Moogerah Outdoor Education Centre Brisbane Grammar School's off-campus centre at Pepperina Hill, near
Lake Moogerah, was opened in 1976 and is named the Moogerah Outdoor Education Centre (colloquially referred to as Moogerah). The school sends each form class from grades 8, 9 and 10 out to the campus to strengthen intra-class relationships and morale, as well as develop team-working and leadership skills. Year 11 outdoor education leaders also attend the camp to build the relationship between the senior, and younger students. The five-day programme includes such activities as rock-climbing, bushwalking, orienteering, canoeing, and a camp-out in the bush at the foot of a mountain.
