Cabonne Council: History
The first Australian gold rush occurred at Ophir within the present shire boundary.
Cabonne Shire was formed in 1978 following the amalgamation of Molong Shire, Boree Shire and the greater part of Canobolas Shire.
A 2015 review of local government boundaries recommended that the Cabonne Shire merge with the Orange City and Blayney Shire Councils to form a new council with an area of 7,833 square kilometres (3,024 sq mi) and support a population of approximately 63,000. As a result of the state government's decision to not proceed with proposed council amalgamations, this no longer applies.
Previously part of Dubbo Regional Council, from 1 July 2026, the locality known as North Yeoval was included within the boundaries of Cabonne Council.
