Moreton Bay’s Island Institutions: From Isolated Exile to Adaptive Archipelago

As the early colonial settlement of Brisbane (Meanjin) evolved from a penal outpost to a bustling port city, officials and policy makers developed explicit formal controls to protect mainland inhabitants from disease, social unrest, and “undesirable behaviour.” Three islands in Moreton Bay (Quandamooka) – Peel Island (Teerk Roo Ra), St Helena Island (Noogoon), and North Stradbroke Island (Minjerribah) – each became sites for a suite of institutions that were built and populated in response to a series of these early public health, immigration, and legal policies. Positioned strategically within Brisbane’s maritime network, these three islands housed a range of significant public health, penal, and social institutions for over a hundred years between the mid-nineteeth and mid-twentieth centuries. This paper contends that each such island institution exhibits a characteristic way that the colonial governance agenda from the mid-nineteenth to mid-twentieth century encountered “island-ness” through changes to its built environment. Although intended as individual and isolated places of exile, these island institutions in fact operated as an interconnected and interdependent network – more usefully considered an archipelago – where institutional control and island conditions combined in novel ways to produce a set of shared institutional conditions, characterised by interchangeability, porosity, and connectivity.
