A bush kinder or primary school is basically an educational place that is held in place that is completely or mostly natural setting.
Wikipedia describes it as:
“A forest kindergarten is a type of preschool education for children between the ages of three and six that is held almost exclusively outdoors. Whatever the weather, children are encouraged to play, explore and learn in a forest or natural environment. The adult supervision is meant to assist rather than lead. It is also known as Waldkindergarten (in German), outdoor nursery, nature kindergarten, or nature preschool.”
