Barcaldine is the regional council's headquarters, and is 520 km west of Rockhampton. The regional council's eastern boundary adjoins the Anakie gemfields and its western boundary is 70 km from Longreach. A north-westerly projection reaches nearly to Winton.

Barcaldine and Alpha, headquarters of the former Barcaldine and Jericho Shires, are on the Capricorn Highway and the Central Railway from Rockhampton. The railway was constructed in stages between 1883 and 1891 from Alpha to beyond Barcaldine, following pastoral expansion. A branch line from Jericho to Blackall was opened in 1908, and a locally-financed tramway ran from Barcaldine to Aramac (1913-75).

Centrally located Barcaldine has been and is the main town.
