Generally the more successful situations have been where the community has become more self-governing. It hasn't always worked, but there are some success stories.
The self-governing success stories seem to be when there was still a reasonable level of culture and social structure remaining untouched where the elders had the respect they deserved. There has even been I think a return to the local aboriginal community having their own more traditional courts with full jurisdiction. Of course it's always amusing to see the media grapple with some of the justice meted out by the traditional methods of spearing them. (hmm can't find a reference for this but I'm sure I read about it)
Obviously, the greater the influence of western culture though the more complex and difficult the problems. Where the traditional society and culture has completely being destroyed it's unfair to expect full 'integration' into either the traditional or western culture. I don't know what the answer is.
(also I'm not saying that *all* aboriginals fail to adapt or adjust and succeed in western culture but surely there is something that can be done for those that fall through the cracks)
Oh and for anyone who has no sympathy I suggest watching the movie 'Samson and Delilah' that was released last year.
