Boonah is a town in south eastern Queensland, Australia. At the 2011 census, the town had a population of 2,474. The area produces vegetables for the nearby Brisbane Markets notably carrots, potatoes, and cereal crops. Beef, pork and timber are also produced locally.
The town is positioned near the Fassifern Valley, McPherson Range and Main Range. It is surrounded by hills, including Mount French and other Moogerah Peaks. Frog Buttress is a popular rock climbing cliff on the north-west side of Mount French.
The town is serviced by the daily newspaper The Queensland Times and the weekly newspaper The Fassifern Guardian. The Bremer Institute of TAFE has a campus at Boonah, which has operated at limited functionality for several years due to cutbacks.
Boonah was established in 1882 as a service centre for the surrounding farms. Originally the area was known as Dugandan, after a farm that was occupied as early as 1844. Later as a settlement grew it became known as Blumbergville. A railway line was built to the area in 1887, with the name Boonah given to a rail siding. The main commercial centre moved from Dugandan at the railway terminus, to Boonah after floods forced a shift of the settlement to higher grounds.
