Gayndah is the administrative and major population centre of the Gayndah Shire, which has a population of 2909 persons (ABS estimate 2003).

Exploration of the Gayndah area began in 1843. The first European settlers arrived in 1848, and the town was established in the following year. Agriculture and grazing have been the dominant industries of the area. The town is now the centre of Queenslands largest citrus growing area. The Gayndah Orange Festival is held every two years to celebrate this industry.

Gayndah was considered for the capital of Queensland, but lost to Brisbane because the river was not deep enough, thus making it impossible for large cargo ships to unload near the city. Gayndah is also the oldest official town in Queensland. The explorers Archer and Burnett establishing it in 1849.

Gayndah is Aboriginal for thunder.

The town clock was donated by Mr. Richard Apel Senior, a local pastoralist.
