I live up here, and have Indig' friends. I've worked in Crisis care and housing for the Sallies here too, and have recently returned from a volunteer trip to Wadeye(Pt Keats), the most notoriously violent community up here.
So, given the above, I feel I can speak with some little authority.
Yes, the Indig do have problems, and that DOES include racism, both against, and BY them.
They are starting off a dozen miles behind others right from the start, so it's that much harder for any individual to succeed. This is a fact, like it or not.
The bottom line though is that they are their own worst enemies, they hold themselves back, for a variety of typically human reasons, NOT related to any racial or social characteristics.
They are as much victims of our attempts to help them as they are of the original invasion, but that's life. The Nation as a whole has been trying to help for several decades now, with only a little to show for it. The Intervention has been the most successful try so far, and is extremely popular among the families and communities, it's only the drunks, the local big-wigs, and the Idealists who object to it. Forget what you hear on the media, the reality here in the NT is that it IS working, slowly, and it IS popular, by and large. And that's straight from the mouths of the people living under it.
Perhaps as we progress we will finally make a real difference, there's a growing groundswell of resistance to the current crop of "leaders", because they have wasted so much money and so many opportunities, and I feel it will soon come to a head, the Old Guard are as much the problem as anything else.
JMHO.
