The Shire of Murchison incorporates 29 pastoral stations and a population of 114. Most properties are operated by family units with their main income from cattle, meat sheep and wool, with some goats. A small tourism industry is developing in the region with some stations involved in station stays and with the Murchison Oasis Caravan Park and motel units located at the settlement providing facilities for tourists.[5][6]
The Murchison Road District was gazetted on 3 August 1875. It absorbed the Upper Murchison Road District on 18 March 1912. On 1 July 1961 it became the Shire of Murchison following changes to the Local Government Act, which reformed all remaining road districts into shires.[8][9]
In 2004 the shire was expanded in area when the northern part of the Shire of Mullewa and an eastern section of the Shire of Northampton were incorporated into Murchison.[10]
Murchison Settlement
The Murchison Museum in 2020
In 1966, a new shire office, including a residence for the shire clerk was built, approximately 200 km north of Mullewa on the Carnarvon to Mullewa Road. In 1985, a roadhouse was built nearby and additional shire buildings, including a museum. The area surrounding the shire complex was gazetted as Murchison Settlement in 1988. It has come to include a few other houses and an Australia Post Community Postal Agent (CPA).
The Shire is the site of the Murchison Radio-astronomy Observatory, which lies 70 km east-northeast of Murchison Settlement. A sparse population – and its consequent radio "quietness" – is a factor behind the Shire being selected as one of the two sites for the Square Kilometre Array – a proposed array of radio telescope receivers with a total collecting area of one square kilometre. It is already home to two other major radio telescope facilities: the Murchison Widefield Array and the Australian Square Kilometre Array Pathfinder.
The Square Kilometre Array, or SKA, is a global radio telescope project involving institutions in more than 20 countries. The SKA will be the largest and most capable radio telescope ever constructed—50 times more sensitive than any other radio instrument. Australia and southern Africa will each host different components of the SKA. Management of the facilities at the SKA is coordinated by the CSIRO from the offices and laboratories at the Murchison Radio-astronomy Support Facility in Geraldton.[18]
As of 2023, 35 places are heritage-listed in the Shire of Murchison,[19] of which four are on the State Register of Heritage Places, among them the Boolardy Homestead.[20] The homestead, dating back to 1875, was added to the state register on 29 May 2001.[21]
