Shire of Yarriambiack: History
The Shire of Yarriambiack was formed in 1995 from the amalgamation of the Shire of Warracknabeal, Shire of Karkarooc, most of the Shire of Dunmunkle, and part of the Shire of Wimmera.
In January 1996 part of the Richardson River catchment east and south of Rupanyup was transferred from the Northern Grampians Shire to Yarriambiack after a further Local Government Board review.
