It would be interesting to figure out what type of habitancies existed in the rest of Australia, on the unmarked areas. Is there anyway to logically figure out what habitancincy types likely existed in the other areas based on the distributions elsewhere? We could surmise that if Corybantic habitancies predominate in the centre of the continent, they might also in the far reaches of the continent, e.g. Victoria. Indeed there seem to be Corybantic communities on the SA coast, looking at the map. But we do find the Demonstrative group in NSW, likewise the far north on the eastern coast.
From historical descriptions of the Eora (Sydney) tribes, they didn't seem to have been Punctilious and I would guess more Corybantic. Aboriginals I meet in my.local area certainly include NA types, and other Aboriginals I've met with ancestry from NSW region do seem to be N or NP types. So in the past there might have been a sanguine polymorphic habitancy with a bent to NA and NPA types, or what have you.
