Greenbank was settled early, in the 1840s, when horse traders Jackson and Slack selected land here, later taken up by Adam Moody's Apple Tree Run. Farm selections opened through the 1870s on well-timbered land, with Teviot Road giving access to the Logan River for moving timber and farm produce to market. That changed dramatically from 1951, when the Commonwealth moved to acquire a large timbered farm in the north of the area for military use, despite opposition from local progress associations. The resumption was gazetted that year, the Greenbank Army Camp was established in 1952, and a further expansion in 1966, again opposed locally, added Timber Reserve 446 to the site.

Today the Greenbank Military Range covers roughly 4,500 hectares, heritage-listed and also managed as a flora and fauna reserve, used for training by the regular army, reserves and school cadets. Most of Greenbank's residential population lives south-west of that reserve, on land subdivided for rural-residential living from the 1960s onward. That's an enormous, continuous stretch of native bushland sitting directly against residential streets (far larger than the reserve or park most suburbs border) and it keeps a steady supply of termites, ants and native wildlife moving toward the nearest boundary properties.

For homeowners, that means Greenbank properties closest to the reserve boundary generally see more sustained bushland pest pressure than homes further south-west on the older 1870s farm-selection land, which carries its own risk from generations-old timber instead.
