Indigenous Australians and NT Land

I went to an Indigenous seminar the other day run by well-respected members of my university faculty and heard that the NT government (or is it the federal government) has Aborigines working for the dole in which they build their houses, then leases their land back to them for five years or something - something about a smokescreen for a landgrab and uranium?

I was hoping someone might be able to shed some light on the story. Thanks.
