Coonabarabran is a town in Warrumbungle Shire that sits on the divide between the Central West and North West Slopes regions of New South Wales, Australia. At the 2011 census, the town had a population of 3,175.
Lewis Gordon first proposed a town plan survey for Coonabarabran in 1859 although the area had been opened up by a Government-sponsored expedition in 1817. John Oxley found Aboriginal people living here the following year 1818 — later identified as the western language reach of the Kamilaroi clans (Gamilaraay is the spelling used by linguists). Kamilaroi people are still well represented in the region, having occupied Coonabarabran for approximately 7,500 years.
It seems no one really knows the source and meaning of the word Coonabarabran. It may derive from a person's name or from the Kamilaroi language word 'gunbaraaybaa' meaning 'excrement', translated earlier as meaning, 'peculiar odour', this possibly is a bowdlerisation. Another meaning is derived from an Aboriginal word for 'inquisitive person'. 'Coolabarabran' was the name of a station owned by James Weston in 1848.
Coonabarabran Post Office opened on 1 January 1850.
The township is located on the Newell Highway and the Oxley Highway, approximately halfway between Melbourne and Brisbane and can be reached in about six hours by car from Sydney. There are numerous motels, hotels, and caravan parks for travellers.
