The remains of the sheep wash are on the bank of an intermittently dry creek; the dam that retained the water there was washed away in a flood. The visible remains of the sheep washing process comprise a circle of timber stumps, which supported the turning loop of the twin rails from the wash to the shearing shed and which encircled the draining yard. Miscellaneous machinery survives including a centrifugal pump made by Robinson Bros & Co. (patent 1882) of Melbourne, jets under which the sheep were washed, and the end of the pump with a column to a head of pressure. The former Beaconsfield Station Sheep Wash was listed on the Queensland Heritage Register on 21 October 1992 having satisfied the following criteria. The place is important in demonstrating the evolution or pattern of Queensland's history. The former Beaconsfield Station Sheep Wash, thought to have been constructed in about 1893, is important in demonstrating the evolution of mass wool production techniques during the development of Queensland's pastoral industry. It is a good example of an attempt at mass, mechanised washing of sheep using available technology in a remote location. The place demonstrates rare, uncommon or endangered aspects of Queensland's cultural heritage. The former sheep wash is important as an uncommon example of a large-scale sheep washing system in outback Queensland. The place has potential to yield information that will contribute to an understanding of Queensland's history. The former sheep wash at Beaconsfield has the potential to yield information that will contribute to an improved understanding of wool production techniques in outback Queensland during the 19th century. The place is sufficiently intact to permit further study of the washing technique used at that location and to contribute to a broader understanding of the development of Queensland's wool industry. The place is important in demonstrating the principal characteristics of a particular class of cultural places. The former Beaconsfield Station Sheep Wash is important in demonstrating the principal characteristics of such a facility, the following key features being extant: a dam, washing trough, pump, water jet, and tramline for transporting the washed sheep to the nearby woolshed. The place has a special association with the life or work of a particular person, group or organisation of importance in Queensland's history. The former Beaconsfield Station Sheep Wash has a special association with the Fairbairn pastoral empire, one of the most extensive pastoral holdings in Australia at the time. It has a particular association with Stephen Fairbairn and Walter Anderson the owner and manager of Beaconsfield respectively, who were responsible for its development into one of Australia's foremost sheep stations.
