
Fuller paid tribute to the efforts of staff and parents who had worked much of the year on organising the return of the gala.
"Without the school community, it wouldn't happen. There's a group of dedicated parents who are part of the extended organising band. They've been working tirelessly on this."
Tickets are available from the school or at the gate on the night, but people are urged to get in early.
The gala's postponement date if it rains is November 18.
