That is because there are two competing orthographies – the former (which is easier for English speakers to recognise) is said (Strehlow Research Centre) to be preferred by Western Arrarnta people themselves (so i am told) and the latter is preferred by linguists as it is more accurate (but less easy for English speakers to recognise).

Here’s two useful dictionaries for Western Arrarnta.
