It's not good enough to simply imprison family members who abuse others. You need to cut at the heart of the issue. And I dont think that rape/violence has previously been ignored out of respect of 'tribal law'. Of course they'd be arrested. The problem is their remoteness (the recent solution being more police).
They have a fundermental right to chose where to live, especially for cultural/traditional reasons. I dont want to get into this, but the unique link to the land, corresponding stories and communities are culturally enriching for us and the rest of the world. They aren't animals.
Costello was saying that their communities need an economic base relevant today - contrasting their communities with pioneer country towns, established for and thriving from wool/wheat whatever. But of course Aboriginals played a major role in, say, raising cattle on the old, huge gentry farms of yesteryear. If anything, the advances in agricultural technology rendered the significant Aboriginal role redundant. Is the state going to watch them starve? No. They just took their children to town, which failed monumentally.
Creating some incentive behind the welfare is the best bet and is currently going on (welfare pending school attendance etc). Aside from that, more investment in tourism. Some communities also do quite well out of leasing native title to mining companies etc, although this doesnt create work. I dont think that I can see the Native American solution of Casino building and self-exploitation taking off.
Oh, and fruit picking is masculating? I'd preference the petrol-can abandon to pass the time any, and every, day.
