Gympie is a regional town in the Wide Bay-Burnett region of Queensland, Australia. It is about north of the state capital, Brisbane. The city lies on the Mary River, which floods the town periodically. Gympie is the administrative centre for the Gympie Region area. At the 2011 census, Gympie had a population of 18,602.
Gympie is famous for its gold field. It contains a number of historic buildings registered on the Queensland Heritage Register.
Graziers were the original European settlers. Subsequently, James Nash reported the discovery of 'payable' alluvial gold on 16 October 1867. At the time of Nash's discovery, Queensland was suffering from a severe economic depression. Nash probably saved Queensland from bankruptcy. A memorial fountain in Gympie's Park honours Nash's discovery. The Gympie Gold Rush Festival celebrates the event today. The Gold Rush Festival holds 10 days of cultural events in October. Gold mining still plays a role in the area's fortunes, along with agriculture (dairy predominantly), timber and tourism. The gold rush's rapid development led to streets that are in an irregular fashion.
Gympie Creek Post Office opened on 1 December 1867. It was renamed Gympie in 1868.
The railway from Maryborough completed in 1881. The North Coast railway linked Gympie to Brisbane in 1891. A fire brigade was in operation in 1900. The state declared Gympie a town in 1903. A powdered milk factory began operations in 1953.
Significant floods along the Mary River have caused inundations of the town in 1893, 1955, 1968, 1974, 1989, 1992, 1999, 2011 and 2013. The first recorded flood in Gympie was in 1870. Most of the floods occur between December and April and are typically caused by heavy rainfall in the headwaters to the south.
The highest flood ever recorded in Gympie occurred on 2 February 1893 when the river peaked at 25.45 m. Gympie was declared a natural disaster area during the 1999 floods. The river peaked at 21.9 m then.
Numerous highways and roads in and around the town which were destroyed or damaged during floods in 2011 will be repaired under Operation Queenslander. This is the name given to post flood reconstruction efforts in Queensland.
