Two points to note here.
First of all, in congregations you are "allowed" to go out of your territory and attend a different meeting, but that does not mean that you are free to attend the other because of the pressure applied. Similarly, the aboriginal congregation is "encouraged" to support itself and help each other. Whilst someone with your intestinal fortitude may indeed have no problem ignoring peer pressure, many people do not have the same ability.
Secondly, even if aboriginal people want to be segregated, that does not mean that it is not racism. Indeed it is then racism from the other side.
To discriminate means:
be, set up, or act on the basis of, a difference between, on the grounds of race, colour, sex etc.
(Little Oxford Dictionary]
Whether there are benefits to anyone by a policy of discrimination is irrelevant, as it is still discrimination.
If a white person only feels comfortable being with a white person and acts accordingly, it is racism. If a coloured person only feels comfortable being with a coloured person and acts accordingly then that too is racism. Being comfortable only with your own "kind" IS racism.
To claim to have a racially united organisation is to claim integration and a "blindness" to colour. That is, from within, the members would tend to not notice colour or race. Separating into race does not allow that to occur.
Also, you make out that Aboriginies have an "aboriginal" language. There is no common "aboriginal" language and the language you are talking about is simply a way of using english. That is like saying that because we have different phrases and word usage, Americans and Australians speak a "different" language. I can speak American, English and Australian and I can even understand Scotts, so in your definitions, that would make me multi-lingual.
Whether someone has a culture and/or is in a minority, is not relevant to unification.
Aborigines distrusting white Australians is no different to white Australians distrusting Aborigines.
