 Many former child residents, including some of the Aboriginal stolen generation, have deeply emotional connections to Challoner Cottage because of their childhood experiences at Mittagong Farm Home.This significance may be enhanced if it is proved that the Challoner Cottage building itself was constructed in part from bricks, timber and other materials produced and processed at the Mittagong Farm Home by the children themselves as part of their training in trades.The place has potential to yield information that will contribute to an understanding of the cultural or natural history of New South Wales.
