Division of O'Connor

The Division of O'Connor is an Australian Electoral Division in the state of Western Australia. It is one of Western Australia's three rural seats.

The Division was named after C. Y. O'Connor, the Engineer-in-Chief of Western Australia who designed Fremantle Harbour and the Goldfields Pipeline. The Division was proclaimed at the redistribution of 28 February 1980, and was first contested at the 1980 federal election. The seat was a safe Liberal seat. It was held by Wilson Tuckey from 1980 before being defeated at the 2010 election by Nationals WA candidate Tony Crook with a large swing.

It has always been a rural seat, and was historically based in the Mid West, Wheatbelt and Great Southern regions of Western Australia with major population centres in Geraldton and Albany. A major redistribution in 2008, taking effect at the 2010 election, saw it lose its northern half to the new seat of Durack whilst absorbing large parts of the former Kalgoorlie. As of 2010, it is centred on the Great Southern and Goldfields-Esperance regions of the state (while incorporating the southern Wheatbelt), with major population centres in Albany, Kalgoorlie and Esperance. Local government areas within the electorate include Albany, Boyup Brook, Bridgetown-Greenbushes, Brookton, Broomehill, Bruce Rock, Coolgardie, Corrigin, Cranbrook, Cuballing, Denmark, Dumbleyung, Dundas, Esperance, Gnowangerup, Jerramungup, Kalgoorlie-Boulder, Katanning, Kent, Kojonup, Kondinin, Kulin, Lake Grace, Laverton, Leonora, Manjimup, Menzies, Narembeen, Narrogin, Ngaanyatjarraku, Pingelly, Plantagenet, Quairading, Ravensthorpe, Tambellup, Wagin, Wandering, West Arthur, Westonia, Wickepin, Williams, Woodanilling, and Yilgarn.
