On 15 March 2008, under the "Local Government (Reform Implementation) Act 2007" passed by the Parliament of Queensland on 10 August 2007, the Shire of Taroom was dissolved. Division 1 of the shire, centred on the town of Taroom, was merged into the Shire of Banana. The remainder of the Shire of Taroom, centred on the town of Wandoan was merged with the Town of Dalby and the shires of Chinchilla, Murilla, Tara and Wambo to create the new Dalby Region, renamed Western Downs Region on 29 June 2009. In doing so, Taroom became one of the only three former shires in Queensland not to stay intact, alongside the shires of Tiaro and Beaudesert.
