Teams of up to three students will be let loose on the island with a GPS system and series of questions that will lead them to 49 geo caches placed around the island.
Once they reach the spot, they simply mark the quiz sheet to earn points.
Rottnest Island Authority Community Engagement coordinator Rebecca Chaffer said the aim of the Geo-Challenge ” a partnership between the RIA and Nature Play WA, sponsored by HBF ” was to encourage children to enjoy the outdoors.
‘Kids are indoors a lot of the time and in classrooms but we are trying to get them to play in an outdoor environment,’ Ms Chaffer said.
‘Rottnest is perfect for that.’
Students will use physical education, maths, history and environment skills to complete the four-and-a-half hour initiative.
Several geo caches will remain on the island for holiday activities.
