Student Life

International mindedness. Individualised experience.

TIGS community is built on Christian values, as we strive to treat each other with love and inclusivity. Through activities and events like TIGS Great Fete, School Productions, and Sports Carnivals your child will build strong relationships with peers and learn to collaborate with others. They will be part of one of the four School Houses: Kogara, Coligan, Aranda or Wolgal and engage in friendly intra-school competitions. Our Pastoral Care and Chapel programmes also encourage meaningful connections and provide opportunities for both personal and spiritual growth.
