The founding of the Catholic missions in Australia coincided with the defining drift of power and prestige within the nineteenthcentury Church. This was a period of chronic dissension among Australias Catholic communities, powerfully drawn by the ultramontane impulse and political manoeuvring to refer their problems to the Pope. Roman bureaucratic control, exercised through the Sacred Congregation de Propaganda Fide, was the single most important factor in the resolution of these problems and, consequently, in the determinative shaping of the colonial Australian Church. Based on extensive archival research, this study explores issues of process, politics and personality in the formulation of papal policy towards a part of the world that could not be more distant from Rome.
