Grace, 11, and Kayne, 10, will compete in the 100m and 4x100m relay in their respective age groups at the Adelaide-based competition in December.

Students from 15 countries are poised to compete in various sports at the School Sport Australia-hosted tournament.

St Pius Primary School student Grace, who recently won a 100m silver medal at the School Sport Victoria titles, said she loved the thrill of racing.

“The feeling of being fast and having everyone cheer for you, I just like it,” she said.

Grace started little athletics six years ago and knew “pretty much straight away” she had pace.

Our Lady Help of Christians Primary School student Kayne said he had no nerves approaching the Pacific School Games. He is working on his running technique with teacher and athletics coach Dean Kilpatrick and is looking forward to sharing his stories with with school friends once he returns.

“I’d like to thank people for supporting me and taking me there,” Kayne said.

Camperdown’s Ruby Darcy and Warrnambool’s Jesse Suter will also compete.
