The Mid-Western Regional Council also incorporated the area of the historic Wyaldra Shire, which was abolished in an earlier round of local government amalgamations.

[citation needed] On 26 November 2004, it assumed the assets and operations of the former Mid-Western County Council.

The region also includes the towns of Gulgong, Rylstone and Kandos, the villages of Bylong and Ilford, and the localities of Aarons Pass and Bombira.

Most of the LGA is agricultural with a strong presence from coal mining, but it includes several historical towns.

Mid-Western Regional Council is composed of nine councillors elected proportionally as a single ward.
