however, it is clear from sources that particular writers were aware of it, in most instances referring to it by their local variety name or with a descriptor like 'this language with slight variation...'. It was not until the early 1900s, with the advent of Aboriginal Protection Boards, that non-Indigenous sources begin overtly naming wider language groups; this, however, was at a detriment to local dialect and clan names that were subsumed under the board's chosen name; Yugambeh-Bundjalung's position on the QLD-NSW border led to two standard terms Yugambeh/Yugumbir on the Queensland side and Bundjalung/Bandjalang on the New South Wales side. It was for this reason that Margaret Sharpe named the chain Yugambeh-Bundjalung, the terms being the most northerly and southerly respectively as well. Modern Yugambeh-Bundjalung-speaking peoples are often aware of and use the overarching terms Yugambeh and Bundjalung, some groups in conjunction with their own name e.g. Byron Bay Bundjalung – Arakwal. As these words also refer to individual dialects some groups object to their usage, Crowley and Sharpe both agree that Yugambeh referred to the Beaudesert dialect, also known by the clan name Mununjali, and Bundjalung originally referred to the Bungawalbin Creek/Coraki dialect, though the Tabulam people claim they are the original Bundjalung, and use Bandjalang in opposition. Geographic distribution Yugambeh-Bandjalang is spoken over a wide geographic area; the Pacific Ocean to the east and the Logan River catchment as the northern boundary, the Clarence River forming the south and south-western boundaries, and the Northern Tablelands marking the western boundary. Many of the dialects and branches are confined by natural features such as river basins, mountain ranges and dense bushland. Dialects Yugambeh-Bundjalung or just Bundjalung is used as a cover term for the dialect chain as well as to refer to certain individual dialects. At the time of the first European settlement in the mid-1800s, the Yugambeh-Bundjalung peoples on the north coast of New South Wales and southeast of Queensland spoke up to twenty related dialects. Today only about nine remain. All were mutually intelligible with neighbouring dialects. The dialects form recognisable clusters that share phonological and morphological features, as well as having higher degrees of mutual intelligibility.
