The sculpture will be sited on the flagpole lawn outside the school hall and features a disc of the night sky made wholly of a lattice of stars, which will allude to the rotation of seasons and galaxies. A central hub will pivot and be moveable either by hand or wind.
"This means the sculpture will be interactive and the students can rotate the major disc or inner form. They can quite literally reach for the stars."
The Centennial Shield will be the first work by Virginia King in the region and while remaining "under wraps for now", Mrs Field said, would be unveiled during the centennial celebrations in March next year.
The school will host an event at the school on October 18 entitled Introducing the Artist, at which King will speak to the general public and the school community for a $10 cover charge.
The event will run from 5.30pm and will be free to those who have made a donation to the sculpture project, which had been so far generously supported. Over half of the fundraising target had been reached, Mrs Field said.
