 Few documentary sources are available that describe the layout and operation of the lock hospital, which closed well before the lazaret, or record the lives of the people who lived there; making the remains of what was Queensland's only purpose-built island lock hospital an invaluable resource for further study.Similarly extensive are the archaeological remains of the lazaret; an important record of Queensland's largest and longest-serving island facility for the treatment of non-European Hansen's disease patients.The place is important in demonstrating the principal characteristics of a particular class of cultural places.
