The Brown-headed Honeyeater is found in coastal south-eastern Australia, from Queensland, mainly west of the Great Dividing Range, to New South Wales, Victoria and eastern South Australia, including the Flinders Ranges and the Murray-Darling Basin. It is also found in parts of south-western Australia, being widespread south of Point Culver through Menzies and Mt Singleton to Coburn and Peron Peninsula, but is rare in the far south-west or on the Swan Coastal Plain.
