All the Aboriginal and Torres Strait Islander language groups of Australia, following the AIATSIS map.
I've tried to use the names/spellings in common use as far as practical! Comment below if there are alternative names or spellings you think should be included/accepted.
In the meantime, try spelling another way: 'D' is often interchangeable with 'T', 'G' with 'K', 'B' with 'P', 'TJ' with 'DJ' etc. Watch your 'NG' and 'NGG' combinations, your 'R' vs 'RR', and 'L/N/D' vs 'RL/N/D'!
Note: the SVG version of the map below is not an exact copy of the original and so some of the area shapes may be distorted - the aim is for the map to be used as a guide to show where nations are located relative to each other.
Could I suggest "Gudjal" and "Warrungu" as alternative acceptable answers for "Gugu-Badhun"?
Hope to see more great quizzes like this in the future. :^)
