After a two-hour drive from the nearest main road, our 4WD can travel no further; me and my travelling companions will have to trek the rest of our journey to Aravira Primary School in Bougainville on foot. As we set off, a group of students from the school emerge from the bush in front of us. They smile, extend their hands in welcome and immediately offer to take my backpack.
I politely refuse, yet within minutes I regret my decision to turn down help. As we move through the long grass along the mountain ridge, the heat which a few minutes ago was manageable is now unbearable. I’m pouring in sweat. My backpack feels 10 kilograms heavier, and the ground beneath me feels as if I’m stepping onto ice. Ten minutes into our journey, I lose my feet, slip into a crevice, and land face-first in the nearest bush.
