Mount Ommaney, a residential suburb immediately west of the Centenary Highway, is 13 km south-west of central Brisbane. It was named after J.M. Ommaney, the nephew of Dr Stephen Simpson, an early landowner. Simpson's Wolston homestead (1853) is in Wacol, and his nephew was killed in a horse-riding accident in 1856.
Mount Ommaney is one of the Centenary suburbs, developed after the Centenary Bridge (1964) over the Brisbane River and the Centenary Highway. The suburb's first significant development was the McLeod Country Golf Course (1968) on Mt Ommaney Creek, a small stream below the rise where a service reservoir was installed. When the suburb's population approached 500 in 1979 a post office was opened. Apart from a Special School (1992), State primary and secondary schools are in adjoining suburbs. The district's drive-in Mount Ommaney Shopping Centre (1979) is in Mount Ommaney, just west of the highway, and has two discount department stores, over 90 other shops and a council library.
