Isaac Regional Council

Isaac Regional Council, south-west of Mackay, was formed in 2008 by the amalgamation of Belyando, Broadsound and Nebo Shires. It was named after the Isaac River which rises near Moranbah in the former Belyando Shire and runs generally south-east to join the Fitzroy River system. The river was named by the explorer, Ludwig Leichhardt, on 13 February 1845 after Frederick Isaac, proprietor of the Gowrie pastoral run on the Darling Downs.
