Donnelly River Mill, was constructed in 1949 and was a timber Milling Operation run by Bunnings Bros, located in the South West of Western Australia. The mill was serviced by a Private Branch Railway Line, running from Yornup to the mill (19kms to the west). The steam hauled trains, loaded with sawn timber, running to the WAGR Siding of Yornup, were the last Private Timber Rail Operations in Western Australia and ceased in March 1970. The railways along the branch line to Yornup, were pulled up in June 1970 and the Mill eventually closed in June 1978.
