Convicts who re-offended after arriving in the colony could be assigned to do hard labour in an iron gang, building and repairing roads and bridges at the frontiers such as on the western road over the Blue Mountains to Bathurst and the Great North Road to the Hunter Valley. Each man in the gang wore a set of leg irons, hot-riveted on by a blacksmith. When being mustered and marched to work, each man’s irons were attached to a gang chain like this one, to keep the men together, and to prevent any from escaping into the bush.
