the aborigines are part of the same as the peoples that populated papau new guinea and many of the melenisian islands. they might have more curly/wavy hair. but their brothers across the pacific mostly have kinky/nappy hair like most Africans.
You said: " black means not only dark skin but also kinky/curly hair. thus the aborigines in austrailia and papau new guinea are black but the south asians are not."
Australian Aborigines do not have "kinky/curly" hair. Thus, by your own criterion, Australian Aborigines aren't Black, in the same way you've argued dark Sri Lankans aren't Black. Of course, that creates problems for your attempts at racial classification because of those who are genetically closest to the Australians.
