The Diocese of Willochra covers some 90% of the geographic area of South Australia.
It is a diocese of great contrast from the wineries and vineyards of the Clare Valley; the expansive horizon of the mid-north, Yorke and Eyre Peninsula wheat and barley paddocks; the semi-arid and arid lands as you move further north into the vast tracts of grazing land; mining and heavy industry; the fishing industry and tourism.
