The Wellington Valley Convict Station and Mission site, now known as Maynggu Ganai Historic Site (meaning "people's land" in local Wiradjuri language), contains the archaeological remains of the convict agricultural station that was established in 1823. The site, subsequently taken over by the Anglican Church Missionary Society as a mission to the Wiradjuri, operated from 1832 to 1844. Drawing upon archaeological survey, the extraordinary historical archive associated with this site, and an analysis of community consultative research, this article explores the role of this site in colonial cultural exchange, as well as the contemporary cultural meanings of this history and its physical remains for the community today.
