Fr Jean Marie Janny, believing that the Trappists first responsibility in Australia was to the Aborigines, sets about establishing a new mission around the spring country of the Nimanboor on Disaster Bay using the grant of reserve land with 2,002 acres that Bishop Gibney had already secured. With the help of various tribal groups a new mission, set among scrubby dunes within sound of the sea, is built. The mission is named, the Assumption of our Lady, in honour of the day it opens.

Broome Diocese acknowledges and pays respect to the Traditional Owners and Elders, both past and present, of the lands on which Broome Diocese offices and operations are located.
