These dormitories were part of the Mona Mona mission in the 1950s, which members of the Stolen Generation have described as little more than a prison.
They argue it is racially discriminatory to compensate other groups, but not Stolen Generation members for alleged mistreatment.
From 1913 to the early 1960s, the former Seventh-Day Adventist Mission held mostly Djabugay children forcibly removed from their families.
Lawyers representing Stolen Generation members who were sent to missions in Mona Mona, Wujal Wujal and Hopevale in north Queensland will know in October if the Federal Court will allow them to proceed with the class action.
Glenis Grogan from the Mona Mona Action Group says it's unjust that non-Aboriginal people placed in state institutions were compensated under the Queensland Government's redress scheme, but not Aboriginal people in church-run institutions.
Cairns-based lawyer representing the group, Kirsten Lesina says about 90 members will be seeking compensation of up to $42,000 each; with possibly more members signing on if the class action goes ahead.
Ms Lesina says if the class action is rejected by the Federal Court, Stolen Generation members may take legal action individually.
The Queensland Government is not commenting as the case is before the courts.
