First of all, the term ‘dragged’ is making some rather odd assumptions. There’s no reason to think any sort of force is being used.
Secondly, yes, I think it does make sense to treat those who are unvaccinated differently from those who are, given what Australian data tells us about the COVID outbreak here. I make no comment on what is happening in America or the data there. This is especially true when you are dealing with a medically vulnerable population - which indigenous Australians are, particularly those in certain regions including the one in question.
Thirdly, I think you need to understand the nature of these specific communities. They are tiny - I’ve visited Binjari, about ten years ago. It has about 200 people. Rockhole is even smaller. I doubt Rockhole even has a single shop - if Binjari does, it’ll basically be one shop, probably government subsidised. People don’t generally get much from those places - the people in these communities are used to food being brought in from Katherine. That’s how they live at the best of times. These communities only exist because some Aboriginal people refuse to leave their ancestral lands (and I think that’s their right) and so in some places are choosing to live in very, very marginal communities that only survive on government handouts.
There’s basically no infrastructure. It’s the norm, if a person needs any sort of significant medical intervention to move them somewhere else.
As for ADF involvement - the ADF get used in Australia in a similar way to the way the US uses the National Guard to deal with natural disasters and similar. It’s not sinister or unusual. It can happen anywhere in Australia, but considering there’s a decent sized RAAF base only a few kilometres away, of course, they are being used for relief purposes. People want to read all sorts of things into that that don’t apply.
