"I'M really excited. I think high school will be better than primary school, except for the homework," Georgia McCarthy, 11, said.
Georgia was one of 20 students in the first year 7 class to start at Oran Park Anglican College last Tuesday.
Head of campus Naomi Wilkins said she was also new to the school, which opened in 2012.
"We're starting off with a lot more facilities than in other places I've worked," she said.
The school already has six classrooms, including a visual arts room, science lab, hospitality kitchen and music room.
New student Lachlan Roberts, 12, is looking forward to meeting new people and learning new subjects.
"Science and sport, things like that," Lachlan said.
"I'm also excited about music."
Senior school co-ordinator Steve Moynan said the year 7s first day went really well.
"The kids received their new iPads and iTunes vouchers," he said.
"We have two and a half acres of land here, lots of playground space.
"We're hoping to expand with year 8 next year. We've got room to eventually accommodate a thousand students."
