History
In 1885, a number of Swedish immigrants from the ship Chyebassa established farms in the area. Early crops included oats, maize, potatoes and turnips. Horses and cattle were grazed and timber was cut. The Swedish settlement included O.Trulson, M.Trulson, M.Stjernqvist, M.Swensen, P.Swensen, N.Stjernqvist and P.Abrahamsen. Other early settlers were John and George Hubner who took up farms in 1893. Although the district acquired the unofficial name of Hubner from the Hubner family, when the local government Shire of Beaudesert tried to formalise it in 1987, it was instead decided to name the area Crestmead after a local housing estate. On 24 December 2012, 80 workers at the Dairy Farmers factory in the Crestmead Industrial Estate staged a protest at the factory to protest pay rates; the protest included blocking access to milk tankers. A very large number of police attended and protestors clashed with police.
