The first exploration by Europeans was by Major
Thomas Mitchell who passed through the area in 1846. By the 1850s, settlers had moved in. The Jordan Creek/River (as it is variously known) was named after Harry Jordan, an early settler in the area. The town and locality name are derived from the railway station, which had been named Jericho in 1885 by railway surveyor and engineer Willoughby Hannam in a reference to the Biblical town of
Jericho being to the west of the
Jordan River, since it was the first station to the west of Jordan Creek. Jericho Post Office opened on 2 July 1885; a
receiving office had been open from 1884. Jericho State School opened on 20 February 1888. Jericho Methodist Church opened in October 1930. It became the Jericho Uniting Church following the merger of many Methodist, Presbyterian and Congregational churches into the
Uniting Church in Australia in 1977, but closed subsequently and is now in private ownership. It was at 15 Davy Street (). In December 2010, half of the town's houses were inundated by
floods. On 22 November 2019 the
Queensland Government decided to amalgamate the localities in the Barcaldine Region, resulting in five expanded localities based on the larger towns:
Alpha,
Aramac,
Barcaldine, Jericho and
Muttaburra. Jericho was expanded to incorporate
Dunrobin (all except the south-west corner),
Garfield (all except the western corner),
Grant (eastern corner),
Hobartville (south-western part),
Mexico, and
Narbethong (north-east corner). == Demographics ==
