Mogumber Primary School opened on 20 June 1961, with the headmaster Mr James Quinn, formerly a teacher at Methodist Native Mission. The official opening took place on 15 September 1961 by Dr T.L. Robertson, the Director General of Education. This school was attended by children from nearby farms but the majority of children came from the Mogumber Mission. When the school closed in 1979, a Library was established in the building. It is now also the town's post office agency. The cache is located near a small memorial marking the old school site.
The Moore River Native Settlement Camp (later known as the Mogumber Native Mission) was established under the policies of the chief protector of Aborigines, AO Neville, and was originally intended to be a self-supporting farming community. Neville saw the settlements as a means of integrating children of mixed descent into the non-Indigenous society. But it soon morphed into a combination of prison camp, welfare hostel and dumping ground for the elderly and destitute.Throughout its existence, it contained a mix of people sent there under section 12 of the 1905 Aborigines Act — which allowed the government to forcibly remove people from their homes and gave rise to the Stolen Generations — and others who went there voluntarily looking for better living conditions. The children were trained to work as domestic servants or workers for farms and stations. But education was also a high priority at Moore River, as part of Neville's plan to make children of mixed descent fit into white society. Schooling was initially for three hours a day, and one archive photo shows children sitting outdoors behind a grass hut, using wooden boxes as desks. Later, a hall was used for schooling, and sports activities were set up for the children.
