Boulia is in the Central West Queensland and is located approximately by road south of Mount Isa. Boulia is at the crossroads of a number of outback routes, including the Boulia Mount Isa Road (which goes north-west towards Mount Isa), the Selwyn Road (which goes north-east to Selwyn), the Winton Road, which goes east toward Winton), and the Boulia Bedourie Road (which goes south-west to Bedourie). The Donohue Highway coming from the Northern Territory joins the Boulia Mount Isa Road just outside of Boulia, which together with the Winton Road forms part of the Outback Way billed as "Australia's Longest Shortcut", a gravel-and-bitumen road which runs between Laverton in Western Australia and Winton in Queensland.
